Abstract: In order to study the effect of lateral jets on direct force control performance of hypersonic interceptor missile, computational technique of Reynolds-averaged Navier-Stokes equations discretized under cell-centered finite volume framewoks, using an implicit scheme which is the lower-upper symmetric successie over-relaxation (LU-SSOR) scheme in time discretion and upwind schemes in spatial discretions a detailed numerical investigation of the interaction between jets and the external flow was processed for the endo-aerosphere interceptor missile with multiple-jet. And detailed flow visualization studies highlight of the complex nature of the three dimensional interaction phenomena were obtained and provided insight into the physics of the flow structure. The results show that the interaction phenomena of multiple lateral jets induced the flowfield are significant different from that of a jet alone, and the pressure field before the ahead jet is not affected by after jet and the interaction efficiency of the after jet in the wake of ahead jet will be affected by the ahead jet.
