摘要

The laminar flow technology is the core technology for the future development of "green aviation", and its huge drag reduction potential makes it a research hotspot in the aviation field. This article starts from the physical characteristics of flow and the nature of transition phenomena of jet airliners, and expounds the realization principle and application scope of the NLF and HLFC technology. The global research status and development trend of the NLF/HLFC technology are reviewed. Focusing on the cutting-edge issues of the CFD-based laminar flow wing design technology, we systematically discuss the laminar flow from multiple levels of engineering application-oriented transition prediction methods, gradient-free/gradient-based optimization methods, uncertainty analysis and the robust optimization method. Meanwhile, the similarities and differences between the laminar flow wing aerodynamic design and full turbulent aerodynamic design are discussed, and the aerodynamic design theories of the NLF and HLFC wing are then sorted out. Finally, based on the development trend of the jet airliner technology, the problems faced by the laminar flow design technology are summarized, and the future development direction and suggestions for the aerodynamic optimization design technology of laminar flow wings are presented.
