Abstract: Based on Solar-power Unmanned Aerial Vehicle (UAV) of high altitude, exploring aerodynamic performance analysis is carried out for bionic full-wing typical solar-power UAV. Firstly, typical low Reynolds wing is verification calculated by laminar kinetic energy model method, based on the finite volume method. Secondly, design features of bionic full-wing typical solar-power UAV are reviewed. Thirdly, the basic aerodynamic performance of UAV is simulated by laminar kinetic energy model method. Finally, directional-lateral performance and rudder efficiency of UAV are calculated and analyzed to gain more comprehensive aerodynamic performance. The research shows that: bionic full-wing typical solar-power UAV is promising configuration type，whose flow interference is small, and has three-dimensional low Reynolds flow features of typical full-wing, high basic aerodynamic performance (cruise lift-drag-ratio is greater than 34, the longitudinal static stability is about 8%), static stabile directional-lateral performance and great rudder efficiency.
