<p>A nose assembly (26) and method for controlling the rotation and stabilizing the orientation of a vehicle (10) during landing maneuvers. The vehicle (10) includes a nose assembly (26). The vehicle flap assembly (30) includes an actuator (32) and a flap (38a) from and between a fully retracted position and a fully extended position in response to a guidance signal received from a flight control computer. In a preferred embodiment, the flap assembly (30) includes a plurality of flaps (38a-38c) each coupled to the nose assembly frame (26) and an actuator that selectively positions the plurality of flaps (38a-38c) in response to a signal. The method for rotating a vehicle (10) in nose-forward flight, rotating the vehicle (10) in a first direction, and selectively actuating one of a first and second flaps (38a-38c) from a retracted position toward an extended position to generate a damping moment tending to position the vehicle (10) in a base-forward orientation.</p> |
