The wind tunnels steady wind velocity control systems are composed of wind tunnel rev control system and wind tunnelvelocity and pressure control system.
风洞稳风速控制系统主要由风洞稳转速控制系统和风洞稳速压控制系统构成。

The tests were carried out in a constant volume tunnel in which the flow velocity, the environmental density and its temperature can be changed.
试验在专门研制的可变流场速度、可变环境密度和可变环境温度的定容风洞中进行。
