Abstract

We proposed a new type arc cutting process with the DC (Direct Current)-pulsed power supply using a GHTA (Gas Hollow Tungsten Arc) for space application. The arc cutting mechanism was clarified by the observation of the cutting situation in vacuum. The effect of the cutting parameters on the cutting form was investigated by the pure aluminum cutting experiments. The optimum cutting parameters for 2 mm plate thickness aluminum cutting were decided from the experimental results., 資料番号: AA0063706019

Abstract

The coking phenomenon within low- density ablative material exposed to aerodynamic heating is studied. The char density of the tested material is measured by slicing the material thinly, and by weighing each of the sliced test pieces. Measured density profiles of the tested materials are compared with the calculated results obtained by a thermal response code. The surface and internal state of both pre- and post- materials are observed by using Scanning Electron Microscope (SEM) and X-ray Computed Tomography (CT). The results show that the measured density profiles is inversely increased to the heated surface. The density increase is likely due to the deposition of a solid carbon in the char region during aerodynamic heating., 資料番号: AA0063742010, レポート番号: JAXA-SP-07-016

Abstract

再使用型宇宙輸送システムにおける大気圏突入時に必要な機体の熱防護系の試験、特に触媒性の評価には、気流に汚れの無い加熱風洞が必要とされる。このため、2001年度から「誘導プラズマ加熱風洞」の整備に着手した。本報告ではその風洞の概要や整備の計画などについて述べる。, 資料番号: AA0047430004, レポート番号: JAXA-SP-03-005
