To compensate for increasing fan diameter, we are developing lightweight fan blades that have higher aerodynamic efficiency by・・・<<read more>>
Report Number: R16E0022 Responsible Representative: Hisao Futamura(Aeronautical Technology Directorate, Propulsion Research Unit) Contact Information: Hideyuki Taguchi(taguchi.hideyuki@jaxa.jp) Members: Motoyuki Hongoh, Masaharu Hiruma, Jun Butsuen Subject Category: Aviation(Aircraft engine) Abstract Research and development to establish technologies for a Mach 5 class hypersonic passenger aircraft that can cross the Pacific Ocean in 2 hours is being conducted. Hypersonic passenger aircraft flying at Mach 5 will be exposed to higher temperature environments than supersonic aircraft flying at around Mach 2. Therefore, research and development・・・<<read more>>
Report Number: R16E0021 Responsible Representative: Hisao Futamura(Aeronautical Technology Directorate, Propulsion Research Unit) Contact Information: Mitsumasa Makida(makida@chofu.jaxa.jp) Members: Mitsumasa Makida, Naoki Nakamura Subject Category: Basic Research(Design technique) Abstract For the development of combustors with practically complicated configuration which consist of many parts, it is important to develop CFD technologies to conduct many parametric studies effectively by changing parameters for configurations. In this research, we utilize a multi-block structured grid solver, which conduct large scale cold-flow simulation inside combustors with real complicated・・・<<read more>>
