Two-staged vehicle to low earth orbit is thefinal target of the current study, with hydrocarbon fuel (namely ethanol) in scope for easy and low-cost operation, andfiner system packaging due to high density. To compensate the Isp loss associated with usage of hydrocarbon fuel,airbreathing technology is fitted to the booster stage of the vehicle, i.e., application of a RBCC (Rocket Based CombinedCycle) engine. This engine is to embed rocket engines within a ramjet-duct, with various operation modes according toflight speed. Research activity has been conducted at JAXA to establish design methodology of this engine system withan emphasis on aerodynamic design with hydrogen as its fuel. Status of the research activity is herein reported., 資料番号: AC1400023000, レポート番号: JSASS-2013-4276}, publisher = {日本航空宇宙学会(JSASS), The Japan Society for Aeronautical and Space Sciences(JSASS)}, title = {ロケット複合エンジンシステムにかかる技術研究状況について}, year = {2013} }
