Abstract

In this paper two new afterburning chamber mixing structures of swirl solid rocket ramjet were designed, and the numerical simulation of the mixed combustion flow field of afterburning chamber under the action of the mixed structure was carried out. The effects of swirl mixing structures on mixed combustion in the afterburning chamber were analyzed and compared the calculation results with two reference afterburning chamber mixing structures. The results showed that swirl mixing structure could strengthen the the effect of the mixed combustion in the combustion chamber, and greatly enhance the characteristic velocity of solid rocket ramjet afterburning chamber. The total pressure recovery coefficient of the combustion chamber meets the design requirements, but the swirling flow in the afterburning chamber would weaken the function of ramjet nozzle force to a certain extent.

Key words： solid rocket ramjet; afterburning chamber; cyclone; mixing and combustion; characteristic velocity
