Abstract : This report summarizes an eight-month program to develop a less complex and expensive 20mm incendiary projectile which is equal to or greater than the M56 A3/A4 HEI in incendiary effects against aircraft fuel cells. The approach consists of: EMPLOYING THE PYROPHORIC PROPERTIES OF MISCH METAL ALLOYS FOR INCENDIARY CAPABILITY; USING A PLASTIC JACKET FOR LOW COST AND LOW BARREL WEAR, AND ENVIRONMENTALLY SOUND ENCAPSULATION OF THE MISCH METAL CORE; OPTIMIZING MISCH METAL CORE MATERIAL AND CONFIGURATION WITH REGARD TO INCENDIARY EFFECTS AND BALLISTIC STABILITY; AND FABRICATING 1500 PROJECTILES OF THE FINAL DESIGN FOR FURTHER TEST AND EVALUATION (Author, modified-PL)
