The invention is a spoiler device for an aircraft having a leading edge slat (50) mounted on at least a portion of the leading edge of the wing of the aircraft. A rear portion (52) of the leading edge slat (50) is rotatably mounted thereto and movable from a retracted position to an extended position (52') so as to act as a spoiler. A latch mechanism comprising links 56, 60, 68 and spring member (76) which yieldably hold the rear portion (52) of the slat (50) in the retracted position. An actuator (80) is provided which is mounted to the wing and which is in detachable contact with the latch mechanism of the slat (50). Upon actuation the rear portion (52) is extended and is returned to the retracted portion by the spring member (76). The actuator (80) can be either mechanical, pneumatic, hydraulic or electrical.

1. A spoiler device for an aircraft, said aircraft having a leading edge slat mounted on at least a portion of the leading edge of the wing of said aircraft, said slat moveable from a retracted position to an extended position, said spoiler device comprising: a rear portion of said slat rotatably mounted thereto moveable from a retracted position, to an extended position so as to act as a spoiler; biasing means adapted to yieldably hold said rear portion of said slat in said retracted position; and actuation means mounted on said wing in detachable contact with said rear portion of said slat, said actuation means adapted to extend said rear portion when said slat is in said retracted position. 2. The spoiler device of claim 1 wherein said biasing means is a spring coupled on one end to said moveable rear portion and on its opposite end to said nonpivoting portion of said spoiler. 3. The spoiler device of claim 2 wherein said actuation means is an actuator selected from the group consisting of mechanical, pneumatic, hydraulic, or electrical actuators having a probe in detachable contact with said rear portion of said slat. 4. A spoiler device for an aircraft, said aircraft having a leading edge slat mounted on at least a portion of the leading edge of the wing of said aircraft, said slat moveable from a retracted position to an extended position, said spoiler device comprising: a top rear portion of said slat pivotly mounted to said slat having first and second ends; a bottom rear portion having an aperture therethrough said bottom rear portion rigidly attached to said slat; a first link having first and second ends, said first end attached to said top rear portion of said slat; a second link having first and second ends said first end rotatably coupled to said second end of said first link; a third link having first and second ends said first end of said third link abutting a protrusion on said bottom rear portion of said slat, said second end of said third link pivotly coupled to said second end of said second link; biasing means coupled between said second and third links causing said links to be in a overcenter relationship preventing movement of said top rear portion; and actuation means mounted to said wing adapted to move said second and third links out of said overcenter relationship and to cause said top rear portion to move to said extended position. 5. A spoiler device of claim 1 or 2 or 3 or 4 wherein said actuation means comprises: a housing mounted in said wing having an aperture therethrough said aperture having a longitudinal axis; a guide member moveably mounted within said aperture of said housing; a probe pivotly mounted to said guide means; a detent means mounted in said guide member adapted to yieldably hold said probe in alignment with said longitudinal axis of said aperture; means mounted to said housing to limit the degree of pivoting of said probe; linkage means rotatably mounted to said housing and coupled to said guide member, said linkage means adapted to move said guide member toward the rear portion causing said probe to contact and move said rear portion to said extended position.
