The report describes the evaluation to determine the effects of static loading, cyclic loading and ballistic damagerepairs on the stiffness and resonant behavior of three full-scale, filament-wound tubular- reinforced UH-1D main rotor blades. Blades tested were fabricated from glass fiber and Kevlar 49. Detailed test results are provided which reflect the suitability of the tubular design for rotor blades.
