The testing tube is roughly twice as large as comparable facilities in the West, with a diameter of 80cm (2.6 ft).
The most giant free-piston-powered shock tunnel in the world is already operational in southwest China. It enables low-cost, excellent wind tunnel tests for hypersonic research.
The facility can simulate severe flight conditions at speeds ranging from 2.5 to 11.5 kilometers per second (1.55−7.14 miles per second), or more than 33 times the speed of sound, according to a report published by South China Morning Post (SCMP) on Thursday.
