Wing Design

Although the RingWing wings are of unusual shape, their cross-sections are a standard airfoil (S2091), chosen because that airfoil has very consistent behaviour over a wide range of Reynolds numbers. Of course that result is for a long straight wing, and the RingWing has wings that are neither long nor straight. So we have experimentally tested these wings.

The model wings have been tested at air-speeds up to 40m/s in order to determine

  • Whether the model results can be scaled to predict the behaviour of a larger aircraft.
  • Values of the basic wing lift and pitching-moments.

Results can be found here.
