A, 138 FLIGHT, 3 February FROM ALL QUARTERS Sir Harry for Avro A CIVILIAN post, as managing director of A. V. Roe & Co Ltd,has been announced for Air Chief Marshal Sir Harry Broadhurst, GCB, KBE, DSO, DFC, AFC: he will take up the appointment followinghis retirement from the RAF on March 1, wnen he relinquishes the post of Commander Allied Air Forces Central Europe, inwhich he is succeeded by Air Chief Marshal The Earl of Bandon, GBE, CB, cvo, DSO (see Service Aviation, page 161). As managing director of Avro, Sir Harry will be responsiblefor, among other things, Vulcan, Blue Steel and Avro 748 pro- duction. He succeeds Mr J. A. R. Kay, who was recentlyappointed sales director of Hawker Siddeley Aviation Ltd, the parent aircraft company. It is proposed that Sir Harry should alsojoin the board of Hawker Siddeley Aviation Ltd. Commenting on the Avro appointment, Sir Roy Dobson, vice-chairman andmanaging director of the Hawker Siddeley Group, described Air Chief Marshal Broadhurst as "one of the great commanders of ourgeneration," adding, "he will be a great asset to our organization." Dowty's Boulton Paul Bid DETAILS of a bid—described as "£2 million plus"—by theDowty group for Boulton Paul Aircraft Ltd were disclosed last week. Dowty are offering 8s in cash and one of their 10s sharesfor every two Boulton Paul 5s ordinary shares, of which there are 2m. The bid, worth £2,137,750, values each Boulton Paul shareat 21s 4?d; on the London Stock Exchange on January 26, when the news of the offer became known, they went up by a shillingto 18s then rose to 20s. Directors of Boalton Paul have disclosed that profits before taxfor the last financial year (to July 31, 1960) are expected to be around £350,000. They are recommending shareholders to acceptthe Dowty offer. Fiat 7002 Flies FOLLOWING more th3n a year of ground-running, the Fiat 7002helicopter made a successful free flight of 30min duration at the company's Turin/Caselle airfield on January 26. The 7002 is autility helicopter with two-bhde rotor driven by cold tip-jets supplied by the Fiat 4700 compressor turbine. Both engine andairframe were designed and made by Fiat under contract to the Italian Defence Ministry and the Mutual Weapons DevelopmentProgramme. RB-47 and U-2 SIMULTANEOUSLY with President Kennedy's first Press con-ference, held on Wednesday of last week, the Russians released the two survivors of the USAF RB-47 which was shot down over theBarents Sea on July 1 last year while on a reconnaissance flight from Brize Norton. The President announced the release of thetwo officers concerned, Capts F. B. Olmstead and J. R. McKone; and later he referred to the flight over Russia on May 1 last yearof the Lockheed U-2—whose pilot, Gary Powers, is serving a ten- year sentence in the Soviet Union—and said that he had directedthat flights penetrating Soviet airspace should not be resumed. Nuclear Propulsion IN a main lecture to the Royal Aeronautical Society, beingdelivered before the Swindon Branch yesterday, February 2, Mr A. D. Baxter, MEng. MiMechE, FRAes, executive director(engineering) of the de Havilland Engine Co, presented a most valuable assessment of nuclear power, with particular referenceto aircraft and spacecraft propulsion. Starting with the first prin- ciples of gas turbines and nuclear reactors, Mr Baxter's paperleads into a discussion of the fundamentals affecting the design of aircraft nuclear turbojets, calculations being based chiefly uponM0.9 at 36,000ft or M2.2 at 50,000ft. The accompanying drawing shows a suggested closed-cycle installation in an aircraft designedfor the latter case The paper includes curves plotting thrust against Mach number for a closed-cycle engine at heights betweensea level and 60,000ft, and also suggests an analysis of total pro- pulsion-system weight. Mr Baxter's conclusion is worth reproducing in full: "In thepast few years, reactor developments have confirmed earlier views that nuclear-powered flight is technically feasible, and they havegone some way towards overcoming some of the earlier difficulties. The open-cycle turbojet and the closed-cycle gas-cooled reactorsystem both have possibilities of providing adequate power for RAF TO AVRO: Air Chief Marshal Sir Harry Broadhurst fle/t), appointed managing director, A. V. Roe & Co Ltd. He is being suc- ceeded as Commander, AAFCE, by Air Chief Marshal the Earl of Bandon (right). See first news-story sustained high-altitude supersonic flight, although only with largeaircraft. When shielding is not a vital factor, as in unmanned rockets, the weights become much less. In both cases, the questionof development in this country depends upon an assessment of our future role in world politics and technology. The precisebenefits cannot be stated, but there should be sufficient advantages to justify a modest programme of research and development atthis time. In conjunction with programmes on supersonic aircraft and high-temperature reactors it could provide a relatively inex-pensive, but none the less valuable, vantage-point from which progress in any appropriate direction could be started." Royal Aero Club Awards ANNUAL awards of the Royal announced last week. Aero Club The list is as follows: — for 1960 were Britannia Trophy: Mr T. W. Brooke-Smith, "for his work on theShort SC.l, culminating in his performance at the SBAC Display, when, for the first time, true vertical take-off was demonstrated, followed bytransition to normal flight and, later, a vertical landing." Geoffrey de Hayilland Trophy: Mr V. H. Bellamy, "for flying aSpitfire 8 in the air races at Cardiff on June 4, 1960, at 254 m.p.h." Bronze Medals: Mr B. F. Collins, for his work in building upSouthend Airport and for his active interest in aviation over a number of years"; Mr J. M. Houlder, "for his services over the years to lightaviation in the field of aerodrome operation, light-aircraft radio develop- ment and his demonstration of the all-weather possibilities of this typeof aviation"; and Sgt J. Williamson, RAF, "for his achievements in British gliding and the continuous and unselfish work he has performedon the gliding instructional side." Louis Breguet Memorial Trophy: M Charles Marchetti, "for his workon the design and development of French helicopters, with particular reference to the Alouette." William Geoffrey Cullen WE record with regret the death on January 13 of MrWilliam Geoffrey Cullen, chief accessories engineer of the de Havilland Engine Co since 1948. An early colleague of MajF. B. Halford, whom he joined on the design side in 1928, Mr Cullen became chief installation engineer of D.H. Engines in1944. Born in 1896 and educated at Clifton and Cambridge, he joined the RFC in 1915; invalided out after an accident in 1915,he rejoined in 1917. M2.2 AT 50,000ft is the design point for this hypothetical aircraft, powered by six turbojets fed by a closed-circuit nuclear reactor. Shield- ing is shown shaded. The design was described by Mr A. D. Baxter. of D.H. Engines, in a paper referred to on this page MM fill Mini
