In our country the scramjet engine research has been carried out since the former National Aeronautical Laboratory in flight condition・・・<<read more>>
Report Number: R16E0074 Responsible Representative: Koichi Okita(Research and Development Directorate, Unit IV) Contact Information: Susumu Hasegawa(hasegawa.susumu@jaxa.jp) Members: Susumu Hasegawa Subject Category: Space(Space transportation) Abstract The aerodynamic characteristics of the airframe and the engine of the spaceplane which integrates the them will be clarified. Taking into consideration of the movement of the center of gravity, the aerodynamic center and the change of the engine thrust under the various flight conditions from take-off to high speed, aerodynamic characteristics of the spaceplane were・・・<<read more>>
Report Number: R16E0073 Responsible Representative: Koichi Okita(Research and Development Directorate, Unit IV) Contact Information: Susumu Hasegawa(hasegawa.susumu@jaxa.jp) Members: Takeshi Kanda Subject Category: Space(Rocket,Rocket engine,Space transportation) Abstract Integrated design technology of Spaceplane and its engine for future space transportation is studied, and conceptual design technology will be established. Wind tunnel tests, CFD simulation and conceptual study for estimation of transportation ability are conducted. The spaceplanes have larger thrust and larger engines than the planes have. Therefore, aerodynamic characteristics of the spaceplanes interacts・・・<<read more>>
