- Definição2
- A type of propeller used on aircraft when low cost and simplicity are more important than efficient performance. The blades of a fixed-pitch propeller are set at one pitch angle which cannot be changed. Up through World War II, most fixed-pitch propellers were made of laminated birch, but since that time most have been made of forged aluminum alloy. The pitch angle of a fixed-pitch propeller is a compromise between that which allows the engine to turn fast enough to produce the maximum horsepower for takeoff, and that which moves the aircraft through the air a maximum distance for each revolution, giving the best fuel economy and speed.
