Preliminary Design Study of a Composite Main Rotor Blade for the OH-58 Helicopter. Volume I. Trade Analysis and Preliminary Design Study of Composite OH-58 Main Rotor Blade.

Abstract

The objective of this program was to design a composite rotor blade for the OH-58C/A helicopter which has reduced life-cycle costs, 6% improved hover performance, improved reliability and maintainability, reduced radar signature and increased ballistic survivability. A trade-study approach was used to select the final configuration for the preliminary design phase. A monolithic composite structure evolved which utilizes winding in the production of the main spar, skins and the trailing edge spline. The blade satisfies basic objectives using a double-tapered planform and a VR-7 airfoil. Composite materials selected include S-glass, E-glass and carbon graphite.
