Abstract
The research progress of the design and evaluation technologies for the layout of the supersonic laminar flow is reviewed. Firstly, the engineering significance of improving the aerodynamic efficiency of supersonic aircraft cruise is given, and the composition of supersonic aircraft cruise drag is analyzed. Then, the research progress of the two effective methods for delaying flow transition in natural laminar flow design and flow control is described. The research progress of the approaches for supersonic transition numerical simulation, wind tunnel test and flight test evaluation are summarized. The typical layout design and evaluation cases for supersonic laminar flow at home and abroad are introduced. Finally, the difficulties in the technologies for laminar flow layout design and evaluation for supersonic aircraft are discussed, and suggestions for further development are given.
