The design, fabrication, and testing results of a low-radar-cross-section (LRCS) filament-wound composite tail rotor blade for the OH-6A helicopter are reported. Two tull-scale blades and four 12-inch-long blade sections were fabricated during the program. The blades and blade sections were all fabricated principally from Kevlar 49 roving/epoxy. The blades and blade sections all had sheets of microwave-absorbent materials laminated integrally with the windings to reduce the radar signature of the composite blade. (Modified author abstract)
