propulsive efficiency

propulsive efficiency

A measure of the effectiveness with which an aircraft engine converts the fuel it burns into useful thrust, and is the ratio of the thrust horsepower produced by a propeller to the torque horsepower of the shaft turning the propeller.

The more nearly the speed of the aircraft is to the speed of the exhaust jet or propeller wake, the less kinetic energy is lost in the jet or wake, and the higher the propulsive efficiency.
