Aircraft gust alleviation technology

[Added on] [Last modified on]

Report Number: R16E0031 Responsible Representative: Kazutoshi Ishikawa(Aeronautical Technology Directorate, Next Generation Aeronautical Innovation Hub Center) Contact Information: Kenichi Saitoh(ksaitoh@chofu.jaxa.jp) Members: Kenichi Saitoh, Hamidreza Kheirandish Subject Category: Aviation(Aircraft) Abstract In the research and development of aircraft gust alleviation technology, we aim to reduce the accident in the cabin hit by clear air turbulence. To suppress such an aircraft motion, we are developing a control technology using LIDAR which detects the turbulence. Currently, we are verifying the theory by the wind tunnel・・・<<read more>>
