Research progress on aerodynamic stealth design technology of aircraft
Aerodynamic stealth design is a key technology for aircraft to realize efficient combat in high-risk environ-ments,and it has been a hot technology researched by aviation powers for a long time.This paper combines the group's many years of experience in aerodynamic stealth design and the demand for aerodynamic stealth design in re-cent years,summarizes and analyzes the development history and current research status of the aerodynamic stealth design of overall aerodynamic layout,the aerodynamic stealth design of wing and the aerodynamic stealth design of air intake and exhaust system.According to the current research status,three key technologies for comprehensive and optimal aerodynamic stealth design are sorted out:efficient parameterization technology for complex shape,aerodynamic stealth refinement design technology,and integrated aerodynamic stealth design technology for inter-nal and external flow.Finally,combined with the design requirements of aerodynamic stealth for future aircraft,four key research directions are expected:aerodynamic electromagnetic infrared integrated stealth design,aerody-namic stealth design considering coating,aerodynamic/stealth structure integrated design,and active flow control stealth integrated design.
