Airfoil-Shaped Body Having Composite Base Skin with Integral Hat-Shaped Spar

摘要

An airfoil-shaped body (such as a wing or a flight control surface) comprising a base assembly made of composite material, which 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 comprise 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.
