Techniques for Measuring Burn Times for M864 Base-Burn Projectiles

Abstract

Techniques using telemetry and Doppler radar were used to obtain measurements of the burn time of the propellant in the 155mm M864 base-burn projectile system. The telemetry technique used a simple radio frequency transmitter which was mounted in the fuze well of the projectile burn-out. The radar technique compared discriminated Doppler radar data for a projectile without propellant to that of a projectile with propellant. Two firing programs were conducted at Aberdeen Proving Ground. A total of 18 rounds were fired with different Mach numbers and quadrant elevations. Data from these firings indicate that the burn-out time varies significantly with quadrant elevation. Temperature conditioning the propellant grain with dry ice (-78 degrees centigrade) increased the burn-time.
