Report Number: R16E0070 Responsible Representative: Yuichi Matsuo(Aeronautical Technology Directorate, Numerical Simulation Research Unit) Contact Information: Yuya Ohmichi(ohmichi.yuya@jaxa.jp) Members: Yuya Ohmichi, Gunpei Morikami, Yuji Koike, Kota Dohi Subject Category: Basic Research(Numerical analysis,Modeling) Abstract Recently, data analysis methods for massive data sets are important because the massive data can be relatively easily obtained thanks to the development of the computers and numerical simulation techniques. In this study, we are developing such data analysis tools which extract patterns from a massive data obtained・・・<<read more>>
Report Number: R16E0069 Responsible Representative: Yoshikazu Makino(Next Generation Aeronautical Innovation Hub Center, Aeronautical Technology Directorate) Contact Information: Yasutada Tanabe(tan@chofu.jaxa.jp) Members: Takashi Aoyama, Yasutada Tanabe, Masahiko Sugiura, Hideaki Sugawara, Kuniyuki Takekawa, Hisato Takeda, Takahiro Yamamoto, Shogo Goto Subject Category: Aviation(Flight operation) Abstract High fidelity CFD simulations for three types of multi-rotor drones used for agricultural spraying are performed. The sprayed particles are also dynamically simulated considering their gravity and air resistance. The rotating propellers and the major body and support arms・・・<<read more>>
Report Number: R16E0068 Responsible Representative: Takahiro Yamada(Institute of Space and Astronautical Science, Division of Spacecraft Engineering) Contact Information: Hirobumi Saito(saito.hirobumi@jaxa.jp) Members: Tomoya Fukami, Vinay Ravindra, Hirobumi Saito, Kengo Ando, Pyne Budhaditya, Prilando Rizki Akbar Subject Category: Space(Space utilization) Abstract We are goint to develop synthetic aperture radar system that can be onboard on a 100kg class satellite and to verify it on ground. Conventionally radar observations have required large or medium satellite with 500-1000kg mass. Our research and development may・・・<<read more>>
Report Number: R16E0067 Responsible Representative: Noriaki Ishioka(Department of Interdisciplinary Space Science) Contact Information: Ryoji Takaki(ryo@isas.jaxa.jp) Members: Ryoji Takaki, Taku Nonomura, Seiji Tsutsumi, Yuma Fukushima, Soshi Kawai, Yuki Kawaguchi, Ikuo Miyoshi Subject Category: Basic Research(Design technique,other ) Abstract We develop a high-speed/high-precision computational program using a quasi-first principle method, which can faithfully reproduce the actual flight environment to understand the true nature of fluid phenomena. Specifically, we develop a high-precision compressible flow solver with geometric wall models and LES (Large Eddy・・・<<read more>>
