Winglet Friction Coefficient Calculator

The winglet friction coefficient measures the resistance or drag experienced by winglets on an aircraft due to frictional forces as they move through the air. Unlike widely discussed aerodynamic parameters, standardized values for winglet friction coefficients are not prevalent. Research and discussions in aerodynamics often focus on broader aspects of winglet performance, such as drag reduction and improved lift-to-drag ratios. The formula to calculate Winglet friction coefficient as follows:

Where:

  • : Winglet Friction coefficient
  • : Winglet Reynold’s Number
