Armstrong Siddeley Motors Ltd. Memo from Mr Cutler to Mr Chapman: Girling disc brakes  PA1716/2/1/130  27 November 1952

1 Item

Contents:
Girling lent me a Mk.VII Jaguar fitted with these brakes. They have prepared a scheme for our 3.4 litre and in a telephone call today, they informed me that it will take approximately 6 to 8 weeks to make the prototype parts and I consider it would be very unwise to make plans for these as a normal production brake until we have adequately tested these units on both the sports car and standard Sapphire, as in spite of Girling's assurance, regarding their freedom from trouble, I consider the design both of the Girling and the Lockheed unit is likely to trouble due to the braking disc exposed for at least three-quarters of its diameter to water, mud and dust, which seems to me under conditions which are met say in Canada and America during the winter, would allow the discs to become coated with ice, either during periods of standing or whilst the brakes were out of use under ordinary driving conditions

The delivery position of the six-speed remote controlled synchro-mesh gearboxes released on 14 June 1951 is shown as follows: 2 Development progress: It will be noted that we have completed 1,975 hours of bench testing and 129,889 miles of road testing on various new type engines and new type motor cars. 3 Miscellaneous development: We had a discussion with Self Change Gears yesterday on the automatic gearbox. Investigation should proceed but it seems obvious that this box is too far away to contemplate bringing into production at any specified time. Production (A) During the year ending 31 July 1951, was 42.7 cars per week (49 week year), against a target of 50 cars per week, while our material allocation was 46 cars per week. (B) The average number of cars finished per week since the 1 August 1951, is 42. Attached note: Mr Chapman spoke to mr Johnson and Colonel Siddeley concerning the Bentley position. It has been agreed that Colonel Siddeley will wind this up as soon as possible

Engine progress is shown on page 1. Page 2: C The decision today on gearboxes is that only one is being considered for all the new cars, namely the YA Pre-selector fitted with electrical control. 2 Miscellaneous development proposals: (a) Consideration is now being given to an electrical/hydraulic control for the pre-selector gearbox which we hope will eliminate pedal control. Production: Our programme since the 1 August 1950 calls for 45 car per week. Finished cars 44.4 per week. It is clear that we have been living on our own fat and the high spots today are the supply of crankcases and certain stampings. It is thought that out of a total of 2,214 cars manufactured in the current financial year, at least 990 will have to be sent to the Home Market

Mr Chapman has received the approval of both Mr Sopwith and Sir Frank, to the scheme for marketing the new 3.4-litre motor car, as outlined by the directors of Messers Henleys. Current car production (a) By price reduction - of the alternatives given in his statement of the 13th August, Mr Henley favours the second, which gives a total estimated loss of some £32,000. (b) By cancelling current production. There are some 280 cars yet to build and on today's evidence, Mr Chapman is inclined to favour this solution. 3 New car costs. Mr Chapman is not satisfied that the estimated costs for the new car on the basis of 2,000 and 5,000 per annum have been dealt with on a sufficiently realistic basis, and it is most essential, before we proceed further, that a special investigation be made into BO items, manufacturing costs and adjustment to overheads

1 Present 2.3-litre car position. a) There are approximately 528 cars on the present sanction for disposal. 50 sets will be retained for spares and 25 earmarked for group requirements. b) The suggestions for dealing with the balance of 453 cars are shown below: i) On the 18 August, we agreed to the re-instatement of the 20% agents' discount. ii) It is proposed to reduce the total selling price from £1728 to £1596, the export figure remaining at £750 ex works. iii) The proposal in paragraph (ii) entails a loss of approximately £43,000. 2 With the object of setting a larger price differentiation between the present 2.3 and the new 3.4-litre motor car, an alternative price of £1557 would increase the loss to £43,000. 3 On today's information comparison of price competitive makes is as follows: Alvis 3-litre £1945 Daimler 3-litre £2334 Jaguar 3.5-litre £1774 Rover 2.3-litre £1487 Armstrong Siddeley Motors 2.3-litre £1596 or 1557 Armstrong Siddeley Motors 3.4-litre £1728 4 I feel certain that at a selling price of £1728 for the new car (this includes double Purchase tax and 20% agents' commission), we shall obtain a very substantial amount of business

(b) During the four weeks ending 25 January, we were cars behind our target of 42 per week. On the 28 March, 1952, we were 103 cars behind our target of 42 per week. The major reasons behind this fall in output has been due to the failure in the supply of Crankshafts from Messers Shardlows and also the failure to supply in full our weekly requirements of chassis frames from Messers Sankeys

Contents:
Present: Mr Chapman, Mr Johnson, Mr Saxton, Colonel Siddeley. Mr Johnson outlined the position with regards to British Panels, and considered that the price would be around £70,000. The position would be clearer after the creditors' meeting to be held 12 January 1950. Plan 1 (a) Accept Mr Saxton's proposals for gas turbine production at Ansty. (b) Colonel Siddeley to prepare layout of car manufacture in Burlington on basis of maximum 75 cars per week. (c) Layout (b) to be prepared as alternatives with and without car service department. Plan 2 Mr Saxton in conjunction with Mr Magson, to have a more accurate plan of the gas turbine scheme at Ansty prepared and will show what such a move gives in additional space at Parkside. Plan 3 Mr Johnson will continue negotiations with the object of buying the British Panels premises. Plan 4 The rough proposals which Mr Saxton put forward for moving the gas turbine development department to Ansty is quite acceptable. Plan 5

From Mr Cutler to Mr Chapman: In addition to the replating of the radiator grill, bumbers etc, which has been carried out during your absence, a thorough investigation to establish the cause of the fall of engine performance was immediately to hand. On stripping the engine it was found that several exhaust valve seats were in poor condition, this trouble had obviously been caused through slight sticking of the valves, which were fitted with the very first prototype single return spring, the outer spring being used only to return the rocker mechanism, The design was abandoned a considerable time before the engine was put into production and our main endurance running has been carried out on the present production type of valve mechanism, which is of the normal two spring type with the collar attached to the valve in the normal way. New valves, guides, collars and springs were fitted and the mechanism is now completely to production standard, including the camshaft. The engine compression ratio has been raised to 7:1 to bring the engine up to date and to take advantage of the premium fuels

1 Item

Contents:
From Mr Thornett to Mr Wright regarding the attached letter from Mr E H Siddeley asking for details of the introduction of the Wilson gearbox, I think the following information should help: Armstrong Siddeley detail drawings were being prepared in 1928 (first entry in drawing register is 17/4/28 and this refers to 30 hp). Self-change gearboxes were introduced into production as follows: 30 hp 1929; 20 hp Standard 1929; 20 hp Long 1929; 15 hp 1930; 12 hp (3-speed) 1931; 12 hp (4-speed) 1932. A number of earlier 30 hp and 20 hp models were converted to self-change and this conversion would be carried out in late 1928 or early 1929. I have attached a quick reference chart which no doubt Mr Ernest Siddeley will remember. This indicates clearly the introduction of the various models. No records are held in this office of the RNTF Torpedo engine. Following our conversation, I Understand you may be able to obtain this from records in the front offices

It has been decided to deal with this motor car under two headings, one covering design and development, and the other one, finance. The design and development minutes commence hereunder. Chassis. Frame The necessary drawings have been modified to cater for a wheelbase of 9' 3'. Engine: (i) Air intake noise. (ii) Excessive exhaust noise. (iii) Improved oil filler cap. (iv) Engine front mounting brackets. (v) Distributor. Gearbox: (i) Jumping out of third gear on deceleration. (ii) Judder associated with the mounting of the gearbox on the chassis. (D) Propeller shaft and axle. (E) Rear springs. (F) Rear shock absorbers; Experiments with the Teleflo type shock absorbers have been abandoned because of their continued failure on the pave. The units will be replaced by the Armstrong, which is the next cheapest to purchase. In the meantime the Girling will be used. (G) Front shock absorbers as (F). (H) Front suspension; this is approved. (I) Brakes; Mr Wright of Dunlop has informed me that any quantity production of disc brakes to be available by July 1955 is out of the question. Dunlop said that deliveries might begin in early 1956. (J) Overdrive; is approved with an operation planned for top gear only. (J) Automatic type gearbox; there are two types under consideration 9a) The Mnumatic; (b) The Magnetic. (L) Steering. (M) Radiator; is still not satisfactory. Further work proceeding. Body: (A) Petrol filler cap. (B) Seats. Mr Ashley is of the opinion that the present seating is completely unacceptable from a comfort point of view and the criticisms are too numerous to record and therefore Mr Henley has been requested to obtain the following seats: One bucket seat as fitted to the Hillman Minx; Bench seat as fitted to the Rover; One bucket seat as fitted to the Daimler. (C) Petrol tank; it is proposed to fit the dampers forward of the rear axle instead of aft, with the result of saving space. (D) Instruments: Mr Ashlwy records that basic instruments in the motor car are inaccurate and particularly commands the experimental department to see that these errors are omitted from Experimental cars forthwith.

It would seem unwise to release the front end of the car for tooling until the full effect of the alterations already agreed in regard to Headroom; Legroom; and Door hinging has been investigated and approved in conjunction with the main body drawing. 2 It is agreed that it will be necessary for the wings to be detachable to overcome accident and insurance problems and cost, and the only satisfactory method of carrying this out is by the bolting of the wings to the valance. 3 The cost of interior fittings: (a) On the 21 October, Mr Hurley indicated that general body details would cost approximately £190, together with tool charges of approximately £7,000. As indicated in the minutes of yesterday, it is considered that these costs are approximately £40 too high

(a) Revised rear springing: The revised rear springing has already been agreed. it is understood, however, that we are committed to the present rear spring up to a total of 6,500 cars.(b) Bump stop rubber: An improved bump stop rubber is available and will be fitted to PHP 135 tomorrow, Friday 26 November. (c) Anti-rolls bar: Tests have been carried out at Lindley which were the subject of a report dated 4 November 1954. Following these it has been decided to obtain more experience as to any possible effects and as a consequence the rear anti-roll bar has been removed from mr Ashley's Sapphire and also from the Mark II demonstration car PRV 116. The other demonstration cars will have the bars removed as soon as they are available. (d) Disc brakes: The first set of disc brakes were fitted to mr Ashley's car and were ready for road testing on the 22 October and mr Ashley's comments on these are that he experiences what appears to be fluid fade and the Dunlop people are visiting the works this afternoon to investigate. (e) Crankcase: As laid out in the minutes dated 19 october, an engine with a serious vibration complaint was installed in the Silverstone car ORW 429. The vibration continued after installation to a very marked degree. A redesigned Crankshaft was fitted and it is estimated, removed approximately 90 per cent of the vibration. Continuing on this investigation a stiffened crank case was substituted which showed a still further improvement. (f) Water pumps: A number of complaints are received about noisy water pumps.

Contents:
He covered 403 miles in eight hours, running at over 70 mph at times and the car felt comfortable at that speed. Sticking valves caused a serious problem which was done by a local garage. The problem was caused by the standard grade petrol bought locally in France. The valve guides don't like it anymore than the seats. We found that by adding an upper cylinder lubricant, it solved the problem of sticking valves. The car holds the road magnificently, and steers well and stops when asked

The power unit on these chassis is, of course, the Silent-Knight type of engine, and capable of developing 24 hp

Daily Express. Three, possibly five British firms have teams at work. So have four big corporations in the U.S. Runs on paraffin. The Rover Car Co of Solihull, are making great progress with a 100 horse power turbine engine suitable for fitting into the standard Rover chassis in place of their 18 horse power piston engine. It weighs only 4785lbs - 200 lb less than a piston engine. Armstrong Siddeley Motors, Coventry, have planted some features of their jet-age car, including a pneumatic transmission system which eliminates clutch and gearbox. The firm has been working on the gas turbine since 1942. Centrax Power Units Limited of Brentford, run by members of Sir Frank Whittle's Power jets team, are developing a 160 horse power turbine weighing only 250 lbs. It is equivalent to a 35-40 hp piston engine. Autin Motors have taken first steps to produce a gas turbine car. Their design would carry the power to all four wheels. Rolls-Royce of Derby, makers of famous jet engines, are also at work on a turbine car. When the turbine car arrives, motoring will be cheaper, safer and more comfortable, and less troublesome. Turbo cars, running on paraffin, will use hardly any lubricating oil. They will have fewer controls; less vibration, make less noise, and b easy to start

This is one of a selection of vehicles from the pages of 'Autombiles of the World' which was edited by WE de B Whittaker and Capt PA Barron and published in 1921. Illustrated: The Armstrong Siddeley 30 hp (4,960cc) was the first model offered. From 1924 front wheel brakes were fitted and the model remained in production until the early thirties although with a single cylinder block after 1926. The artist's impression of the Laudaulette version conveys the uncluttered but decidedly ponderous look that characterised early Armstrongs, but it is relevant to point out that the claimed chassis weight was the same as that of the E-type 30/98 Vauxhall; overall weight was in the region of two tons and a top speed estimated at 65 mph

It is regretted that flying hours between complete overhauls cannot be increased, as the hours flown by Beechcraft between overhauls is 740 hours. The Avro XIX and these Beechcraft fly on the same routes with a similar payload, they are faster than the Avro XIX (cruising 180 mph) although it is too soon to comment on the total life of either aircraft, the Misr company statistics Department show graphs to our detriment. To date we have had a fair service from the Cheetah XV engine fitted in the Avro XIX aircraft in service with the above company; with the following complaints: 1. After fitting replacement engines to one of the aircraft one was filling up the aux.box with oil as mod E.792 had not been incorporated (this engine was fitted with a BTH compressor). 2. Exhaust valves burning, guide wear is still our chief snag. Average exhaust valve wear is 4 per engine per 100 hours. Bad scoring of the housing by the oil retaining rings (prop control). These rings are rotating to cause deep scoring to clearance error. Cylinder wear is not excessive. Dunlop brake box has caused considerable delay on three occasions. The rubber sock between two metal ends of the relay valve splits

Contents:
'I should like you to know that by the early part of 1953 we shall be more than occupied in meeting the delivery schedule for Double Mamba and Sapphire engines, and on this account and in view of the MoS decision not to buy any further Cheetah engines but to fit Alvis products, coupled with the fact that we have no firm orders for new engines after June 1951, and that all Cheetah work had to be wound up within our organisation by the end of December 1952. Wood has been advised of this decision, so there should be no ambiguity about further supplies.'

Cheetah, extract from minutes dated 6 June, following meeting with Mr Golovine  PA1716/3/1/38/13  25 June 1951

1 Item

Contents:
'Part 2: It is clear that we cannot at this stage hold fast to my decision not to receive further orders for Cheetah engines after the end of this month and to close down all Cheetah new engine manufacture by the end of December 1952. Recently, we have decided to establish the Cheetah repair section at the main Quinton Road building, and we shall therefore continue to undertake this work indefinitely. We are likely to receive an order for 35 engines from Spain, which of course, will come out of the existing actions covering 80 engines, but on the information supplied by Mr Rudgard on the 29 May, it will be seen that even for these 35 engines, there is considerable important outstanding material. Provided an order for these 35 engines is placed in June or July, we can say delivery will commence 8 months from receipt of order at the rate of 12 per month.'

Bitteswell Flight Testing (A History)  PA1716/4  1946 - 1956

Contents:
In mid-1946 Mr BH Slatter was appointed Flight Engineer, directly responsible to Mr WF Saxton, Chief Engineer. In this capacity he was given the task of forming the Experimental Flight Section at Bitteswell for the flight development of engines installed in flying test beds. The department consisted of five technicians, who were responsible for analysing the performance records obtained as well as carrying out the actual flying duties. At a later stage, due to the very greatly increased amount of development flying, more technicians were employed and were divided into two groups. One based at Bitteswell, mainly for flying duties and the other at Parkside, later Ansty, to carry out more detailed performance analysis and the issuing of preformance brochures. Squadron Leader Waldo B Price-Owen was appointed Chief Test Pilot in 1947 when the first aircraft was ready for delivery to Bitteswell. This was Lancaster ND.784, which had a Mamba engine installed in the nose by AST Hamble, and was delivered in October 1947. Prior to this, a limited amount of development flying had been carried out on the ASK engine installed in the belly of the same Lancaster operating from Bruntingthorpe. By 1951, six different types of engines were being developed at Bitteswell, using 10 different aircraft, this being the highest number of types used in one year. Engine flying hours increased steadily until 1956 when a total of 2,433 hours was achieved. From then until March 1959, a decrease in flying hours became noticeable, due mainly to the cuts in the Defence Programme, but a reasonably high standard was maintained, principally on the Sapphire and Viper engines. Mr W Wright formed the Instrument Section, which now incorporates an electronic laboratory, which among other things, has been responsible for producing a sensitive means of recording engine conditions in flight. The photographing of intake de-icing, and vibration instruments, with the Siesmic generator and barium titanate accelarometer type pick-up in flight. Three technicians were permanently employed on liaison duties, and a flight section technician was always present during initial engine installation, and initial flights of prototype aircraft at outside manufactures establishments. Liason with the RAF and RN and in particular A & AEE Boscombe Down, when aircraft were undergoing special trials was also the responsibilty of this department. Technicians also accompanied aircraft abroad during tropical trials and at sea during carrier trials. The department was sub-divided into two sections; Pure Jet under Mr Bowers and Propeller Turines under Mr Bortkiewicz, until Mr Bowers resigned to take up the position of Technical Sales Manager and Mr Bortkiewicz became Development Engineer (Flight), covering both sections. The merger of Armstrong Siddeley Motors and Bristol Engines on 1 April 1959 resulted in the Department moving to Bristol. 1947 The first of the flying test beds arrived at Bitteswell in October.

In recording this discussion, the Gloster pilots' remarks are quoted in full and our answers to each appear immediately beneath. It should be recorded that S/Ldr Waterton stressed the fact that the contents of his appreciation were not necessarily a criticism, although that word does appear in certain sections of the report. he also stated that whilst he has concluded by saying that the Sapphire is not considered fit for service use, the same would also apply to the Avon RA.2

On the 2 January 1953 a note was issued referring to the necessity for revising the performance curves for AS Ma.6, AS Ma.3, and AS Ma.D3 (Gannet) engines. A copy of the curves for the AS Ma.3 (Gannet) engine is attached. This replaces the original set dated December 1951. In general, the power at altitude is increased relative to sea level and the specific fuel consumption throughout is higher in order to be consistent with AS Ma.D.1 (gannet) figures

Memo from Mr Slatter to Mr Lindsey: Notes on a visit to Hawker's at Dunsfold re. Sapphire Hunter criticism  PA1716/4/2/47  13 March 1953

Former reference: Biteswell Flight Section

1 Item

Contents:
Discussion of criticism of the Sapphires: Mr Duke, Hawkers, said that on some occasions during starting, the engine speed dropped slightly after reaching 1800 or 2000 rpm before again accelerating. This suggests that the starter panel cut-out is set too high and that the starting spill valve electrical system in the aircraft may not always operte correctly and we asked Hawkers to check these points. Governor stability and creep and jet pip temperature limitations: Mr Duke emphasised the difficulty of operating the engine at high performance at altitude. he also pointed out that, because we had set down for take-off rpm on the ground to alleviate the creep trouble now occuring at high pipe temperature was still present despite the fact the engine had been derated by removing two segments from the nozzle

Lancaster SW.342 (ASZ.107 & AS Sa.1) Bitteswell. The aircraft has been grounded all month whilst work was carried out to both Mamba and Adder installations and also the aircraft has been undergoing a 50-hour inspection. Dakota KJ.839 (ASZ.166/167) Bitteswell Flight test have been carried out during the month in connection with tests on the new Ultra stall warning indicator. Marathon VX.331 (ASZ.117/118& 127) Hatfield Whilst the aircraft was being prepared for demonstration at the SBAC show, the port engine (ASZ.118) seized and had to be replaced by ASZ.127. It was later found that the auxiliary drive lay shaft had seized. In addition there were two compressor blade failures. Apollo G-AIYN (ASZ.123/128/131/133) Baginton The trouble with the jet pipe temperature controls reported last month has not been entirely eliminated and it appears that most of the trouble has been due to faulty aircraft wiring. Gannet VR.546 (DM.210) White Waltham The starboard PCU was removed for fitting to WE.488 and the units are now to be modified to take pre-production type PCUs which are now available. Gannet WE.488 (DM.205) White Waltham. After re-installing engine DM.205 which had a propeller shaft oil leak the aircraft was prepared for display at the SBAC show. After its return from Farnborough, the aircraft is now being prepared for demonstration flying in France. The oil leak from the propeller shaft is not sufficiently severe to warrant replacing the engine by DM.204 which does not incorporate the modified drain cover. Blackburn WB.797 (DM.209) Bitteswell. All flying during the month had been carried out using diesel fuel. No change had been observed in normal handling of the engine, but considerable trouble had been experienced due to igniters being coated with carbon after only a short time in the engine. Lancaster TW.911 (ASP.109/110) Bitteswell; Wyvern VP.109 (ASP.112) Farnborough. This month had been entirely devoted to carrying out resonance testing in connection with vibration investigation. Wyvern VW.876 (ASP.876) (ASP.111) Farnborough. The aircraft was grounded throught the month following the failure of the pilot's canaopy during catapult launching. Wyvern VW.867 (ASP.126) Boscombe Down & Merryfield. Some flying has been carried out by various pilots including S/Ldr Starky to assess the handling of the engine with he ECU made inoperative. These tests have confirmed the opinion held that tahigh air speeds this would be satisfactory but that an ECU is essential for handling at low speeds and on deck landing cut. Wyvern VW.868 (ASP.115) Bitteswell. Several test have been made during the month to obtain further records of engine handling with accelerated sensitive PCU. The tests have been made with the rpm set up correctly to 7,800 and 8,000 rpm. Selected rpm still appear to wander about the datum setting but the vibration is at present not considered of great importance. Lancastrian VM.733 (AS.Sa.99/100) Bitteswell. The functioning of the high energy ignition system fitted to the first engine was tested at all altitudes up to 35,000 feet. After some early troubles with shorting of the plugs across the ferrules. UP to 35,000 feet starting was successful. Meteor WA.820 (AS.Sa.105/108) Bitteswell. After return from Moreton Vallance following the record climb, the aircraft was prepared and sent to the SBAC display for exhibition in the static show. Hastings TE.583 (AS.Sa.102/104) Bitteswell NGTE. Instrumentation work was carried out throughout the month in preparation for windmilling tests. Canberra WD.933 (AS.Sa.114/115) Bitteswell. Following several practice flights, the aircraft was flown to Farnborough for the SBAC display and it was demonstrated daily. Gloster GA.5 (AS.Sa.111/112) Moreton Vallance. Ground running commenced on this aircraft at the end of the month. A run at full throttle on the starboard engine resulted in a collapse of the air intake damaging the compressor blading. Both air intakes are to be modified and a spare engine (AS.Sa.117) will be installed

Hunter WB.202 awaiting completion of airframe inspection before installation of Sa.128.This engine which was in difficulty with handling trouble at the end of last month was finally cleared on the test bed and despached to Hawker. Sa.118 was run on the test bed on return from Hawker, but the blow out and handling trouble experienced in the aircraft could not be repeated. Alternator drive shaft seal failures have continued to occur on the Victor WB.771. Modified seals with reduced interferenece were fitted but one failed again after five-and-a-half hours running. Double Mamba aircraft (Gannet): WN.340 after return from carrier trials last month crried out some intensive flying at Ford RNASD before returning to the carrier to take part in intensive deck landing trials. WN.339 which has now been repaired following a taxiing accident was held in reserve for the carrier rials but was not reqired. VR.546 is at Farnborough for auto pilot tests but some vibration trouble has bewen experienced and is being investigated. Pythom aircraft (Wyvern): Following the dcision to ground all single disc turbine engines, all aircraft have now been fitted with twin discs. Further carrier trials were carried out during the month by VZ.777 and VZ.774. A further case of low power at take-off which could not be adjusted without affecting the idling setting was reported on the engine of VZ.777 (ASP.278). Mamba aircraft: Following the inspection of Seamew XA.209, the engine rpm at idling were erratic and it was found that the flow control filter had become blocked

This flight was specifically carried out to obtain a vibrograph recording of the elevator tab flutter generally experienced at high forward speed in this aircraft. A dive was commenced at 17,000 ft and the tab began to flutter. At 390 knots increasing in severity with increased forward speed. At 435 knots, the aircraft maximum speed, the dive was discontinued. During the pull-out, on application of 'g' the vibration reached its peak and finally faded out at 370 knots

I met Sqadron leader Wharton, the test pilot and other flight section personnel. In the main, the comments they made about the Sapphire were in keeping with those made by Hawkers with their Hunter WB.202. RPM overswing on the take-off and there is governor creep with full-throttle climb. At high forward speeds at any altitude, the engine is extremely sensitive to the slightest throttle movement

Comparison test of engine handling and behaviour on the Sapphire and Avon Hunters. Page 6: Conclusions 6.1 Several improvements must be affected on the Sapphire in order in order that it may compare favourably with the Avon in this installation, irrespective of the few advantages of the Sapphire at present. 6.2 It may be mentioned here that a negative creep control type pump is being developed for the Sapphire engine which will prevent the rpm and JPT reaching limits during a full throttle climb. Also amodified fuel flow control is being developed which should also cause the engine to give much reduced idling rpm and thrust at high altitude. Furthermore, a modification is to be incorporated which will make the throttle movement/thrust curve linear and so greatly improve engine handling throughout the throttle range. When these refinements have been perfected and incorporated, it is thought that the Sapphire will be getting somewhere. 7 Recommendations: 7.1 It is strongly recommended and considered essential that one of the early production Sapphire Hunters be allocated to Armstrong Siddeley Motors at Bitteswell for development work on the engine. Such items as high idling thrust at altitude and difficult selection of rpm at the higher engine speeds are aggravated on the Hunter already mentioned. 7.2 Squadron Leader Duke has complained that the IAS of the Sapphire Hunter at 1,500 ft and full power does not equal that of the Avon Hunter, although this must be due to increased drag on the sapphire model. He also complained of very excessive oil temperatures at high indicated air speeds and low altitude after 2 to 4 minutes flying at full power. This is attributed to a rise in structural temperature due to friction of airflow over the structure. It is impossible to carry out such tests as these with the present Sapphire test bed (Canberra), consequently faults are being discovered outside Armstrong Siddeley Motors that could have been recitfied earlier had a high-speed aircraft been available. 7.3 It cannot be too strongly stressed how urgently a Hunter or equally fast machine is required by Armstrong Siddeley Motors.

The following is a report of an endurance flight using one engine for cruising and using two engines only for take-off, changing over engines in use for landing. Page 5 Remarks: 20. The vibrations expected under conditions of cruising on the starboard engine with the port propeller feathered were unpleasant and uncomfortable. It should be noted, however, that the weather conditions at the time were such, as to give rise to much turbulance. It will be noted that there was a failure of the circuit breaker fitted without the device moving to the 'open' position. During the flight the starboard engine was throttled back from 51,000 ft onwards and the port from 54,000 ft being momentarily opened up to full throttle for readings at each level. It can be seen that the JPT on opening up to full throttle immediately rose above its limitations and it is stressed that these readings were taken immediately and did not have any time to settle

The following notes give a brief explanation of the principle troubles with current Sapphire engine controls together with some indications of what is being, or could be done, to alleviate them. The chief criticism from pilots of the functioning of the system are: (a) 'negative creep', by which is implied the inability to operate at or near the limiting jet pipe temperature in full throttle climb, and (b) random variations in engine rpm which occur at full throttle or fixed part throttle, especially since we do not achieve consistency in this respect from one engine to another

Contents:
Our view was to obtain from BOAC the size of aircraft required by them for future operation in terms of all-up weight and passenger accommodation. They are opposed to weights of about 200,000 lb and over owing to restricted airport use. There is no ideal number of passenger, but 100 at tourist rate would be acceptable. The conclusions reached by Avro in their comparison of the relative merits of the P.146 and Olympus versions of their Atlantic aircraft were explained. The latter version consists of a new fuselage but maintaining the Vulcan wing, the all-up weight for 100 passengers being 204,500 lb. The P.145 version is virtually a new aircraft throughout owing to the size of the engine

Contents:
Mr Golovine: I understand that the Hunter Mk.2 has flown twice on Thursday, April 2. Quoting from Mr Palmer's note on 8 April: ' ...These were the first flights following installation of the replacement engine Sa.128. During these flights, excessive jet pipe temperature was experienced in climb and in order to keep the aircraft servicable over the holiday period the four large nozzle trimmers were removed and four small ones fitted...'. Mr Slatter: After Sa123 was installed, excessive jet pipe temperatures were noted, even at low altitude. The four large trimmers were replaced by four small ones, which brought jet pipe temperatures in line with the expected values

Contents:
Page 1 of the performance data for the general version of the Mamba Ma.6 and Double Mamba Ma.D.3 and AS.Ma.D.4 issued during April 1953, reference is made to reducing the jet pipe diameter in order to maintain optimum performance at higher forward speeds. This, of course, is incorrect since the required reduction in exit area would be affected by fitting the appropriate nozzle to the standard size jet pipe. Attached are copies of the appropriately amended pages to replace the originals which should removed and destroyed

1. Page 3 Engines for prototype aircraft: Sapphire 9, two conversion sets £33,500 converting two sa.7 engines allocated form DEP production. These are required for the Ashton flying test bed allocation to Armstrong Siddeley Motors for flight development test of the higher powered Sapphire engines. The total sum for this section of these estimates then becomes £651,500 instead of $ 618,000 2 Page 2 design and supply for development: The two items for the 15,000 lb ATO rocket covering 5 engines at £31,000 is to be treated as an alternative project to the other rocket work specified and under these circumstances the sum of £31,000 will not be included in the total estimates

D.Eng.RD: 1955-56 development and research estimates  PA1716/4/6/28  11 November 1955

Former reference: D.Eng.Rd/estimates

Contents:
The overall spend of £2,713,213 at 96% shows that we underspent £110,000, this is considered reasonable at this juncture. Engine supply: The Mamba at 786% is £4,500 overspent, which is high, but as this only covers supply of three engines for the Dakota and these are now completed, this is within the total estimate and should be satisfactory. The Viper at 39%. £31,000 underspent is very low, this probably being due to the cancellation of the Avro engines. Flight testing: The Python at 29%. £1,500 overspent. The Mamba at 24% underspent is understandable as the aircraft has been awaiting the engines. These have now been supplied and considerable flying has been done which should soon balance his section

1955-56 D.Eng.RD development and research estimates  PA1716/4/6/29  26 October 1955

Contents:
The estimates proposed by Mr Weir are £52,000 in excess of the Armstrong Siddeley Motors budget estimates of August 12 (fourth issue). Since the Armstrong Siddeley Motors budget was submitted to the D.Eng.RD, two further contracts have been agreed with D.Eng.Rd for inclusion in the fiscal year, and these are included in Mr Weir's estimates. 1 30,000 lb rocket combustion chamber research contract 8720/SO20066 received. £20,000. 2 Conversion of gannet aircraft for DM.8 engine. Contract cover has been applied for to MoS. Mr Pearse's letter of 13 September 1955, to Mr Baker. £50,000. This, then, shows a deficite of £18,000 against the Armstrong Siddeley Motors budget. The following internal adjustments to Mr Weir's estimates are considered necessary if we are to do the work we propose in the Armstrong Siddeley Motors budget. Attached is the tabulated budget breakdown
