A projectile for a surface-to-surface weapon to combat a target from the top. The projectile includes a warhead; a propulsion system for accelerating the projectile directly after the projectile is placed in flight; a stabilizing guide assembly; a sensor for detecting a target in a longitudinal and lateral direction; and a pulse generator for turning the projectile about its center of gravity. The projectile additionally includes electronics for activating the warhead and for controlling the propulsion system and the pulse generator. A control unit rotates independently of the shaped charge warhead and houses the sensor, pulse generator and electronics. The pulse generator is arranged offset with respect to the sensor in the circumferential direction of the control unit. The electronics actuates the pulse generator in response to the sensor detecting a target, at a given distance ahead of such target, to produce a measured and radially directed control pulse to pivot the projectile so that it is aimed directly at the top of the target. The propulsion system additionally includes a drive assembly which is fired to accelerate the projectile toward a target, immediately after the projectile has been pivoted toward the target by the pulse generator. A mechanism is provided for preventing a restoring force generated by the ambient air from returning the projectile to the direction of flight existing prior to being pivoted.
A wall breaching warhead 10 for forming a hole through a brick wall includes a shaped charge 12 of explosive material having a central axis 14. The front surface of shaped charge 12 includes a central portion 16, adjacent to central axis 14, having a generally convexly-curved shape, and an annular portion 18, circumscribing central portion 16, having a generally concavely-curved shape. A metallic liner 20, adjacent to at least annular portion 18 of the front surface of charge 12.
The present invention relates to a method for attacking a target by means of a missile (1) with at least one shaped charge, the direction of action of which differs from the direction of flight of the missile, and to a missile (1) comprising at least one shape charge (2) arranged to act in a direction (4) that differs from the direction of flight (5) of the missile. The shaped charge jet is corrected for the speed of the missile (1). According to the invention, the correction of the shaped charge jet is adjustable, whereby the lethality of the missile can be achieved within a wide range of speeds of the missile.
A shaped charge engine includes an annular blast-forming chamber formed by joining inner and outer housings. A central through hole in the inner housing allows exhaust gases to exit. The outer housing comprises a generally round disk with an inner conical concave depression and through holes for the insertion of fuel and ignition. The blast chamber is preferably taper-conical in shape, wider at the base, and gradually decreasing in cross-sectional area as it rises to the apex. This construction forms a circular pinch point or throat toward the apex that produces a primary or first stage compression area. A secondary compression zone is created at the apex of the outer housing, just beyond the throat, producing hypersonic gases as generally opposing exhaust streams collide and are forced to exit the through hole in the inner housing. The shaped charge engine may be used in a variety of applications, including as a pulsed direct propulsion device, as a turbine driver, or in a wide array of tools and appliances.
