Abstract
Abstract An apparatus and method for reducing the launch disturbance of a weapon se on a supersonic aircraft is disclosed. The apparatus comprises a flywheel rotatably mounted within the store. The flywheel is pre-spun before launch using internal rockets or ram air. The spining flywheel produces a gyroscopic effect which appreciably reduces launch disturbance and therefore increases accuracy.

Claim 1
Independent Claim
99 words
A nonself-propelling finless bomb adapted to be carried on and launched from aircraft at supersonic speeds comprising: a casing having suspension means thereon for mounting the bomb on the aircraft; an explosive warhead disposed within said casing; a flywheel fixed to a shaft mounted for rotation within said casing on the longitudinal axis thereof; and means for imparting rotation to said flywheel prior to launch whereby the angular momentum of the bomb is substantially increased, and its maximum angle of attack due to an angular rate correspondingly reduced, to minimize launch disturbances when the bomb separates from the aircraft.
