Abstract
Official abstract text for this publication.
A bell crank mechanism is configured to at least indirectly link movement of an aircraft wing spoiler-like hinge panel to the movement of a primary flight control device on an aircraft wing trailing edge. The aircraft wing is configured to be fixed to and to extend from an aircraft fuselage, the wing including a leading edge and a trailing edge. The primary flight control device is attached to the trailing edge, and any movement of the control device is directly subject to an aircraft input controller by a linear actuator. The moveable aerodynamic hinge panel, a secondary control device, is situated proximally to the primary flight control device, and the hinge panel is separately attached to the trailing edge. The bell crank mechanism slaves any hinge panel motion to movements of the primary control device.
First claim
Opening claim text (preview).
What is claimed is: 1. A bell crank mechanism secured to an aircraft wing, the wing having a leading edge and a trailing edge, and having a primary control device attached to the trailing edge, and a movable aerodynamic hinge panel being separately attached to the trailing edge, the hinge panel being a secondary control device; wherein the bell crank mechanism comprises: a plurality of links serially coupled together, each link having a pivot coupling at each end, the pivot coupli…
