description The invention discloses a high-precision low-turbulivity flow supply system and a using method thereof.The high-precision low-turbulivity flow supply system comprises a high-pressure air source, a flow control valve, a first pressure stabilizing cabin, a honeycomb, a combined sonic nozzle, a sleeve, a ball valve, a second pressure stabilizing cabin and an air conveying pipe which are sequentially arranged, and the first pressure stabilizing cabin, the second pressure stabilizing cabin and an engine nacelle are each provided with a pressure sensor; and the first pressure stabilizing cabin is provided with a temperature sensor. By changing the number of the sonic nozzles and the upstream pressure of the nozzles, wide-range continuous adjustment of the flow is achieved, the structure is simple, and the flow adjustment precision is high; uniformity and stability of a flow field in the device are achieved in the mode of radial air inlet of the second pressure stabilizing cabin and rectification of the honeycomb de
