Slot-cum-aileron control

Slot-cum-aileron control


  •  The slots, which need only be at the outer portions of the wings in front of the ailerons, may be of the automatic type, or the slot may be interconnected to the aileron in such a way that when the aileron is lowered the slot is opened.
  •  while when the aileron is raised, or in its neutral position, the slot is closed. By this means the down-going aileron will certainly serve to increase the lift for several degrees beyond the stalling angle, nor will the drag on this wing become very large since the open slot will lessen the formation of eddies.
  •  We shall therefore obtain a greater tendency to roll in the right direction and less tendency to yaw in the wrong direction. This is exactly what is required, and the system proved to be very effective in practice.
