Rotary actuated high lift clearance ailerons

Abstract

The present invention provides a rotationally actuated high lift clearance aileron system and method. High lift clearance ailerons are coupled to the airfoil at the hinge line and change the camber of the airfoil. A rotary actuator coupled to the high lift clearance aileron causes rotational movement of the high lift clearance aileron in response to an actuation command. A downslope panel located above the hinge line increases lift for high lift clearance ailerons. Baffles located below the hinge line provide airflow over the high lift clearance wing. Deployment linkages coupled to the high-lift clearance wing position the downtilt panels and baffles in response to rotational 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.
