EDITORIAL COMMENT JYCLOGIRO " is the name given by H the American National Advisory Committee for Aeronautics to a type of aircraft in which the lifting surfaces are placed with their spans at right-angles to the line of flight, while following a circular flight path when the machine has no transla- tional velocity i.e., is stationary), but follow a cycloidal path when the aircraft, as a whole, is moving in any direction. We referred to the Rohr- " Autogiro" bach ''' Paddle Plane " in these or columns, and also published last week "Cyclogiro"? the first instalment of an article by Mr. W. S. Shackleton on this machine. In this week's issue Mr. Shackleton concludes his article. The fact that elsewhere in FLIGHT we publish this week some photographs and notes on the latest Cierva Autogiro, which will be known as the C.30 P and is the first of the production models, must inevitablv cause the serious student of aeronautics to ask him self which of the two types should be regarded as the aircraft of the future? The theory of both the autogiro and the cyclogiro is so complicated that few people in any country are qualified to express an opinion on the theoretical merits of the two types. Mr. de la Cierva has been working on the autogiro for very many years, and not until now has he evolved a type which meets the needs of the ordinary owner to his satisfaction. One may, therefore, well ask how long it is likely to take to bring the cyclogiro to a similar stage of perfection, quite apart from any relative merits of the aerodynamic features. The new C.30 P autogiro is a perfectly amazing aircraft. It takes off with almost no run, and lands without any run at all. Its climbing angle is good, it will remain in the air at speeds certainly as low as 20 m.p.h., and its cruising speed is probably well above 100 m.p.h. One could not really ask very much more from any aircraft. It will not, of course, hover stationary over the ground in a flat calm, nor will it rise quite vertically unless there is a fairly strong wind blowing. But it may well be argued B
