JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18ETET26 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Masashi Kanamori(kanamori.masashi@jaxa.jp) Members: Masashi Kanamori, Takahiro Yoshikawa Abstract It is of a great importance to predict a so-called low-speed buffet phenomenon for realizing safer flight. During a flight with a high angle-of-attack condition in a low-speed regime, separated flow at a leading edge of main wing impinges on its tail,・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18ETET27 Subject Category: Skills Acquisition System PDF Responsible Representative: Yoshikazu Makino, Aviation Systems Research Unit, Aeronautical Technology Directorate Contact Information: Ryotaro Sakai(sakai.ryotaro@jaxa.jp) Members: Christian Nauck Abstract Innovative drag reduction technologies are investigated to reduce the fuel consumption for a conventional aircraft configuration. Aircraft noise prediction technologies and the conceptual design technologies are also developed for future aircraft which achieve low noise and high efficiency. In this research, aeroacoustic simulations have・・・<<read more>>
JAXA Supercomputer System Annual Report April 2018-March 2019 Report Number: R18ETET23 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Rui Toyonaga(toyonaga.l.0121@ruri.waseda.jp) Members: Rui Toyonaga Abstract For the development of a aircraft engine combustor with high environmental compatibility, we develop the combustion calculation method that can reproduce the pressure propagation and chemical reaction with practical calculation cost. In addition, a verification calculation of this calculation method is conducted on the・・・<<read more>>
