Analysis of aerodynamic characteristics for a flying-wing UAV with asymmetric wing damage

This paper investigates the influence of aerodynamic characteristics for a flying-wing Unmanned Air Vehicle (UAV) subject to asymmetric wing damage. Firstly, the conceptual design of a flying-wing UAV is introduced. The UAV model with right wing damage is constructed, from which the vehicle's physical characteristics, such as mass, center of gravity (C.G.) and moment of inertia are calculated. Next, the aerodynamic model of damaged UAV is established in DATCOM, and the aerodynamic coefficients of UAV under different damage conditions are computed. Based on the obtained aerodynamic coefficients, the effect of asymmetric wing damage for the UAV is analyzed. Furthermore, the influence of the static stability is analyzed according to the aerodynamic derivatives.
