As this mid-term target, it is proposed that a subscale prototype engine will be produced and demonstrated under sea-level-static and supersonic conditions (Mach 6) for getting fundamental key technologies and valuable experiences. Engine system optimization analyses for an actual TSTO space plane by the precise components data on the performance and weight as well as the dynamic characteristics along the accelerating trajectory is also investigated. In this year, fundamental key results were obtained by a trade-off study to decide the prototype engine cycle, a study of the defrosting system on the precooler (a cryogenic heat exchanger), wind tunnel tests of air inlets and nozzles and an application study of the composite materials., 資料番号: AA0047944005, レポート番号: JAXA-RM-04-009}, title = {極超音速ターボジェットエンジンの研究開発}, year = {2004} }
