Abstract
Official abstract text for this publication.
Apparatus and methods provide for utilizing continuous curved composite stringers to control the loads and corresponding moments within curved regions of an aircraft or other vehicle without delamination or other interlamina failures. According to embodiments described herein, any number of tapered height curved composite stringers may be coupled to continuous skin components to create a curved continuous panel. The tapered height curved composite stringers may have webs that taper to a reduced height within curved regions and corresponding base flanges that widen during web tapering. Reinforcement fittings may be coupled to the base flanges in the curved regions for further strengthening and to provide for the attachment of supplemental panels to the stringers.
First claim
Opening claim text (preview).
What is claimed is: 1. A continuous structural panel, comprising: a continuous skin component; and a continuous curved composite stringer having a base flange coupled to the continuous skin component, and a web projecting outward from the base flange to create a web height, wherein the web tapers at a curved region of the continuous composite stringer, and wherein the base flange extends away from the web to create a base width that increases as the web height decreases.…
