NONSTATIONARY FLOW IN THE MODEL CHANNEL OF A RAMJET ENGINE IN PULSE-PERIODIC ENERGY SUPPLY
V. P. Zamuraeva} and A. P. Kalininab} UDC 533.6.011 A study has been made of the influence of the pulse-periodic supply of energy that is equal to the energy released in the combustion of hydrogen in air on the structure of supersonic flow in a channel of variable cross section, modeling the duct of a ramjet engine. The flow has been modeled on the basis of two-dimensional nonstationary gas-dynamic equations. Different flow regimes have been obtained depending on the configuration of the zones of energy supply and the excess-air coefficients. a}Institute of Theoretical and Applied Mechanics, Siberian Branch of the Russian Academy of Sciences, 4/1 Ul.
