DEVELOPMENT AND ENGINEERING TEST OF NEW COOL BURNING EXTRUDED AND ROLLED BALL TYPE PROPELLANTS FOR 20MM AIRCRAFT AMMUNITION.

Abstract

With respect to erosion characteristics the new single base extruded cool burning propellants (CR7787 and CR7814)IN Cartridge, Ball, 20mm, M55 with FAT27E1 primer are greatly superior to IMR7005 propellant and are superior to the previously developed single base cool burning propellant CR7695. Propellants CR7787 and CR7814 apparently meet all the requirements for 20mm aircraft ammunition. With respect to ero sion characteristics the new double base rolled ball propellant X2048, in Cartridge, Ball, 20mm, M55 with FAT FAT27E1 primer is superior to the standard ball propellant WC870. Propellant X2048 apparently meets all the requirements for 20mm aircraft ammuntion. The new primer FAT27E1 offers a substantial improvement in the ballistic charac teristics of 20mm ammunition with respect to high and low temperature firings. Primer FAT27E1 apparently meets all the requirements for 20mm aircraft ammunition.
