Modelling of internal ballistics processes in scramjet engine during the motion in the atmosphere

Abstract

Physical and mathematical model and results of modeling of the processes proceeding in the channel of a scramjet and in the surrounding atmosphere are presented for Mach numbers of 6.7–10. The mathematical model is based on the gas dynamics equations written in the two-dimensional approximation taking into account combustion of a gaseous fuel. Dependences of the total aerodynamic force projection onto the direction of scramjet motion on its speed and mass fuel supply rate are analyzed.
