New Tapered Composite Spar Design

Abstract

The purpose of this study was to design and evaluate a filament winding approach to the fabrication of a spar which tapered in planform and thickness. A cost and weight comparison was made with a conventional titanium spar design and an alternative composite design. The design included the integration of a suitable root end retention fitting.
