High Enthalpy Shock Tunnel (HIEST)
World’s largest shock tunnel
This is the world’s largest shock tunnel.
It is possible to conduct a test in a simulated re-entry environment using a 50 cm size model.
Moreover, using a model that measures up to around 2 m, it is possible to conduct tests on combined cycle engines and SCRAM jet engines that are fueled by hydrogen gas.
