摘　　要：对燃气舵沿气流方向的横截面进行其外围的二维流场计算。计算中将燃气舵外围流场划分成三个区域,I区为钝头体头部绕流脱体激波后的亚跨声速区,Ⅱ区为脱体激波后的超声速区,Ⅲ区为膨胀波后的流动区。对各个流动区,分别用条带法、特征线法和普朗特尔-迈耶公式计算,获得各区的流动参数,为燃气舵的气动力、气动加热、烧蚀、传热、应力等计算提供流场数据。Two-dimensional flow field around the cross Section of gas rudder in gas flow direction is calculated. In calculation, the flow field is divided into three regions: subsonic-transonic region Ⅰ behind curved shock wave around blunt-nosed body, supersonic region Ⅱ behind curved shock wave and supersonic flow region Ⅲ behind expansion wane. The Strip-band method, characteristic method and Prandtl-Meyer formula are used, respectively, to calculate flow parameters in terms of the consideration of aerodynamics, thermodynamics, ablation, heat transfer and stress.
