Thin airfoil theory formula

WebThe general equation for the boundary condition is Eqn. (6.5), which we write slightly differently as: vi ⋅ ni = −U ⋅ni (6.6) (6.6) v i ⋅ n i = − U ⋅ n i Where vi v i is the induced velocity by the set of vortices evaluated at each panel j j and ni n i is the panel outward normal. Web18 May 2024 · The thickness of the airfoil is a very important design parameter and as always expressed as a percentage of the total chord. The airfoil plotted above has a thickness-to-chord ratio of 12%. This means that the height at the thickest section is equal to 12% of the total chord.
