Hypersonic Wind Tunnel

About Hypersonic Wind Tunnel

Marketing Overview

Our hypersonic wind tunnel systems are designed for cutting-edge aerodynamic research in extreme high-speed regimes (Mach 5 and above). Engineered to simulate realistic flight conditions for missiles, spacecraft, and re-entry vehicles, these tunnels enable precise analysis of high-temperature flow physics, shock interactions, and aerodynamic heating.

Utilizing advanced blowdown and vacuum-assisted flow generation, combined with high-temperature air heating systems, the tunnel delivers stable hypersonic flow conditions. Multiple configurationsincluding shock tunnels and hot-shot facilitiesallow flexibility for a wide range of experimental requirements, from force measurement to heat transfer and ablation studies.
