Abstract
The invention relates to a rotorcraft (10) having a main rotor (11), a turbine engine (13), and a transmission mechanism (MGB) coupled to the rotor and to the engine to enable the engine to drive the rotor. The engine has a free turbine (132) connected to the transmission mechanism (MGB) by a shaft (15, 15a, 15b, 16, 18). The rotorcraft includes an external compressor (19) arranged to be driven by the free turbine (132) or by an electric motor, together with an air-transport duct (21) connecting the external compressor (19) to the engine so as to deliver the air that has been compressed by the external compressor to the inlets (22) of the engine.
