Numerical investigation of lateral jet interaction effects on the hypersonic quasi-waverider vehicle

Abstract

Numerical simulations are carried out to investigate lateral jet interaction effects for the hypersonic quasi-waverider vehicle. A reasonable jet nozzles layout is proposed. Based on three-dimensional viscous compressible Reynolds Averaged Navier-Stokes codes, comparisons of the jet interaction flow structures between quasi-waverider vehicle and general axisymmetric vehicle are conducted. Furthermore, the effects of lateral jet control are examined for different angles of attack and free-stream Mach numbers. From detailed flow structure and pressure distribution analysis, the quasi-waverider vehicle gets a better effect of lateral jet without “wrap-around” the body. With the increase in angle of attack or free-stream Mach number, the attitude control moment reduces and the effect of lateral jet decreases.
