The low supersonic nozzles can produce steady low supersonic flow field with satisfied quality, double the allowable angles of attack and blockage limits and fill in the gaps in Mach number-attack angle range.

• 低超声速喷管可以在大堵塞的实验条件下,形成稳定的低超声速流场,消除风洞在大堵塞度实验时的马赫数空白区,从而使风洞的允许实验迎角和堵塞度范围增加一倍,并且能确保流场达到使用指标。
