Mercury Racing has expanded the pitch range of its popular Revolution 4 XP propeller line, investing in a new base casting that will be used to produce this high‑performance prop in a 15‑inch diameter ...

Controllable-pitch propellers have been developed and produced on the Baltic coast of Germany since 1962 – initially in Rostock, and then in Wismar from 1964. The first units were manufactured for 86 ...

Propellers for piston-powered small airplanes primarily come in fixed-pitch, ground-adjustable, and constant-speed variants. Fixed-pitch propellers have a static blade angle, optimizing performance ...

Barring the smallest manned airplanes, most aircraft that are pulled around by a prop have variable pitch propellers. The reason for this is simple efficiency. Internal combustion engines are most ...

Quadcopters tend to have very poor efficency because of their high disk loading. High disk loading– that is, how much weight each square meter of area swept by the propellers must carry–is almost ...
