Abstract

In order to enhance the combustion performance of solid rocket-ramjet, numerical simulation (CFD) and connected-pipe experiment were carried out to study the effect of mixing device on the combustion performance in afterburner. The results show that the mixing-enhanced device can effectively improve the combustion performance in afterburner. Under the typical condition, the total pressure and characteristic velocity in afterburner would be raised by 8% by using the mixing device and the nominal thrust of the motor would be raised by 19%.

Key words： solid rocket-ramjet motor; mixing-enhanced device; numerical simulation; connected-pipe test
