An overview of micro air vehicle aerodynamics

Nomenclature AR = full-span aspect ratio, b/S b = wingspan CD = drag coefficient (three-dimensional) Cd = section drag coefficient Cf = skin friction coefficient CL = lift coefficient (three-dimensional) Q = section lift coefficient CL I CD = endurance parameter Ci/Cd = section lift-to-drag ratio c = root-chord length Rec = root-chord Reynolds number S = wing area t = wing thickness a = angle of attack
