Abstract:

A computer model was developed to simulate a projectile ram- propellant feed system for a Liquid Propellant Gun. Using a lumped parameter approach, a set of simultaneous differential equations was derived for the complex interaction of the propellant fluid, the driving injector and the projectile. The computer model was verified against a 20 mm experimental apparatus. Injector displacement, projectile displacement, and chamber pressure were compared for a nominal driving pressure of 140 psi. The important system parameters affecting projectile ram time and chamber pressure oscillations were investigated and potential problem areas for testing with actual propellant were identified.
