ABSTRACT:
An aircraft spoiler system consisting of semi-circular rods disposed within the leading edge of an aircraft wing and rotatably carried thereby so that in the inactive position the substantially flat surfaces are flush with the wing surface and in its most active position the flat surfaces are at right angles to the wing surface with approximately half of the rods extending above the wing surface, acting in a manner to eliminate the lift of the wing, i.e., as spoilers. The rods are controlled by a pair of magnetic clutches which connect the spoiler rods to a rotary solenoid when a toggle switch is thrown by the pilot. The spoilers have mechanical spring returns which automatically retract them when the switch is in its "off" position or in the event of a power failure. A retro-fit mounting is provided for fitting the spoilers on existing wing section.
