The Mach number range of the transonic wind tunnel test is roughly 0.8~1.4, and the upper limit of the Mach number is mainly limited by the power. The power consumed by the transonic wind tunnel is enormous and increases rapidly with the increase of Mach number. When the Mach number reaches about 1.
A subsonic wind tunnel refers to a wind tunnel with an airflow Mach number ranging from about 0.4 to 0.8 in the test section, and the lower limit of the Mach number can also be as low as 0. The structure of the subsonic wind tunnel is similar to that of the recirculation low-speed wind tunnel, and t
A hypersonic wind tunnel means that the Mach number in the experimental section ranges from about 5 to 14, and the airflow temperature is high enough to prevent liquefaction in the experimental section when the airflow isentropically expanded to the above Mach number, but there is no wind high enoug
The icing wind tunnel is a large-scale special wind tunnel with complex performance. It is used to study the icing form, icing tolerance and other characteristics of the windward surface of different components and the external sensing part of the detection instrument when the aircraft is flying und

The air propeller is a tool that converts the power of the aero engine into the propulsion of the aircraft. The development of the propeller has experienced a process from rise to decline and rise again. Calculation of propeller performance and wind tunnel experiments are the basis for propeller des
A supersonic wind tunnel refers to a wind tunnel where the Mach number M of the airflow in the experimental section of the wind tunnel is between 1.4 and 5.
Compared with the horizontal wind tunnel, the vertical wind tunnel has the advantage that the gravity of the model is parallel to the axis of the test section, which can simplify the balance in the model rotation and the weight component of the rotating part, and is more suitable for the measurement
