How This Is Calculated


$$ AR = \frac{s}{c} $$ where:

α   =   Aspect ratio   (Dimensionless)

s   =   Span   (m)

c   =   Chord length   (m)


Assumptions


  • Flow is steady and two dimensional.
  • Fluid is incompressible.
  • Foil is thin.
  • Viscous effects are ignored.
  • Angle of attack is below stall angle.
