Embodiment approach

[0065]According to one embodiment, the manufacturing method comprises the steps of: placing a first plurality of fabric layers onto a surface of a base tool having recesses configured to shape a hat spar; placing a core on top of the first plurality of fabric layers placing the shaft into the recess; placing the two fills and the second plurality of fabric layers over the mandrel and adjacent portions of the first plurality of fabric layers; placing the baffle over the second plurality of fabric layers; Placing a vacuum bag over the baffle; evacuating a space between the vacuum bag and the base tool; infusing resin into the first plurality of fabric layers and the second plurality of fabric layers; and curing the infused resin.

[0066] According to one embodiment, a manufacturing method comprises the steps of: placing a plurality of braids onto a surface of a base tool having a recess configured to form a hat spar; placing a mandrel on top of the plurality of braids in the rec...

Abstract

The present invention relates to an airfoil-shaped body having a composite base skin with integral hat-shaped spar. The airfoil-shaped body (such as a wing or a flight control surface) comprises a base assembly made of composite material, and the base assembly in turn comprises a base skin and one or more hat-shaped spars integrally formed with the base skin. The airfoil-shaped body further comprises a close-out skin that is attached to the hat-shaped spars using fasteners. The method for manufacturing such an airfoil-shaped body uses a resin infusion process.

Description

technical field [0001] The technology disclosed herein relates generally to airfoil bodies for aircraft, and more particularly to wings and flight control surfaces for aircraft. Background technique [0002] Movement of the aircraft in different directions can be controlled using flight control surfaces. For example, flight control surfaces may be used to rotate the aircraft to change the pitch, roll, and yaw of the aircraft. In addition, the flight control surfaces can also be used to vary the lift coefficient of the wings on the aircraft. A flight control surface may be, for example but not limited to, an aileron, elevator, rudder, spoiler, flap, slat, vaporizer, elevator trim, or some other suitable type of control surface. [0003] For example, flaps are high-lift devices of the type used to increase the lift of an aircraft wing at a given airspeed. Flaps are usually mounted on the trailing edges of the wings of fixed-wing aircraft. These flaps are commonly used to r...
