摘要：
A series of experimental studies of pulse-periodic gas-dynamic combustion control was carried out in order to increase the efficiency of the workflow in combustion chambers of variable geometry. Controlled quasi-stationary kerosene combustion mode in a high-enthalpy flow is implemented. In the experiments, the geometry of the tract, the intensity of the control pulses, and the flow rates of the fuels in the constant section channel and in the expanding part were varied. Parameters of control pulses are found and the requirements for the length of the constant section are formulated. Based on the data obtained, an engineering method has been developed for applying pulse-periodic gas dynamic control of the workflow efficiency for high-speed combustion chambers.
