| Outline of Final Research Achievements |
Cranked-arrow main wings are quite suitable for supersonic airplane attaining both subsonic and supersonic flight capability. This study aims to characterize aerodynamic derivatives caused by pitching, rolling, and yawing rates of such a configuration with a cranked-arrow main wing. Dynamic wind-tunnel tests and CFD calculations were carried out using an airplane model actuated at various attitude rates. Data were acquired with careful noise/interference reduction and hysteresis analysis was carried out intensively. The results clarified extensive characteristics of the static and dynamic derivatives. This achievement will contribute to establishment of autonomous gauidance/control systems as well as to comprehensive understanding of aerodynamics and flights of high-speed aircraft.
