Tail rotor assembly for helicopter to generate power thrust for compensating turning moment generated by main rotor of helicopter, has tail rotor with multiple rotor blades arranged in rotatable rotor spindle

摘要

The tail rotor assembly (1) has a tail rotor (2) with multiple rotor blades (3) arranged in a rotatable rotor spindle (4). A tail rotor drive is provided for driving the tail rotor in a rotary manner for generating the power thrust. The tail rotor drive has an electric motor (10) and another electric motor (20) separated from the former electric motor to form a redundant drive trains. The former electric motor is connected with the rotor spindle of the tail rotor for rotationally driving the tail rotor.
