Symmetrical aerofoils and the influences of damage or debris for Unmanned Aerial Vehicles

Abstract

Unmanned Aerial Vehicles are typically low-cost and frequently have aerofoils sections that are symmetrical as these are more economical to manufacture. Low speeds are possible and stability acceptable and lift can still be generated providing the angle of incident is greater than zero. The research presented here is with a focus on how susceptible if the leading edge is damaged or has debris resulting from operating on grass or on airfields in non-standard conditions.
