摘　　要：乘波体飞行器是近年兴起的新概念飞行器。现提出了一种组合前缘的乘波体设计方法以改善飞行器前体的预压缩性能,并用Navier-Stokes方程进行了数值模拟,就密度流、压力系数、马赫数、总压等参数与普通乘波体进行了对比,结果表明,该设计方法能显著改善飞行器前体的预压缩性能。Waverider vehicle is a newly concentrated conception. Here we present a composite waverider design method to improve the pre-compression quality of vihecle forebody. Computation is done and numerical resuhs are compared between the normal waverider and the composite waverider, A new comparing method of flowfeild parameters is presented, which concerning probability and statistics. The compared parameters include density flow, pressure, maeh number and total pressure. Conclusion is that the pre-compression quality is improved.
