Abstract

THE originality of the Escher Wyss airscrew, which has been adopted by the Swiss Air Force, is based on the fact that its conception has, since its inception, taken into account all the requirements of a modern variable pitch airscrew. These conditions may be summarized as follows, that the airscrew must normally ensure automatic control at constant engine speed, adapting itself to every condition of flight, and that it should provide, when required, for operation as an aerodynamic brake, and be capable of being moved to the fully feathered position. The essentially mechanical problems, such as the anchorage of the blades in the hub and the design of the pitch control mechanism, must naturally find correct solutions to ensure reliability, together with that simplicity of control which is an essential property of all modern aircraft components.
