Abstract
A supercavitating underwater projectile adapted to be fired from a gun or the like, comprising a front end or nose portion and a rear end portion. An auxiliary rocket motor is disposed within the rear end portion of the projectile for providing additional thrust after the projectile has been fired. Vents are disposed within the projectile and are in communication with the rocket motor and the exterior of the projectile for venting some of the combustion gases from the rocket motor to the exterior of the projectile near the nose portion thereof to increase the size of the cavitation bubble formed as the projectile travels through the water and thereby reduce hydrodynamic drag on the projectile.
