<p>The installation (10) has a tail gearbox (BTA) driving an anti-torque rotor (4) of a helicopter (1). Electric motors i.e. brushless motors, are mechanically connected to a main gearbox (BTP) to drive the main gearbox and connected to the tail gearbox to drive the tail gearbox. An engine e.g. piston engine, is connected to the main gearbox by a shaft. The tail gearbox is connected via another shaft to the engine or to the main gearbox. Maximum electric power of the electric motor is equal to percentage of a product of nominal speed of rotation multiplied by torque limit. An independent claim is also included for a method for driving a rotary wing and an anti-torque rotor of a helicopter.</p> |
