Trisonic Wind Tunnel is a system to aid aerodynamic design of rockets and re-entry spacecrafts by characterising a scaled model by evaluating forces, moments, load distribution, unsteady pressures, acoustic levels etc.
Arguing that this is a major step towards India’s increasing self-reliance in the aerospace sector, Isro said: “The tunnel has an overall length of about 160m and has a maximum cross section of 5.4m. The tunnel can be used for testing various space vehicles in three flight regimes — below the speed of sound, at the speed of sound and above the speed of sound — hence the name trisonic wind tunnel.”
It added that the tunnel can simulate flight conditions from 0.2 times the speed of sound (68 m/s) to 4 times the speed of sound (1360 m/s).

“The huge structure was built with several hundred tonnes of steel and was implemented through Tata Projects India Ltd in association with Aiolos Engineering Corporation, Canada and fully realised by industries across India, including Walchandnagar Industries, Pune, Acoustic India, Tiruchirappalli, Artson Engineering, Nashik, Summits Hygronics, Coimbatore, Hydrocare Fluid Power Systems, Bengaluru and Siemens Energy, Ahmedabad,” Isro said.

Hypersonic vehicle
In a tweet unrelated to the wind tunnel, Isro said the space agency along with agencies from the three armed forces, jointly conducted Hypersonic vehicle trials.
“The trials achieved all required parameters and demonstrated Hypersonic vehicle capability,” Isro said, without divulging any more details about the project.
