"The tunnel has a total length of approximately 160 meters and has a maximum cross-section of 5.4 meters. It is designed for testing scaled models of rockets and spacecraft in the subsonic, transonic and supersonic ranges (Mach 4). This important feature will aid in the aerodynamic design of future space vehicles," Purohit said.
What are wind tunnels?
“The Trisonic Wind Tunnel is a special facility that helps in designing rockets and spacecraft by testing “scaled models” under simulated flight conditions. It helps in testing various aspects such as forces acting on the model, "How to balance [moments], evaluate pressure distribution, unsteady pressure, and even acoustic levels. This information is important for designing aerodynamically efficient rockets and spacecraft," Purohit underlined.
