The Reynolds number effect presents a critical technical challenge in the design of large aircraft
significantly impacting flight safety
aerodynamic performance
development efficiency
and cost. This paper first introduces the primary research methodologies employed to study Reynolds number effects from the perspective of large aircraft design and development
consisting of wind tunnel testing and numerical simulation. Subsequently
the influence patterns of Reynolds number effects on key aerodynamic components are analyzed
including supercritical airfoils/wings
full-configuration aerodynamic design
low-speed high-lift devices
winglets
and vortex generators. Concurrently
the paper reviews research progress on the flow mechanisms associated with these Reynolds number effects. Furthermore
several potential solutions to address Reynolds number effect challenges are elaborated
encompassing advanced wind tunnel testing techniques
data correction methods
and artificial intelligence technologies. Finally
the paper summarizes existing research achievements and identifies current limitations concerning Reynolds number effects. Based on this assessment
specific recommendations for future research directions are proposed.
