PRINCIPLES OF MECHANISMS USED IN CONTROLLABLE PITCH PROPELLERS

A controllable pitch propeller has a central hub which serves not only for the attachment of the blades but also contains the mechanical components to make the blades rotate. Inside the hub a translation motion is transformed into rotation of the blades. This involves large actuating forces, some times amounting to three times the total thrust on the propeller. Various types of blade suspension systems are described. The principles of crank-conrod, crack-slot, slot-pin and double-acting mechanisms are discussed in relation to their historical origin and development to modern conceptions. It is concluded that a sliding slot mechanisms with slots in the rotating parts has favorable characteristics for application in normal and feathering propellers.
