Popis: Researches on shock-induced aerothermodynamics are conducted at Chofu Aerospace Center (CAC) of Japan Aerospace Exploration Agency (JAXA) for future planetary explorations currently entertained in JAXA. The hyper-velocity shock tube (HVST) simulates the thermochemical properties in the shock layer of hypersonic systems in flight, while the hyper-velocity expansion tube (HVET) reproduces those in the wake region of the test model. The hypersonic rarefied wind tunnel (HRWT) enables us to directly measure the rarefied aerodynamics of hypersonic systems in transition flows. The light-gas gun (LGG) allows us to clearly understand the wake flow structure of capsules in supersonic flight, from which the parachute ejection conditions are determined. Numerical investigations of shock-induced aerothermodynamics are overviewed as well.
