Abstract

Abstract: A given MMH/NTO rocket engine combustion stability with/without acoustic cavities was numerically simulated by pulse gun combustion instability model.Three MMH/NTO rocket engines combustion dynamic stabilities were compared and assessed. Numerical simulation and assessment results are agreeable with the engine hot test data.

Key words: Liquid propellant rocket engine;Combustion stability;Pulse gun model;Numerical simulation;Numerical analycis
