  • Canard control system for aircraft
    Patent number: 4848700
    Abstract: A system with a canard disposed in a cage with canard fore and aft movement within the cage for trimming purposes. Rails support the cage and include both horizontal and inclined segments with the cage and canard inclined by the latter segments to increase the canard angle of attack to preserve the canard-stallfirst characteristic of the aircraft. A combined canard and flap control assures automatic advancement and inclining of the canard to counteract forward pitching of the aircraft caused by flap deployment.
