Method for boosting a turbofan engine

Abstract

The invention relates to turbofan engines. A method for boosting a turbofan engine consists in increasing the volume of air fed by a fan of the engine into both the core and the bypass duct by briefly activating a brushless electric starter, thereby increasing the rotor speed of the turbofan engine by 5-10% for 10-30 seconds, with a simultaneous proportional increase in the amount of fuel fed into the combustion chamber of the engine. The method makes it possible to briefly increase thrust performance during the takeoff of an aircraft or during an aerial manoeuvre, without increasing the specific weight of the turbofan engine.
