Pressure Oscillations in a Regenerative Liquid Propellant Gun and Influence of Random Processes
Abstract
A one-dimensional model of the regenerative liquid propellant gun (RLPG) interior ballistic cycle has been developed in which the jet breakup and energy release is governed by a Taylor formulation. The model allows a random component in the jet breakup to simulate conditions which may exist in the gun. The random component produces rough combustion with energy being released in a nonuniform manner. The resulting chamber pressure history exhibits oscillations qualitatively similar to those observed experimentally. Moreover, it is shown that even though the energy release is confined to the chamber, the oscillations can be propagated downbore to the base of the projectile, thereby presenting a potential hazard for sensitive munitions. A possible remedy is discussed.... Liquid propellants, Combustion instability, Oscillation, Regenerative, Pressure oscillations.
