Differential ailerons

 Differential ailerons

  • Here, again, is a delightfully simple device suffering only from the same defect that, although it provides a step in the  right direction, it does not go far enough to satisfy our needs.
  • Instead of the two ailerons moving equally up and down, a simple mechanical arrangement of the controls causes the aileron which moves upwards to move through a larger angle than the aileron which moves downwards.
  • the idea being to increase the drag and decrease the lift on the wing with the up-going aileron, while at the same time the down-going aileron.
  • owing to its smaller movement, will not cause excessive drag.
