Apparatus and methods is used for controlling yaw of a rotorcraft in the event of one or both of low airspeed and engine failure. 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 provided by ...


1. A rotorcraft comprising: an airframe;an engine connected to drive the rotorcraft through the air;a rotor rotatably mounted to the airframe and rotatable about an axis of rotation;a power take-off selectively uncoupling from the rotor and coupling to the rotor to be driven by the rotor, the power take-off including a drive wheel; anda power source connected to receive power through the power take-off and comprising at least one of a hydraulic pump and a generator;a mast extending upward;a shroud surrounding the mast and being fastened to the mast;a fla...
