ABSTRACT:
A launch vehicle is deployed from an aircraft using gravity extraction of the launch vehicle with the aid of a small parachute which assists the extraction and damps the yaw and pitch of the launch vehicle. The launch vehicle is supported on two rows of tires which are rotatably mounted to the aircraft. Gravity and the drag force of the parachute causes the launch vehicle to roll on the tires along the load deck and out of the aircraft. Because the extraction forces are dominated by gravity, the launch vehicle acquires a rotation in the pitch axis as the launch vehicle leaves the aircraft. After the launch vehicle clears the aircraft, the launch vehicle rotates in the pitch plane, and is damped in the pitch plane by the parachute to a pitch attitude which is 70-80° and the vehicle engine is ignited, detaching the drag parachute.
