Multi-section spoiler
Abstract:
An aircraft spoiler mechanism includes a spoiler fore-section, a spoiler aft-section, and a reverse-motion linkage arm. The spoiler fore-section includes a forward end, a hinge end, an actuator coupling, and a pivot coupling to couple to a wing structure of an aircraft to enable rotation of the spoiler fore-section relative to the wing structure. The spoiler aft-section includes a hinge portion coupled to the hinge end of the spoiler fore-section and a crank-arm. The reverse-motion linkage arm includes a first end, a second end, and a pivot point coupled to the forward end of the spoiler fore-section. The spoiler mechanism also includes a first linkage to couple the first end of the reverse-motion linkage arm to the wing structure and a second linkage coupled to the second end of the reverse-motion linkage arm and to the crank-arm on the spoiler aft-section.
