The development of high enthalpy wind tunnel and its test technology are the cornerstone to help mankind enter the hypersonic era
and the great progress has been achieved in recent years. High enthalpy wind tunnels with four typical driving modes are introduced. Those are the air-directly-heated hypersonic wind tunnel
the light-gas-heated shock tunnel
the free-piston-driven shock tunnel
and the detonation-driven shock tunnel. Theories and critical techniques for developing these wind tunnels are introduced
and their merits and weakness are discussed based on tunnel performance evaluation. The measurement techniques are usually included into wind tunnel techniques because that the hypersonic and high-enthalpy flow is a chemically-reacting gas motion and its diagnose needs specially-designed instruments. Three measuring techniques are introduced here
including aerodynamic heat flux sensors
aerodynamic balances
and optical diagnose techniques. These techniques were usually developed for conventional hypersonic wind tunnels and combustion research
and are further improved to measure the hypersonic and high-enthalpy flows. The prospect for developing the experimental techniques of hypersonic and high-enthalpy wind tunnels is presented from author's point view.
