Research works of ethanol propulsion system for the future rocket-plane experimental vehicle

Experimental research works for the ethanol propulsion system has been performed in JAXA/Space Transportation Mission Directorate (STMD) as a part of study for future reusable launch vehicle.. Under this program, 1000 kgf-class (2200 lbf) rocket engine testing, material-matching and critical heat flux (CHF) studies and other related works were conducted in 2009 to 2010. This paper provides an overview of this engine experimental program and the results.
