Abstract:

Aircraft aerodynamic configuration design has long adhered to an experience-driven design philosophy,where the aerodynamic performance of the baseline shape often determines and limits the performance improvements achievable through shape optimization.This traditional design approach is incapable of yielding disruptive aerodynamic configurations.In recent years,with the emergence of aerodynamic topology design concepts,aerodynamic topology optimization methods have gained attention and are expected to be applied to the design of novel aircraft aerodynamic configurations.Focusing on aerodynamic topology optimization methods,this paper reviews their development in terms of topology representation methods and optimization algorithms,and analyzes typical application cases of existing methods in the design of novel aircraft aerodynamic configurations.First,the historical development of aerodynamic topology optimization methods is outlined.Second,recent advances in the application of aerodynamic topology to novel aircraft configuration design are summarized.Subsequently,the challenges and difficulties faced by aerodynamic topology optimization methods are discussed,including difficulties in handling high-speed compressible turbulent flows and insufficient smoothness at fluid-solid interfaces in aircraft flow topology.Finally,future research directions in this field are prospected.
