Abstract

When an unmanned aerial vehicle(UAV) encounters cloud layers with high humidity and sub-freezing temperatures, such as ice particles or supercooled water droplets, the UAV's surface can undergo icing. Icing accretion on an aircraft can lead to various issues, including reduced stall angle and decreased controllability, which can potentially result in a direct threat to safe flight. In this study, a comparative analysis was conducted on the ice accretion occurring on UAV under the non-SLD condition, which is the continuous maximum(CM) condition of FAR Appendix C, and the freezing rain SLD condition of Appendix O by computational simulation. More ice is accreted in the SLD condition than in the non-SLD condition, but aerodynamic performance is reduced less than non-SLD condition. This is because the ice shape of SLD conditions is created streamlined along the UAV surface. In the future, this study can be extended to the design of ice protection systems and utilized in icing certification for UAVs in SLD conditions.
