Determination of Mission Failure for Propeller-Driven High-Altitude, Long-Endurance UAVs Under Icing Conditions

What is it about?

Propeller icing is a significant issue for high-altitude, long-endurance (HALE) unmanned aerial vehicles (UAVs). These UAVs are designed to operate in the upper atmosphere with long wings and lightweight structures, but these features make them vulnerable to icing, especially during the climb phase. While most research has focused on icing's effects on the fuselage and wings, this study highlights how icing impacts the propellers. By using 3D simulations and real data, the study shows that propeller icing can reduce battery life and motor efficiency, which could hinder mission success. This research suggests that propeller icing should be carefully considered when designing UAVs or planning missions.
