Abstract
To obtain an optimal aerodynamic 3D shape of small-sized UAV wing at small flight speed and high lift coefficient, the optimization problem is set to minimize drag coefficient with fixed plane form and constant lift coefficient. The thickness of chordwise function is assumed to be given. The direct optimization problem must be solved by CFD methods with viscosity consideration in 3D flow that involves a great volume of computations which is feasible only to super computers [1, 6]. This chapter presents a combined direct inverse method that makes the optimization problem be feasible to ordinary PC.
