In this paper results of previous researches of two-mode full engine model for Mach number range from 3 to 6 are presented. The main aims of researches are to obtain characteristics of full engine model and its components (the inlet, the combustion chamber and the nozzle) in ramjet and scramjet regimes and to compare these characteristics with the calculation results according to CFD and to approximate (engineering) methods. Tests were carried out without ha supply (cold tests) and with fuel supply (study of ignition and combustion).Hydrocarbon and hydrogen fuel (gaseous or liquid) were used during the tests. 展开更多
