Abstract
For enhancing the maneuverability, speed, survivalbility, and targeting accuracy of a torpedo moving below the surface of a body of water, ultrasonic vibrations are set-up at the exterior of the torpedo hull, using controlled piezoelectric crystals to generate the vibrations in the 5-50 KHZ and 5-30 KW frequency and power ranges. Ways are disclosed for operating the piezoelectric crystals to steer the hull without need for mechanically moving parts such as flaps or fins.
