Title:
AIRCRAFT FLIGHT TERMINATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2009/134513
Kind Code:
A3
Abstract:
An aircraft (10) has a flight termination system (12) that allows flight of an unmanned aircraft to be quickly and efficiently terminated. The flight termination system separates one of the control surfaces (20) of the aircraft, such as a wing (32), from a fuselage (14) of the aircraft, while one or more other control surfaces connected to the fuselage. The separation may be accomplished by firing one or more explosive bolts to release a clamp that connects the control surface to the fuselage. The separation causes an asymmetry in configuration that results in a rapid crash of the aircraft. The flight termination system causes termination to be effected in small flight footprint, without use of powerful explosives, and without a large cost in weight or volume. The flight termination system may be used in unpowered or powered aircraft.
