波阻 [bō zǔ]
[流] wave drag
- 本文给出硬质随行波减阻降噪贴敷层的几何参数设计及原理。
This paper states the geometric shape design and principle of rigid traveling wave pasted layer for reducing noise and drag. - 由于理论上可以将阻力降为零，行波壁减阻受到了广泛关注。
The traveling wavy wall has been regarded as a kind of advisable method because it can decline the resistance to zero theoretically. - 由于传统的工程计算方法只能估算旋成体从亚音速到低超音速的波阻增加量，不能计算阻力随马赫数增加而引起的变化。
As the tradition method can only estimate the addition of wave drag from subsonic to supersonic, and can not calculate the change of drag when Mach number increases.
