METHOD AND DEVICE FOR PROJECTION OF SOLID BODY Russian patent published in 2000 - IPC

FIELD: military equipment, in particular, smoothbore and rifle artillery, as well as small arms. SUBSTANCE: translational motion in the bore is imparted to the solid body under the action of the live charge. Just before the beginning of translational motion of the solid body and in the process of the above motion ultrasonic oscillations are set up in the barrel walls. The device for projection of solid body has a barrel with a bore and projected body with a live charge, as well as an ultrasonic generator comprising a magnetostriction transducer coupled to the barrel via an acoustic concentrator. EFFECT: enhanced initial speed of projected body translational motion, range and accuracy of fire, enhanced barrel survivability. 2 cl, 2 dwg
