Propellers are primarily divided into fixed-pitch, which offer a compromise between climb and cruise performance, and various adjustable-pitch types for optimized flight across different conditions.

Stopping a massive ship in an emergency is far more complicated than just throwing it in reverse, and the answer depends entirely on what kind of propeller and engine you're working with. From steam ...
This propeller was designed by the U.S. National Advisory Committee for Aeronautics (i.e. NASA’s predecessor) to reduce noise in light airplanes. The investigation was undertaken as an aid to the ...
