Abstract Lightweight, high stiffness and high strength structures are the key elements to achieving high speed, long range and strong aircraft manoeuvrability. In recent years, fundamental research and design technology development on innovative design methods, such as structural topology optimization and bionic design, have provided powerful design tools for the design of high-speed aircraft structures. This paper first analyzes the design requirements of high-speed aircraft structures. Then reviews the related research on the integration method of structural topology optimization, bionic design and additive manufacturing at domestic and abroad in recent years from the perspectives of research methods and classification applications. Finally summarizes the main problems in the innovative design methods and applications of aircraft structures, and proposes the key breakthrough technologies in the near future, thus providing a reference for the structural design of the new generation high-speed aircraft.
