乘波体在飞行中马赫数变化会对乘波体产生很大影响,不同马赫数对应不同乘波体外形,获得稳定飞行马赫数范围,对于乘波体气动特性研究将具有重要的指导意义。利用数值模拟方法对无粘锥体流场乘波体进行设计并分析其基本气动特性,得出基于Ma=6,α=0°流场乘波体在满足稳定性飞行的马赫数范围。并在此范围内对乘波体进行分段数值模拟得到升力系数、阻力系数及升阻比变化特性。研究结果为提高乘波体升阻比和控制飞行速度提供了理论基础。

Mach number change in flight of wave-rider has great influence on the wave-rider, different Mach number corresponds to different wave-rider shape, and the range of Mach number is stable.In this paper, a numerical simulation method was used to design and analyze basic aerodynamic characteristics based on non stick cone-flow field, and the Mach number range of the wave-rider satisfied stability of Ma = 6, a = 0°.In this range, lift coefficient, drag coefficient, lift-drag ratio and other related parameters were obtained.The results provide a theoretical basis for improving lift-drag ratio and controlling flight velocity of the multiply.
