Apparatus and methods for controlling yaw of a rotorcraft in the event of one or both of low airspeed and engine failure are disclosed. A yaw propulsion provides a yaw moment at low speeds. The yaw propulsion device may be an air jet or a fan. A pneumatic fan may be driven by compressed air released into a channel surrounding an outer portion of the fan. The fan may be driven by hydraulic power. Power for the yaw propulsion device and other system may be provided by a hydraulic pump and/or generator engaging the rotor. Low speed yaw control may be provid...


1. A rotorcraft comprising: an airframe including a cabin portion supporting flight controls and a seat to receive a pilot,a tower portion fixed to the cabin portion and extending upward therefrom,an empennage extending from the cabin portion away therefrom,a first vertical stabilizer mounted to the empennage,a first rudder secured to pivot with respect to the first vertical stabilizer, anda horizontal stabilizer connected to the empennage;a rotor rotatably mounted to the tower to rotate about an axis of rotation offset from the first vertical stabilizer...
