Web5 Oct 2011 · The relative thickness is the "thickness/chord ratio" (t/c ratio) and is the maximum thickness of the aerofoil expressed as a percentage of the chord. If you have a wing of say 8% t/c ratio and it has a chord of say 10 feet (120 inches) then the point of maximum thickness will be 9.6 inches. (8% of 120 inches = 9.6) WebIn this paper we examine the design of metallic and composite aircraft wings in order to assess how the use of composites modifies the trade-off between structural weight and drag.
