Abstract: The design of wave-rider by osculatinsg method have been extended into outer cone with curve shock flow-field. Under different constraint conditions of shock wave shape (ICC curve)， four configurations of wave-rider have been designed by osculating convex/concave shock (OCS) flow-field method. The feasibility verification and effectiveness analysis of this method have been studied by numerical and theoretical ways. The results show that: (1)The contours of wave-rider configurations at compression surface and exit plane， and the shock wave shape (ICC curve) derived from MOC theory and numerical simulation are in good agreement with each other， with pressure deviation less than 5%. It indicates that the OCS method is applicable to the design of wave-rider. (2)While the ICC curve chooses hyper-ellipse equation whose ratio of short and long axis is 0.5， the pressure deviation of MOC theory and numerical simulation can be smaller than 1.6%. While the ratio of short and long axis is 2， the pressure deviation of MOC theory and numerical simulation can be smaller than 4.0%.

摘要： 将密切技术设计乘波体的应用推广至弯曲激波外锥流场中。针对不同激波形状(ICC)约束条件，在凸、凹激波曲外锥流场中，生成了四种构型的密切弯曲激波乘波体，采用数值模拟及理论分析的手段开展了密切弯曲激波乘波体技术应用的可行性验证及有效性分析。研究结果表明:(1)基于密切凸、凹激波外锥流场的乘波体乘波压缩面、出口截面压力分布、激波形状(ICC曲线)均与设计吻合，最大偏差小于5%，说明密切凸、凹激波外锥流场的方法设计乘波体是可适用的；(2)利用宽高比为0.5的超椭圆方程作为ICC控制曲线生成的乘波体，流场压力的理论解与数值解偏差可控制在1.6%以内，而宽高比为2的超椭圆方程作为ICC控制曲线生成的乘波体，流场压力偏差可控制在4%以内。
