A Fully-Coupled Underexpanded Afterburning Rocket Plume Program (The AIPP Code). Part 1. Analytical and Numerical Techniques.
Abstract
A comprehensive computer code has been developed to determine afterburning rocket plume characteristics over a wide altitude range. The code constitutes a significant advance over previous plume codes because it computes the plume shock structure while simultaneously accounting for turbulent mixing, nonequilibrium chemistry and gas/particle nonequilibrium effects. The capability of calculating properties in the subsonic region downstream of the Mach disc, downstream of the shock reflected from the triple point and in the far field has been incorporated into the code, but has not yet been debugged. This report describes the analytical and numerical techniques incorporated into the code, demonstrates that predictions of inviscid, chemically-frozen plume flows are as accurate as those obtained from a proven method of characteristics code and gives the results of some sample calculations for the SRAM missile.
