From the flight condition to the ground, it must obey the principles for the shorting and scaling model.

从飞行条件转换到地面模拟条件，需考虑截断发动机的原则以及发动机的缩尺效应。

By using CFD technology, the inlet fluid fields at different typical flight condition along the flight trajectory are numerically simulated.

利用CFD数值模拟手段，根据选定的飞行轨迹和进气系统调节规律，对沿飞行轨迹各典型状态的流场进行了计算。

Gain matrix K is a constant matrix design at sea-level static condition, and should be transformed to actual flight condition with similarity correction factors.

增益矩阵在标准大气条件下设计，并通过相似理论将其扩展到全线。

It may seem obvious that a long-haul flight has caused the condition to develop in a passenger on such a flight, but there are other factors that can have an adverse effect on the circulation.

Fortunately, during our flight, that condition stabilized, and we ended up with a situation where all the winds were going in the same direction, all heading east.

ENGADGET: Art Thompson, Red Bull Stratos' technical project director, talks circuit breakers, wind shear and biomedical data

For those who have not, it is a condition of flight in which lift is reduced to such an extent that normal flight ceases and the aircraft becomes a brick.
