초록

The present document describes a yaw control system for a helicopter having a controllable aft rudder. The system comprises a fan for blowing low pressure air impinging upon the controllable aft rudder. During flight, the main rotor assembly drives the fan and the air flow impinging upon the controllable aft rudder creates a side force which enables yaw control.

청구항

1. A yaw control system for a helicopter having a controllable aft rudder, an engine and a main rotor assembly, the yaw control system comprising: a low pressure fan for producing a low pressure air flow impinging upon the controllable aft rudder, the low pressure fan being mechanically connected to the main rotor assembly;wherein during flight, the main rotor assembly drives the low pressure fan without a direct load path from the engine to the low pressure fan and the low pressure air flow impinging upon the controllable aft rudder creates a side force...
