The current target of the present study is to build a quick-response and maneuverable main engine of a sounding-rocket like flying test bed which will be applied to the hypersonic air-breathing propulsion researches in the near future. The application to the spacecraft propulsion is also considered due to its compatibility in low-temperature operation environment. Two series of static firing tests were performed with 700 N class gas generator models so far. Current test results showed that valuable design data were collected and operational procedure was verified. Potential of application of composite materials to the combustion chamber was also examined from the chamber wall heat flux data obtained and the result of firing test using a thick SFRP (Silica Fiber Reinforced Plastic) chamber., 資料番号: AA0063882000, レポート番号: JAXA-RR-07-027}, title = {亜酸化窒素(N2O)/エタノール推進系の実験研究}, year = {2008} }
