• 一般注記: A large launch vehicle, H-II, has been developed in Japan. The launch vehicle will use a large LOX/LH2 engine, LE-7, which also is under development. The cryogenic propellant feed pumps of the LE-7 are characterized by large flow rate and high delivery pressure. Definition of efficiency and head of the LE-7 cryogenic pumps were required because cryogenic fluids show relatively large compressibility. The polytropic efficiency, which is used in compressors, sometimes is referred to as the true efficiency since it eliminates the effect of compressibility. An efficiency and head similar to the polytropic efficiency and head were newly defined and compared with the adiabatic efficiency and head, and it was concluded that the defined efficiency and head were fairly close to the efficiency and head of the LE-7 cryogenic pumps.; 資料番号: NALTR1031000; レポート番号: NAL TR-1031
