As seen in this film, rapid development of aircraft design in the 1930s required many related innovations, including propeller design. The hydromatic propeller by Hamilton Standard marked a significant advance over the counterweight-type, controllable pitch propeller. It played a distinguished role in allied combat aircraft in World War II. Its continuing development has incorporated many features used on later aircraft, including today's turboprop planes.
The hydromatic propeller was designed for larger blades, faster rate of pitch change, and wider range of pitch control than earlier controllable-pitch propellers. Improvements from a two-position controllable to the constant- speed type propeller were not equal to the demand of high-output engines or rapid airplane maneuvers. The variable-pitch aircraft propeller allowed the adjustment in flight of blade pitch, making optimal use of the engine's power under varying flight conditions. On multi-engined aircraft it also permits feathering the propeller--stopping its rotation--of a nonfunctioning engine to reduce drag and vibration.
