Title:
LEADING-EDGE SLAT DEVICE
Document Type and Number:
Japanese Patent JPS62157895
Kind Code:
A
Abstract:
An aircraft leading edge slat (11) is biased when at an extended location toward a first position wherein the trailing edge (19) of the slat is a predetermined distance from the wing upper surface. The slat is pivotable to a second position, when aerodynamic forces acting on the wing overcome the biasing force, wherein the slat trailing edge is pivoted upward and forward and the distance between the slat trailing edge and the wing upper surface is increased. The slat is retracted and extended by a drive track (12) which is supported inside the wing by upper rollers (18) located chordwise within the wing cavity, a lower front roller, and a pair of roller rings (90) rotatably mounted at opposite sides of a rotary actuator pinion gear (86). The pinion gear engages the drive track and moves the slat between the extended and retracted positions.
