SOCIETY OF MODEL AERONAUTICAL ENGINEERS (London Aero-Models Association). "Flight" Cup Competition THE weight-lifting competition for the FUGHT Challenge Cup was held on the Sudbury flying ground on Saturday, October 18. The weather conditions were ideal, and good flights were obtained. The minimum weight of the models allowed was 10 oz., whilst the dead load carried had to be a quarter of the weight of the model (unloaded). The winning flight was made by Mr. S. C. Hersom (the previous holder of the Cup) with a duration of 26 sees., Mr. B, K. Johnson being second. Thus Mr. Hersom maintains his hold on the Cup for another year. Result of the S.M.A.E. Research Competition for Self- Righting Model Aeroplanes MORE than twenty members of the S.M.A.E. assembled at Sudbury Hill on Saturday, October 18, for this Competition, the rules and conditions of which were published early in the season. Six models were eligible to compete, and all of these passed the test of gliding by hand launching before being hoisted up on the aerial specially designed and constructed for the purpose of releasing the models vertically downwards. Only one model recovered flying equilibrium without stalling afterwards. This was a Dunn type monoplane, constructed by Mr. B. K. Johnson. His machine got out of the vertical dive in approximately 10 times the length of the model, and then glided to earth steadily at a reasonably good angle. This performance was repeated at least a dozen times with exactly the same result each time. Mr. B. K. Johnson, therefore, wins the first prize of two guineas, offered by the Research Committee of the above Society, for a model of an aeroplane which, having the requisite factor of safety cannot fall vertically to earth after stalling at a certain low altitude, which in this case represents about 10 times the length of the model. Mr. L. G. Tucker's model was an ordinary fuselage mono plane, having balanced elevators, controlled by a pendulum device inside the fuselage. This was the only model which had an automatic stabilising device, and was untried before the competition. Mr. Tucker was unable to prevent the model stalling after the dive, but members present were of opinion this could be overcome by fitting slightly larger elevators for quicker recovery and some adjustment of the controlling gear to prevent over-elevation after regaining equilibrium. Messrs. Lansdown, Sherwen, Green, and Hersom all, unfortunately, killed their pilots several times over. The second and third prizes not being won are held over for a future competition, Details of Mr. B. K. Johnson's model Dunn type monoplane, and of the releasing apt>aratus will be given at a future date. A. E. JONES, Hon. Sec. Aero Golfing Society THE Aero. Golfing Society held its Autumn Meeting at Moor Park, Rickmansworth, on October 23, when the following events were decided :—Autumn Challenge Cup (presented by Cellon, Ltd.). Result : Flight-Lieut. D. F. FitzGibbon, 80 less 3 = 77 ; H. Burroughes, 84 less 6 = 78 ; Sir Henry White Smith, 98 less 14 = 84. Bogey Four Ball Foursomes : Sir Henry White Smith and Maj. R. H. Mayo, 5 up ; Capt. W. Aston and Lieut.-Com. H. E. Perrin, 4 up; P. Barry and Col. C. Jarrott, 2 up ; Capt. L. V. Pearkes and Flight-Lieut. D. F. FitzGibbon, 2 up. A Bider Memorial A MONUMENT was unveiled at Berne on October 25, to the Swiss airman, Oscar Bider, who achieved fame by his flights over the Swiss mountains in 1913, and who lost his life flying at Diibendorff on July 7, 1919. m * SIDE-WIND OFFICERS in the Royal Air Force are being very thoroughly catered for in regard to usual outfit and full-dress wear by Burch's, 401, Strand. This firm has just sent us along a revised price list, from which we gather they have studied and brought the R.A.F. requirements down to a fine art. A special .offer is made to reserve officers, and any in this branch of the Service would do well, before going elsewhere, to visit Burch's. Included in this offer are the following :— Service jacket, Regulation breeches, Regulation service cap, and embroidered badge, shirt, collar and tie, R.A.F. puttees, and Decorations. Another of Buret's specialities comprises a full range of tropical outfits. PUBLICATIONS RECEIVED Report No. All. Meting van der den door Metaalgaas Veroorzaakten drukval in een Windstroom.
