Process of shut-down and restart of solid propellant ramjet has been investigated. The
article presents the results of mathematical modeling shut-down of ramjet gas generating
system by changing the critical section of the gas generator and the creation of unsuita-
ble burning conditions in the afterburner chamber. The ways of refining the model by
examining the boundaries of sustainable fuel combustion at different combinations of
pressure, temperature and coefficient of excess oxidant as well as the boundaries of
steady operation of the air-intake device in the presence of a gas generator jet are out-
lined.
Keywords: ramjet, gas generating system, solid propellant, ramjet shut-down, ramjet
restart.
