概要

論文の詳細を見る
A high enthalpy flow facility primarily for the high-temperature-resistant material research and for experimental studies on high temperature gas dynamics is built in ISAS, taking into account the demand for the application to the reentry vahicles. The facility is composed of Huels-type arc heater and necessary subsystems for power supply, water cooling, evacuation and operation/control. After briefly describing the facility, characterized facility performance and flow conditions for the heating test purposes are presented. It demonstrates the planned simulation capability, in terms of heating and impact pressure, which ranges 0.1 to 5 MW/m^2 of heat flux and 10 to 100 kPa of impact pressure by two operation configuration of vacuum and open-to-air condition. Equipped measurement instruments for various needs both for material testing and studies of aerothermodynamics including state-of-the-art optical and laser diagnostics are also outlined.
