The operation modes of the engine included an ejector-jet mode, a ramjet mode, a scramjet mode and a rocket mode. Characteristics of the engine operating conditions were studied analytically. Study of the effective impulse function revealed that a higher specific impulse was preferable in supersonic flight, whereas a greater thrust coefficient was preferable in hypersonic flight. These characteristics were examined by simulating an engine operating in an aerospace plane flight. A comparison was made between several engines with different combinations of thrust and specific impulse when used for the transportation of a mass into orbit. The mass that could be carried into orbit was larger with a ramjet mode of higher specific impulse and with a scramjet mode of greater thrust. In the present study, the thrust augmentation effect of the ejector-jet mode was also found to be small at low subsonic speeds and to increase with increasing flight Mach number.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
