subsonic flight meaning in English
亚音速飞行
Examples
- The method of wing shape optimization of space shutlle has been developed with penalty function approach in which the objective function is the mass of the wing and the constraints are the hypersonic re - entry flight cross range , lift / drag ratio , and subsonic flight lift / drag ratio , the margin of the longitudial static stability and the magnitude of the horizontal landing speed etc
摘要介绍了在满足高超音速再入横向机动航程，高超音速再入飞行时的升阻比，亚音速进场飞行时的升阻比，纵向静稳定性裕度和水平着陆速度等飞行性能设计要求下，用罚函数法寻求使航天飞机机翼质量为最小的外形优化方法并给出了算例。
