LNG rocket engines have been investigated among many countries because LNG has better characteristics as a fuel of rocket engine, i.e. longer storage, lower cost and non-toxic. In Japan, we are conducting research and development on a regenerative cooling LOX/methane engine to achieve higher performance. In order to realize higher performance, LOX and methane have to be mixed and burned with higher efficiency and more stable. Therefore we prepared many single shear coaxial elements which varied design parameters and we performed firing test for the purpose of surveying combustion characteristics of LOX/methane under high pressure condition. The result for all pre-burner elements shows that combustion is stable and generated soot quantity is small., 形態: カラー図版あり, 形態: CD-ROM1枚, Physical characteristics: Original contains color illustrations, Note: One CD-ROM, 資料番号: AC1600100000}, publisher = {日本航空宇宙学会北部支部, Northern Branch of the Japan Society for Aeronautical and Space Sciences}, title = {高圧燃焼下におけるLOX/LNG(メタン)同軸型噴射器の燃焼特性について}, volume = {17}, year = {2016} }
