A liquid propellant injector/combustor (LP I/C) fixture that produces pressure oscillations similar to those observed in liquid propellant gun firings has been designed, built and tested. The oscillations are due to combustion of the LP. Methods to reduce these oscillations are a high priority in the development of an LP gun for future Army artillery. Several different methods to reduce or eliminate the oscillations have been considered and tested. Experiments were conducted with three liners in the combustion chamber. Two showed little reduction in oscillations but the third, a flexible liner, eliminated the pressure oscillations. Results of these tests and other oscillation reduction methods will be presented.
