Ground Testing for Base-Burn Projectile Systems
Abstract
A ground test spin fixture was used to obtain measurements in the base region of a 155mm M864 projectile. The M864 uses the base burn concept of reducing base drag by injecting gas, generated b burning propellant, into the base area. Pressure and temperature measurements were obtained in the base area of the projectile, with the base burn active, at spin rates up to 250 rps. Data illustrate that increased spin rate increases the pressure in the propellant chamber and increases substantially the burning rate of the propellant . The ground tests provided information on measurement techniques which will be used in free-flight experiments. Base burn, Ignition, Spin fixture, Projectiles, Chamber pressure.
