A propeller with variable pitch can have a nearly constant efficiency over a range of airspeeds. [1] A shallower angle of attack requires the least torque, but the highest RPM, because the propeller is not moving very much air with each revolution. This is similar to a car operating in low gear.

WebMay 17, 2003 · Constant-speed props are usually found on high-performance aircraft, but most people don't realize the concept of varying the pitch of a propeller was suggested 30 years before the Wright Brothers flew. John Ruley discusses the history, repair, and alternatives to this staple of aviation. WebThe propeller is a rotating airfoil, subject to induced drag, stalls, and other aerodynamic principles that apply to any airfoil. It provides the necessary thrust to pull, or in some cases push, the aircraft through the air. The engine power is used to rotate the propeller, which in turn generates thrust very similar to the manner in which a ...
