Rotary wing aircraft provided with a rear rotor, and method for optimising the operation of a rear rotor

摘要

The aircraft (1) has a control unit (30) for controlling a pitch modification device (20), and an electric motor (9) for rotating a rear rotor (5). A regulation unit (TRCU) is connected to the electric motor and the pitch modification device by the control unit. The regulation unit provides a pitch instruction transmitted to the pitch modification device, and an engine parameter control instruction transmitted to the electric motor. An electric generator (7) is electrically connected to a power transmission gear box (3) for supplying power to the electric motor. An independent claim is also included for a method for optimizing an operation of a rear rotor of an aircraft.
