In China, a hypersonic wind tunnel with a speed of up to Mach 30 will be completed in 2022

According to the statements of the Central Television of the Celestial Empire, the construction of a hypersonic wind tunnel will be completed next year.

After commissioning, the JF22 wind tunnel will be able to create a flow rate of 10 km per second, which is 30 times higher than the speed of sound, and also simulate an altitude of 40 to 100 km.

New wind tunnel and its unique capabilities

As you know, wind tunnels are designed to test the behavior of various configurations of aircraft or individual elements at the stage of their development.

So, thanks to such pipes, engineers evaluate aerodynamic noise, drag, flow around, adhesion of air flow, as well as the formation of turbulent flows.

Most of the existing wind tunnels in the world are capable of testing elements at flow rates up to Mach 3. Some installations are capable of short-term hypersonic current velocity.

So the Chinese version JF12 capable of providing a flow of Mach 9, but within only 100 milliseconds.

To development JF22

(245-meter wind tunnel) engineers of the Celestial Empire started back in 2018, and in the first stages it was assumed that that the pipe will provide a flow rate of Mach 25 due to the use of detonation chambers (though only briefly).

This speed will be provided through the use of detonation chambers, in which a mixture of oxygen, hydrogen and nitrogen will be ignited and then exploded.

So according to a statement by China Central Television (which was published on August 22), the construction of the wind tunnel should be completed by the end of 2022. And upon completion of all commissioning works, it will be able to provide a flow rate of Mach 30.

More detailed technical parameters of the installation were not disclosed. But the installation being created will allow Chinese engineers to closely study the behavior of various parts and installations at hypersonic speed.

Well, we can only be glad for our Chinese colleagues and wish them fruitful work and new discoveries.
