figgj] CORRESPONDENCE. The Kite and Model Aeroplane Association. 1711] The recent growth of aviation has caused an ever- increasing amount of attention to be directed to the important •cientific work and experiments that yet remain to be carried out in -order to place the British aeronautical industry on a footing that will enable it to meet on level terms the industries that have been established abroad, and in many cases fostered directly by State subsidies. In developing its industries, this country has always relied chiefly on private effort and endeavour. Expert opinion is unanimous in the view that scientific and technical progress can best be achieved by means of experiments with models. Model flying is by no means simply a sport or pastime ; in many respects it has become a science, fraught with great possibilities for the development of the full-size machine for military and other purposes. Furthermore, it -forms an educational medium of the very highest value. It is on this basis that the Council of the Kite and Model Aero plane Association ventures to appeal to your readers to join the membership of this body. If the model aeroplane is to receive the support and widespread recognition that are essential for the proper future development of aviation in this country, it is nece'sary that its governing body should be strengthened as far as possible. The Kite and Model Aeroplane Association is recognised, by -agreement with the Royal Aero Club, as the governing British body in all matters pertaining to kites and model aeroplanes. For the past three years the association has carried out, at considerable expense, a series of competitions that have done much to foster model aeroplaning in this country. For the coming year an inter- 'national model competition, to be held in England this summer, is in process of organisation, in addition to a number of other national competitions. Furthermore, the Association has recently succeeded, with the approval of the War Office, in forming a Motor Man-lifting Kite and Wireless Corps (the War Kite Squadron) to be run in conjunction with the Territorial Army. Dona'ions to this patriotic object are urgently needed. In order to pursue its work, which, as you will see, is in great •part national in its nature, the Association appeals to all those who have the development of aeronautics at heart to join its membership and strengthen its hands and also give or obtain the gift of prizes. A leaflet setting forth briefly the objects and activity of the Kite and Model Aeroplane Association, together with an application form for membership, will we forwarded on application to W. H. AKEHURST, Hon Secretary, The Kite and Model Aeroplane Association. 27, Victory Road, Wimbledon. Colllndale Avenue. [1712] As an ardent motor cyclist and a lover of aviation I venture to ask you if you can tell me whether any of us will live to see Collindale Avenue repaired. For the past few months it has been in a perfectly abominable state, but yesterday it represented a perfect bog. Crowds of jeering people stood at the corner of the road (?) to watch my friend and myself (both on motor cycles) ride towards the aerodrome, and it was only our contempt for their remarks which made us stick to our task. I am unaware whose business it is to keep this road in proper condition, but when motor cyclists or even motorists coming to see the flying are confronted with such a horrible mess, it makes them think twice before they venture across it. TEETEEIST. The Collapse of Monoplane Wings. [1713] I was very pleased to see Mr. Howard Flanders' reply to my remarks on the question of the collapse of monoplane wings, because, however much we may differ, it is by these very differences that goxl may result from the discussion. Mr. Flanders' remarks, however, valuable as they undoubtedly are, loss much of their emphasis from the fact of his having missed the point of my argument, viz : that it is possible for the ends of the wings both to twist in the same direction and to be resisted in their twisting by the body portion of the machine. In the con ditions assumed in my argument, one plane does not increase in angle while the other decreases in angle, and the attitude of the machine to the horizon has no relation to the question. The suggested experiment of the stone placed on the passengers' seat, which would leave the seat on top-pressure occurring, has no bearing on the proposition, because the strains and breaking effect suggested in my article do not necessarily involve descent at all, prior to the actual collapie of the wings. I fully appreciate that JANUARY 25, 1913 the upper bracing should not be slack, that the pilot has instruments, and that the maker braces the wings to guird against all the strains he can calculate or imagine, but without being a maker, designer or mathematician, one can still realise that there exists some force hitherto unrecognised, and consequently unguarded against, for in spite of all Mr. Flanders tells us, monoplane wings do occasionally collapse downwards. It is therefore the duty of all who are interested in aviation, to suggest any thought which, if not the whole reason or a full explanation, may prove a clue to this unexplained danger. Hence my temerity in offering a modicum to the theory of aviation. GRIFFITH BREWER. ® ® ® ® PUBLICATIONS RECEIVED. Les Hydro-Aeroplanes. By P. Riviere. Preface by A. Tellier.
