Abstract: This study proposes a surrogate model that yields significant reduction in aerodynamic calculation for the initial sizing of the high-altitude long-endurance solar unmanned aerial vehicle (UAV) that uses solar and regenerative ...

Abstract: Estimating the wing weights of personal air vehicles (PAVs) is limited by lack of comparable data, as there were no PAV data available to the public. In this study, the limits were confirmed by verifying estimation equations ...
