Abstract

In order to analyze the influence of different factors such as sub/supersonic inlet air flow ratio, air-fuel ratio, secondary fuel injection and the straight length on combustion efficiency, a numerical simulation study of supersonic combustion of solid fuel in dual combustor was conducted and then the experiment was carried out. The results show that an optimal flow matching exists in the design of supersonic inlet and combustor; it can evidently improve combustion efficiency by reducing air-fuel ratio, using of the secondary fuel injection and increasing the straight length, and can improve the combustion efficiency; Solid fuel can be successfully ignited, and the supersonic combustion is established in the supersonic combustor.

Key words： solid propellant fuel; dual combustor ramjet; supersonic combustion; numerical simulation
