FLIGHT, 13 May 1955 607 First Dutch Hunter HUNTER production is now going forward in three countries:Great Britain, Holland and Belgium. While large-scale deliveries of Hawker-built machines are being made to the R.A.F.,the first aircraft of a sizeable combined NATO and Dutch Govern- ment order has now made its first flight from Schiphol. Altogether,NATO orders call for 112 Hunters to be built by Fokker in Holland and S.A.B.C.A. and Avions Fairey in Belgium, and the DutchGovernment has ordered a further 156 Hunters from Fokker. The initial machines are being assembled from parts flown overto the Fokker factory from Britain; later aircraft will be entirely Dutch and Belgian-built. Fokker's chief test pilot, Gerben Sonderman, made the firstflight, and "Jas" Moll, another Fokker test pilot, has now also flown the aircraft. Reports from Holland indicate that Hunters—they will be Mk 4s and 6s—are eagerly awaited by the Dutch Air Force. Some new details are given by Avia-Vliegwereld.The push-button undercarriage control, for instance, is so posi- tioned that the wheels can be raised after take-off by "pointing" theleft forefinger with the hand still on the throttle. The flap control is a short lever (a completely different shape from that of theundercarriage control) which permits fine adjustment of flap setting. A number of hydraulic and fuel pressure warning indica-tors are of the "doll's-eye" type. Two V.H.F. sets are fitted. Three cartridges are provided for engine starting and canrapidly be replaced. Take-off is reported to require between 10 Test pilot Sonderman. A photograph of the Hunter is on p. 605. and 15 sec and undercarriage retraction 6 sec. Climbing speed isquoted as 0.87 Mach, with a cruising speed in the region of 0.92 Mach. Fully powered aileron control allows a rate of roll in theregion of 300 deg/sec, which is close to the human tolerance for such a manoeuvre. The elevators are servo-assisted and there is,therefore, a feedback of aerodynamic loads, but the effect can be alleviated by making use of an electric stick-top trimmer. Maxi-mum speed for undercarriage extension is 230 kt and approach speed is quoted as 20 per cent higher that that of the Meteor. The Wilbur Wright Lecture—and R.Ae.S. Awards "PLIGHT CONTROL" in theory and practice will form the*- subject of the Royal Aeronautical Society's 43rd Wilbur Wright Memorial Lecture, to be given on May 19th by Dr. C. S.Draper, F.I.A.S., head of the Department of Aeronautical Engineering at the Massachusetts Institute of Technology. Dr. Draper has written extensively in the fields of instrumenta-tion and control, and is a well-known consulting engineer. Since 1922 Dr. Draper has been continuously at M.I.T.,becoming Professor of Aeronautical Engineering in 1939 and head of the department in 1951. In 1946 he received the Medalfor Merit and the Naval Ordnance Development Award for his war-time work in anti-aircraft fire control, and among his otherdistinguished awards are the Sylvanus Albert Reed Award of the Institute of the Aeronautical Sciences and the ExceptionalCivilian Service Award made by the Department of the Air Force. As is customary on the occasion of the Wilbur Wright Lecture,the Royal Aeronautical Society's awards will be presented. The R.Ae.S. Gold Medal—the highest honour which the Society canconfer in recognition of scientific achievement in aeronautics— is being awarded to Lord Hives (chairman and joint managingdirector of Rolls-Royce, Ltd.) "for his outstanding work in the field of aircraft propulsion." Recipients of other medals awarded will be as follows: —The Society's Silver Medal (for work of an outstanding nature in aeronautics).—Dr. R. A. Frazer, for his outstanding work in aero-dynamics over a period of many years; and Dr. A. A. Griffith, for his outstanding research contributions on aircraft engine design. TheSociety's Bronze Medal (for work leading to an advance in aeronautics). —Professor M. J. Lighthill, for his contributions to aeronautical know-ledge. The Wakefield Gold Medal (for the designer or inventor of any apparatus tending towards safety in flying).—Mr. J. Taylor, for thedesign and development of the counting accelerometer. British Gold Medal (for outstanding practical achievement leading to advancementin aeronautics).—Mr. G. H. Dowty, for his outstanding practical achievement in the design and development of aircraft accessorysystems. British Silver Medal (for practical achievement leading to advancement in aeronautics).—Dr. S. G. Hooker, for his practicalachievement in the design and development on aero engines. George Taylor (of Australia) Gold Medal (for the most valuable R.Ae.S. paperon aircraft design, manufacture or operation).—Mr. R. C. Morgan, for his paper on Practical Experience of Airline Engineering. SimmsGold Medal (for the most valuable R.Ae.S. paper on any subject allied to aeronautics).—Dr. D. Williams, for his paper on Recent Develop-ments in the Structural Approach to Aeroelastic Problems. As recorded in Flight last week, Honorary Fellowships havebeen awarded to Mr. Igor Sikorsky and Mr. H. Grinsted. On the occasion of the presentation, at the Society's annual generalmeeting on May 5th, the following awards were also made:— R. P. Alston Memorial Prize (for practical achievement associatedwith the flight-testing of aircraft).—G. A. V. Tyson, for his contribu- tions to the flight testing of marine aircraft. Edward Busk MemorialPrize (for the most valuable R.Ae.S. paper on applied aerodynamics).— J. C. Wimpenny, for his paper on Stability and Control in AircraftDesign. Herbert Akroyd Stuart Memorial Prize (for the most valuable contribution on applied thermodynamics).—E. E. Chatterton, for hispaper on Compound Diesel Engines for Aircraft. Usborne Memorial Prize (for the best contribution by a graduate or student on some subjectof a technical nature in connection with aeronautics).—L. F. Crabtree, for his paper on The Compressible Laminar Boundary Layer on a YawedInfinite Wing. Orville Wright Prize (for the best contributions to the Aeronautical Quarterly of the Society).—D. B. Spalding and B. S. Tall,for their paper on Flame Stabilization in High Velocity Gas Streams and the Effect of Heat Losses at Low Pressures. J. E. Hodgson Prize(for the best paper of a general nature, with emphasis on historical work). —Maj. G. P. Bulman, for the First Barawell Memorial Lecture; andJ. Smith, for the First Mitchell Memorial Lecture. Royal Aeronautical Society Navigation Prize (for the best paper onnavigation, including meteorological instruments and test equipment). —J. F. W. Mercer, for his paper on A Quantitative Study of InstrumentApproach. R.38 Memorial Fund. Two awards from the R.38 Memorial Fund were made, to Lord Ventry (to assist him in his experimentsand to help in the development of the airship Bournemouth), and to Mr. W. N. Alcock (to assist him in further investigations in connectionwith airships). Finally, the Society has announced the election of twenty-twoFellows, whose names we hope to list in a forthcoming issue. Below (left to right), Sir Sydney Camm, the retiring president, presents Honorary Fellowships to Mr. Sikorsky and Mr. Grinsted, the R. P. Alston Memorial Prize to Mr. Tyson, and R.38 Memorial Fund awards to Lord Ventry and Mr. Alcock. On the right, Mr. E. J. Mann (right), secretary of the Hatfield Branch, presents a silver salver to Mr. N. E. Rowe, the new president, as a token of apprecia- tion of his previous work, as chair- man of the branches committee, for the 25 R.Ae.S. branches. "Flight" photographs
