Abstract
An inlet gas mixing element for a gas turbine engine, comprising a gas intake duct 10, and downstream of the inlet duct a mixing element 22, the mixing element being so disposed in relation to the inside of the duct so as to rotate thereby urging the forced mixing of the air and other gases moving past the element 22 towards the face of the fan blades of the downstream engine compressor stage 16. The action of the mixing element serves to increase the mixing of new air and other possibly hotter gasses so as to reduce the temperature differential across the face of the engine compressor stages.
