Flight Test of a Composite Multi-tubular Spar Main Rotor Blade on the AH-1G Helicopter, Volume I. Materials, Design and Test.

Abstract

The objectives of this program were to design a composite main rotor blade in the multi-tubular spar configuration to be directly interchangeable (in pairs) with the production metal (540) blades on the AH-1G helicopter, have increased fatigue life, invulnerability to the 23mm ballistic threat, low radar cross section, and low fabrication cost. Manufacturing technology was developed and described in a Process Specification. Laboratory, ground, and flight tests demonstrated that the wet-filament wound, co-cured blade met, and in some cases surpassed, all objectives and could be adapted for Army service. (Author)
