Numerical optimization of low-Reynolds number, long-endurance airfoils has been investigated with an adjoint Navier Stokes aerodynamics shape optimization method, and an experimentally verified inverse approach. The optimized airfoils are compared with the inverse result and an existing airfoil. The optimized airfoils show significantly increased maximum lift coefficient and endurance factors, together with improved pitching moment and reasonable thickness distributions.
