An inverse design method with aerodynamic design optimization for wing glove with hybrid laminar flow control
Abstract The design of the hybrid laminar flow control (HLFC) system involves the comprehensive design of the suction control and the profile, and it has become an urgent problem for a three dimensional shape design with the consideration of HLFC technology, especially in condition of the high Reynolds number with the large sweep angle. In order to deal with this issue, this paper conducts an inverse design method combining a design optimization oriented by pressure distribution. This methodology prescribes a target pressure distribution and then uses the optimization method to pursue the corresponding shape that matches the target pressure distribution. The optimization framework is mainly based on the particle swarm optimization algorithm and the Kriging surrogate model. The studied model is a wing glove, and the results show that the desired robust wing glove that meets the engineering requirements can be efficiently obtained. The optimized wing glove has a long enough laminar zone with the help of suction control, and it shows good robustness with the variation of sideslip angles and angles of attack.
