摘要：
The laminar wing technology can reduce the drag of the aircraft significantly. Selection of laminar wing parameters is affected by the overall parameters of the aircraft. Collaborative design of the laminar wing with its high-lift devices also needs to be carried out. Firstly, the clean airfoil of cruise configuration and the multi-segment airfoil of landing configuration are optimized by using leading-edge Kruger flaps and trailing-edge Fowler flaps. On this basis, the aerodynamic design for the three-dimensional laminar wing and its high-lift devices is realized through combination of RANS calculation of free transition and the efficient multi-level optimization based on the response surface. © 2022 AAAS Press of Chinese Society of Aeronautics and Astronautics.
