DEVELOPMENT OF VIBRATION RESISTANT PROPELLANTS FOR THE M91 PAD CARTRIDGE. INTEGRATED MOLDED CHARGE
Abstract
A case bonded, integrated, molded propellant charge (consisting of RDX-cellulose acetate) was developed which met the ballistic requirements for the M91 PAD cartridge and which provided high resistance to both vibration and temperature. The charge consisted of small granulation propellant molded into a monoperforated cylinder which was bonded to the case. The required black powder was sealed in the perforation by means of an adhesive cellophane disc affixed to the top surface of the molded charge. Thermal stability tests revealed the cartridge to be substantially superior to cartridges containing the nitrate ester single base propellant previously used and similar to the ammonium perchlorate-cellulose acetate (HES 5808.7) propellant currently used as the standard. Neither the physical nor ballistic properties of the experimental cartridges were affected by severe vibration. While the same vibration caused no change in the ballistic performance of the standard cartridge, pulverization and subsequent deposition of the black powder on the surface of the loose propellant grains was found to occur.
