The thin-walled structure with lattice and stiffeners is a typical hybrid structure and effectively combines the load-bearing merits of lightweight lattices and thin-walled stiffened configurations, while demonstrating significant multifunctional potential that provides novel technical solutions for aerospace structural lightweighting. The increasing maturity of metal additive manufacturing technolo-gies has laid a reliable foundation for the practical application of lattice structures. To facilitate the implementation of lattice structures in aerospace engineering, this paper focuses on thin-walled structures with lattice and stiffeners, primarily from the perspective of load-bearing structural design and its practical applications. Building upon the joint team's recent exploratory applications, this paper systematically outlines four critical aspects: 1) Fundamental characteristics of lattice structures, 2) Macroscale mechanical analysis methodologies, 3) Design of the lattice Representative Volume Element (RVE), 4) Optimization design methodologies for thin-walled load-bearing structures with lattice and stiffeners. These systematic analyses aim to establish comprehensive reference guidelines for engineering designers. Furthermore, based on challenges encountered in aerospace, aviation, and aero-engine applications, this paper identifies priority research domains requiring urgent attention and critical technologies demanding breakthroughs in the hybrid struc-ture design, offering valuable insights for researchers in related fields.
