Abstract
A method for loading a plastic bonded explosive by the use of ultrasonic rations and moderate pressure.
Claims9
A method for loading extrudable plastic bonded explosives into long small diameter orifices contained in a warhead initiation system comprising pressurizing the loading system with an inert gas at pressures in the range of 1000 to 2000 psi and providing ultrasonic vibrations on the loading system in the range of from 20K H.sub.z to 30K H.sub.z.
Apparatus for ultrasonic loading of extrudable plastic bonded explosive into a warhead initiator comprising in combination, an ultrasonic transducer, an extrusion nozzle, a curved coupler exponential horn, an extrusion cavity, an adapter, a preloaded hydrostatic chamber for loading a plastic explosive composition into the extruder and means to supply pressurized gas at pressures from 1,000 to 2,000 psi to the extrusion cavity.
