FLIGHT, JUNE 28, 1934 HtV\ No. 14 : Handley Page " Heyford," Mark II (two Rolls-Royce " Kestrel " engines). (FLIGHT Photo.) No. 15 : Cierva " Autogiro " (Armstrong-Siddeley " Civet " engine). (FLIGHT Photo.) Siddeley " Civet " engine, civilly known as the 140-h.p. 7-cyl. " Genet Major." Most readers of FLIGHT will be aware by now that the Autogiro depends for its lift upon the rotation of its " windmill " blades. These blades are not driven by the engine (except for the initial start- ing before a flight), but are kept rotating by the air forces upon them. The rotor blades have a diameter of 37 ft. The machine to be shown at Hendon has no fixed wing and no tail control surfaces. All manoeuvres, such as rising, descending, and turning, are carried out by tilting the head of the rotor, which has universal joints. The speed range in level flight is from 15 to 115 m.p.h. " Cloud " have for No. 16 Saro Saunders-Roe, Ltd., of Cowes, hav a number ofyears specialised on the design and construction of flying boats and amphibian flying boats. The " Cloud " whichwill be seen in the Display differs from the standard machine in that it has a monospar wing instead of theusual two-spar plywood-covered wing. The main feature of this wing design is that the single spar is placed as nearas possible to the centre of pressure position, and the wing is prevented from twisting by a system of wire or tie-rodbracing which forms two spirals. Two Siddeley " Serval " engines of 340 h.p. each are fitted. The wing span is 68 ft. No. 16 : Saro " Monospar Cloud " (two Armstrong-Siddeley " Serval " engines). 637
