Cove lip door slaved to trailing edge control device

摘要

A primary flight control device for an aircraft, such as a flaperon attached to an aircraft wing, utilizes independent yet interactive airgap control systems designed to avoid weight penalties associated with conventionally used cam and track systems. An actuator directly controls movements of the flaperon; the flaperon motion is then used to slave separate movements of secondary flight control devices, such as a flaperon hinge panel and a cove lip door, to various positions of the flaperon for indirect control of aerodynamic air gaps during flight. The use of a bell crank for indirectly slaving the flaperon hinge panel movements to the flaperon avoids conventionally used cam and track systems. Although the cove lip door utilizes a separate linkage system, the bell crank and cove lip door linkage systems work in conjunction to assure desired aerodynamic airflows over the aircraft wing and flaperon structures.

主权项

1. An aircraft wing configured to be fixed to and extend from an aircraft fuselage, the wing having a leading edge;
a trailing edge; a primary control device attached to the trailing edge, a linear actuator in communication with the control device, and an aircraft input controller in communication with the linear actuator, wherein movement of the primary control device is subject to the linear actuator via the input controller; a bell crank mechanism coupled to a secondary control device, and configured to link movement of the linear actuator indirectly to movement of the secondary control device, and a moveable aerodynamic cove lip door proximal to the primary control device, the cove lip door separately attached to the trailing edge via a cove lip door hinge coupled to an actuator pivot link, the actuator pivot link also attached to the trailing edge; wherein movement of the cove lip door is an indirect function of movement of the primary control device.
