Abstract

Solid propellant ramjet with dual underside inlet was selected for study. By using orthogonal design, a three-dimensional flow field model of afterburning chamber was build to study the effect trends of three structural parameters on the mixing and combustion efficiency. The feasibility of numerical simulation was also verified by ground tests. The results got from range analysis indicate the effect trends and optimal levels of each structural parameter, while the variance analysis indicates the influence significance of various structural parameters on combustion efficiency. As a result, the length of the afterburning chamber is highly significant.

Key words： solid rocket ramjet; orthogonal design; structural parameters; combustion efficiency
