inlet guide vanes

inlet guide vanes

Stationary vanes located in front of the first stage of the compressor in an aircraft gas turbine engine. The purpose of the inlet guide vanes is to direct the air into the first stage of the compressor at the proper angle for the most efficient compression. Most inlet guide vanes are fixed, but in some engines, their angle can be changed by hydraulic actuators controlled by the fuel control unit. Movable guide vanes direct the air into the compressor at the correct angle as the operating conditions inside the engine change.
