- Company Profile:
A maintenance procedure in which the fuel control on a gas turbine engine is adjusted to cause the engine to produce the required EGT or EPR at a specified rpm.
Industry:Aviation
A maintenance program that closely monitors the operating condition of an engine and allows major repairs or replacements to be made when engine performance deteriorates to a specific level.
Industry:Aviation
A measure of change in viscosity of an oil as it changes temperature. The higher the viscosity index, the less the viscosity changes.
Industry:Aviation
A measure of efficiency of a turbojet or turbofan engine. It is a measure of the number of pounds of fuel burned per hour for each pound of thrust produced.
Industry:Aviation
A measure of rotational speed. One rpm is one revolution made in one minute.
Industry:Aviation
A measure of the amount a shaft, flange, or disk is bent or fails to run true. Runout is normally measured with a dial indicator.
Industry:Aviation
A measure of the amount of fuel used for a given amount of power produced by a heat engine. BSFC is expressed in pounds of fuel burned per hour for each brake horse-power the engine is producing.
Industry:Aviation
A measure of the effectiveness with which an aircraft engine converts the fuel it burns into useful thrust. It is the ratio of the thrust horsepower produced by a propeller to the torque horsepower of the shaft turning the propeller. The nearer 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.
Industry:Aviation
A measure of the loss of strength of a material caused by the presence of a notch, or a V-shaped cut.
