A 6-bladed Hamilton Standard 568F propeller on an ATR 72 short-haul airliner. Lowry [27] quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172.This is derived from his "Bootstrap approach" for analyzing the performance of light general aviation aircraft using fixed pitch or constant speed propellers.

An advanced type of propeller used on the American Los Angeles-class submarine as well as the German Type 212 submarine is called a skewback propeller. As in the scimitar blades used on some aircraft, the blade tips of a skewback propeller are swept back against the direction of rotation. In addition, the blades are tilted rearward along the ...

This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch. Most engines produce their maximum power in a narrow speed band. The CSU allows the engine to operate in its most economical range of rotational speeds , regardless of whether the aircraft is taking off or cruising.
