翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク High-Enthalpy Arc Heated Facility ： ウィキペディア英語版 High-Enthalpy Arc Heated Facility The High-Enthalpy Arc-Heated Facilities at Arnold Engineering Development Complex provide aerothermal ground test simulations of hypersonic flight over a wide range of velocities and pressure altitudes in support of materials and structures development. The facility is composed of three Arc Heaters: HEAT-H1, HEAT-H2, and Heat-H3 which can heat air up to 13,000 degrees Rankine through a controlled high voltage direct current electric arc discharge.〔(【引用サイトリンク】title=Factsheets : HIGH-ENTHALPY ARC-HEATED FACILITIES AT AEDC )〕 The test unit is owned by the United States Air Force and operated by Aerospace Testing Alliance. == HEAT-H1 == The HEAT-H1 Test Unit is an advanced performance arc-heated facility providing high-pressure, high-enthalpy test conditions for qualification of thermal protection materials, nosetips, and electromagnetic apertures and structures for hypersonic missiles, space access systems, and re-entry vehicles. The test unit utilizes a segmented arc heater with 200 electrically isolated segments which form the heater plenum. The unique segmented construction, with the anode and cathode at opposite ends of the plenum, allows the arc to be held at a fixed length to optimize heater efficiency, total enthalpy at high pressure, and flow uniformity. Normal operating conditions for the heater are about 20,000 volts and 1,200 amps, providing heater chamber pressures up to 120 ATM at high stagnation enthalpies. The H1 test cell is equipped with a multiple-strut, programmable rotary model injection system capable of positioning one to seven test models sequentially into the test free jet for preset dwell times. Transient calibration probes of various configurations are available to define heat flux and pressure conditions inside the test jet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「High-Enthalpy Arc Heated Facility」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
