Rotary actuated high lift gapped aileron

Abstract

A rotary actuated high lift gapped aileron system and method are presented. A high lift gapped aileron couples to an airfoil at a hinge line and changes a camber of the airfoil. A rotary actuator coupled to the high lift gapped aileron produces a rotary motion of the high lift gapped aileron in response to an actuation command. A droop panel positioned over the hinge line enhances lift of the high lift gapped aileron. A cove lip door positioned under the hinge line provides an airflow over the high lift gapped aileron. A deployment linkage mechanism coupled to the high lift gapped aileron positions the droop panel and the cove lip door in response to the rotary motion.

Description

technical field [0001] Embodiments of the present disclosure relate generally to fluid dynamic design. More specifically, embodiments of the present disclosure relate to the design of fluid dynamic control surfaces. Background technique [0002] Typically, an aileron is a hinged flight control surface attached to the trailing edge of a fixed wing aircraft. The ailerons are used to control the roll of the aircraft, which causes a change in heading due to the tilt of the lift vector. The current trailing edge configuration utilizes a down-sloped spoiler to provide high / high lift through a single slotted flap, thus exhibiting Trailing Edge Variable Curvature (TEVC) functionality. In order to provide higher cruise performance, the wing aspect ratio becomes larger. A large wing aspect ratio results in a very long outboard flap span, usually requiring one or two heavy and expensive outboard flaps with many spoilers.
