MECHANICAL BREACHING DEVICE

A MAN PORTABLE, NON-EXPLOSIVE BREACHING DEVICE IS PROPOSED TO GAIN ENTRY INTO BUILDINGS THROUGH WALLS, DOORS, ROOFS, ETC. THE PROPOSED INEXPENSIVE, LIGHTWEIGHT BREACHING DEVICE WILL USE AN INTEGRAL HIGH PERFORMANCE ROCKET MOTOR TO PROVIDE EXTREMELY HIGH FORCES FOR A FEW MILLISECONDS TO DRIVE A RAMMER PLATE OR CUTTING BLADE SET THROUGH THE DESIRED ENTRY POINT. THE COMBINATION OF HIGH FORCE BUT SHORT DURATION IS THE OPTIMUM METHOD OF PENETRATING AND CLEARING THE ENTRY POINT; THE PROPOSED FORCE GENERATOR CAN BE SIZED TO ACHIEVE THE DESIRED RESULTS FOR WIDELY VARYING OBSTACLES. WHILE THE ROCKET MOTOR WILL EMIT AN INTENSE NOISE FOR A FEW MILLISECONDS, THE MOTOR'S SOUND IS UNLIKE THAT OF AN EXPLOSIVE AND WILL SOON BE REPLACED BY THE SOUNDS OF THE ENTRY HOLE DEBRIS. THE ROCKET MOTOR FORCE GENERATOR IS AN ADAPTATION OF A HIGH ACCELERATION ANTI-TANK ROUND BEING DEVELOPED FOR DARPA TO PROVIDE HIGH PROJECTILE VELOCITIES IN VERY SHORT RANGES.
