Structural composite airfoil with directly coupled front spar, and related methods

摘要

PROBLEM TO BE SOLVED: To provide a structural composite airfoil portion and a related method. A structural composite airfoil is a primary structural element, a secondary structural element defining the trailing edge of the structural composite airfoil, and a leading edge skin panel defining the leading edge of the structural composite airfoil. including. Primary structural elements include an upper skin panel, a lower skin panel, and a front C-channel spar. The first channel of the anterior C-channel spar faces the leading edge of the structural composite airfoil, and the upper flange of the anterior C-channel spar forms an acute angle with the elongated span of the anterior C-channel spar. The leading edge skin panel is placed adjacent to the leading edge area of the primary structural element, the first end area of the leading edge skin panel is coupled to the upper flange of the front C channel spar, and the second end area. Is coupled to the lower flange of the leading C channel spar. [Selection diagram] Fig. 2
