An optimal wing planform and winglet reduces the wing drag while having good handling qualities. Our optimization software WingPlanform combines a new geometry parameterization method with a in-house developed extended version of the DLR software Lifting_Line, capable of considering nonlinear viscous decambering effects. Stationary and instationary flight conditions can be considered including trim calculation for control surface deflections during the optimization run. With this, we design your wing planform shape, your retrofit winglets or your propeller – visually pleasing and aerodynamically performant.
