172 FLIGHT. FEBRUARY 14, 1935 MORE About the "SNARK" Some Performance Figures for Dr. N. de Bruyne's Design : Practical Details The "Snark," photographed on Marshall's aerodrome at Cambridge. which means that the machine, although a comparatively small wooden cantilever monoplane, carries 82 per cent, of its gross weight—an unusually high figure for this class of machine. This has been achieved, as was explained in Flighl of December 27, 1934, D>' the evolution of a system of stress ing which takes into full account that proportion of the stress carried by the plywood skin, both of the fuselage and the wings. The '' Snark '' embodies a number of very interesting points, quite apart from its main structural features. The control column is of the jointed type, so that the top can be swung over to allow either front passenger to fly the machine. On the rear of the top of this column is another small handle which operates the brakes; a sideways motion brakes either wheel for taxing, while pulling backwards puts on both brakes together. This last point is valuable, in that it ensures raising the elevators at the same time that the brakes are applied. This brake lever can also be locked in the fully-on position for parking, locking the elevators at the same time; and, as the ailerons are operated by an irreversible link motion, the machine is then in a suitable state to be left unattended. Data are as follows:— WEIGHTS:—Weight empty (excluding upholstery). 1,180 lb.; all-up weight, 2,200 lb.; wing-loading, 9.3 lb./sq. ft.; power loading, 16.9 lb./h.p.; weight/span, 1.24 lb./sq. ft. AREAS (sq. ft.):—Wing, 216.4; ailerons, 21.6; tailplane, 16.4; ele vators, 10.4; rudder, 6.6; fin, 6.7. PERFORMANCE (estimated):—max. speed, 120 m.p.h.; cruising speed, 112 m.p.h.; landing speed, 40 m.p.h.; initial rate 0! climb, 600 ft./min.; ceiling, 15,500 ft.; range, 500 miles. Death of J. J. A. Qilmore It is with deep regret that Flight has to record the death of Mr. J. J. A. Gilmore, of the Directorate of Aeronautical Inspection, at the age of 45. Although he had not been in very good health for some time, his death occurred with almost tragic suddenness on February 1. " John," as he was affectionately known to all his colleagues and friends, was a man of likeable personality, always willing to listen to other people's troubles and always ready with advice. His ready Irish wit was much appreciated, and at the annual dinners of the A.I.D. Technical Staff Association, of which he was the first chairman, an office which he filled with distinction up to the time of his death, hosts and guests alike looked forward to his speeches. Mr. Gilmore entered the A.I.D. in 1916 as an examiner, and had attained, a few days before his death, promotion to the rank of Assistant Chief Inspector of Materials. His death is a great loss not only to the A.I.D. but to the aircraft industry generally. An Important Sheffield Merger The electro-metallurgical, electro-chemical and other indus tries of Great Britain have for years been dependent on sup plies of graphite and graphite electrodes from abroad. Now comes news that these products will shortly be manufactured in England. A merger has taken place between the Electrode Co., of Sheffield, Ltd., producers of amorphous carbon elec trodes, and the Acheson Graphite Corporation of New York, for years the leading suppliers of graphite electrodes to the FOUR seats, and a range of 500 miles, is a good perform ance with a "Gipsy Major " when the cruising speed is 112 m.p.h. The "Snark," designed by Dr. N. de Bruyne, of Aero Research, Ltd... Cambridge, is capable of achieving these figures, and it is probable that after further tests the all-up weight will be increased. Even at its present figure the ratio of gross weight to tare weight is as high as 1.82, The cabin top is hinged on radius rods, which lift it as it is moved back; the difficulties of sliding the roof in grooves are thus avoided. English markets, resulting in the formation of British Acheson Electrodes, Ltd., which company will manufacture and sell both carbon and graphite electrodes as well as graphite powders. The chairman of the new organisation is Mr. C. W, Kayser, of Kayser, Ellison and Co., Ltd. War Birds at Dinner A large number of war-time pilots gathered together for dinner at the Criterion Restaurant, London, last Saturday The guest of the evening was A.V.-M. C. Courtney, who assured his audience that the Air Ministry was doing its utmost to repair the ravages caused to the Royal Air Force by the last ten years' retrenchment. Replying to those who hop™ that the expansion would be rapid, he said that they must build on a base as well established as the original conception Things which are unduly hurriedly built up, he said, usually fall down. Examinations for Q.E. Licence Applicants An Air Ministry Notice to Aircraft Owners and Ground Lag*" neers gives dates at which boards will sit for examining apP cants for G.E. licences, as follows:—London, weekly, on ea Tuesday in April, May and June; Croydon, on the seco Friday in April, May and June, 1935; Manchester, on ^aen Friday in June; Bristol, on the first Friday in April; Glasg on the first Thursday in May, 1935. ^, Application forms and full details are obtainable from Secretary, Air Ministry (C.A.2), Adastral House, KingsvW' London, W.C.2.
