20250215824. Improved Propulsion (SAFRAN HELICOPTER ENGINES)
IMPROVED PROPULSION ASSEMBLY FOR MULTI-ENGINE HYBRID AIRCRAFT
Abstract: a propulsion assembly for a hybrid aircraft including a first and a second engine each having a gas generator and a free turbine, a main rotor coupled to the free turbine of the first and second engines, the first engine including a first electric machine and a second electric machine of lower power than the first electric machine, one of the first or of the second electric machine being able to be coupled to the gas generator and to set the gas generator in rotation during a start phase of the engine, and being further able to be coupled to the free turbine in order to generate electrical energy after the start phase, the other of the first or of the second electric machine being coupled to the gas generator only.
