Embodiment Construction

[0027] In the following description, many specific details are stated for a thorough understanding of the present disclosure. However, it will be apparent to those of ordinary skill in the art that the invention disclosed herein can be practiced without these specific details. In other cases, specific numerical designations may be adopted, such as "first wing". However, the specific numerical numbers should not be interpreted as a literal order, but should be interpreted as "the first wing" is different from the "second wing". Therefore, the specific details stated are merely exemplary. Specific details may differ according to the spirit and scope of the present disclosure, and can still be conceived as being within the spirit and scope of the present disclosure. The term "coupled" is defined as the meaning of directly connecting to the component or indirectly connecting to the component through another component. In addition, as used herein, the terms "about", "approximatel...

Abstract

Disclosed are apparatus and method for an actuator system to modify an adaptive flap of an aircraft wing. The system may include: a drive rod extending from a nose portion of the flap to an interior thereof; a bell crank, which is attached to the interior and configured to receive an end of the drive rod; a pivot, which is disposed opposite of the drive rod may couple the bell crank to a mount fixed to a lower surface of a trailing edge portion of the flap; a skin overlap, which may be configured to allow the lower surface of the trailing edge portion to slide adjacent to a lower surface of aremaining portion of the flap under the action of the drive rod; and a bumper, which may be disposed within the aircraft wing and configured to exert a continuous force on the drive rod when the flapis moved to a retracted state.

Description

[0001] priority [0002] This application claims priority to the U.S. Provisional Application No. 62 / 318,132 entitled "Actuator For Adaptive Airfoil" filed on April 4, 2016, the full text of the provisional application Incorporated into this article by reference. Technical field [0003] The field of the present disclosure relates generally to aerospace vehicle systems. More specifically, the field of the invention relates to systems and methods for changing the shape of airfoils. Background technique [0004] The current aircraft design utilizes various airfoils on wings, horizontal stabilizers, canards, rotor blades, vertical stabilizers, and various other structures mainly composed of relatively fixed airfoil surfaces. Generally, the flight surface must be optimized for specific applications, such as low-speed maneuverability aerodynamics or improved high-speed aerodynamics. Aircraft configured to operate in several performance environments must generally adopt airfoil surface...
