Modeling of the Process of Motion of a Scramjet in the Atmosphere
- 54 Downloads
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. Investigations are performed for regions of the incoming supersonic flow, inside of the scramjet channel, and outside of it. Dependences of the total aerodynamic force projection onto the direction of scramjet motion on its speed and mass fuel supply rate are analyzed.
