Abstract
In this report, the process characteristic(viscosity), mechanical properties, combustion characteristics, ground and flight test results of propellants used for a rocket-assisted projectile are described according to several aluminum contents. As the aluminum content increased, initial viscosity decreased, viscosity build-up accelerated, and combustion rate and pressure exponent decreased. In the ground fire test, the total impulse of the rocket-assisted projectiles containing 10 wt% of aluminum were 5% higher than that of the rocket-assisted projectiles containing 2 wt% and 18 wt% of aluminum. The motor efficiency compared to the theoretical performance was 85.6% with 18 wt% of aluminum, the lowest value among the propellant compositions.
