Description
Summary:The paper presents the results of an experimental and numerical study of the operating process of a valveless airbreathing pulsating jet engine. The possibility of boosting the engine by changing the internal aerodynamics and accelerating the combustion process is discussed. The results are compared to the Rayleigh stability theory and an assumption is made about the feasibility of matching the combustion rate with the gas exchange wave process.
