The goal of the work: development of methodical and experimental theoretical basis to provide research of parameters of controlled gas flows with high density of energy. Research methods: mathematical modelling, experimental data processing, informative and design search. Results: theory is developed and new data of controlling thermogasdynamic processes parameters in supersonic section of the liquid propellant nozzle chamber are obtained. Features of pressure disturbances and force diagrams on nozzle surface at the interaction between flow and jets of fuel components are obtained. Theoretical basis for calculation of jet barriers (interceptor) parameters on nozzle surface during injection through interceptor jets of fuel components are obtained. Features of interaction of bilaminar supersonic flow and mentioned hard-stream interceptor are determinated. Theoretical basis, methodical support and software for research of thermogasdynamic processes parameters with superhigh (detonation) speed of energy release in impulsive rocket engine chambers are developed. Results of preliminary calculations and experimental research of mathematical and physical impulsive detonation rocket engine models are given. Results of research will be used for further development scientific basis for the improvement of rocket engines. Product Description popup.authors popup.nrat_date 2020-04-02 Close
