It is necessary to simulate the high enthalpy, high pressure, Machnumber and the same concentration of oxygen species as air in hypersonic flight.
地面实验设备必须要模拟高超音速飞行状态下气流的焓、压力、M数和空气中氧气的组分。

The aviation bomb is flying in the high density atmosphere layer. Its fight Machnumber is generally 0.9.
航弹主要是在稠密的大气层中飞行，巡航马赫数一般在0.9附近。

The results show that the transition more likely happen under the situations with high azimuthal wave number and speed, and at a relatively low machnumber and high Reynolds number.
