Test Results of the RAH-66 Main Rotor Ballistically Damaged Flexbeam.

Abstract

The AATD supplied, ballistically damaged, RAH-66 main rotor blade flexbeam was tested in fatigue to demonstrate fly home capability. The testing was conducted in the Bearingless Main Rotor test facility, and consisted of loads representative of 45 degree AOB turns at Vibratory test loads including flatwise, chordwise and torsional moments, centrifugal load and snubber/damper loads. The requirement was to demonstrate 30 minutes capability. The results demonstrated a total of 90 minute flight capability of the ballistically damaged flexbeam, thus exceeding the 30 minute fly home capability requirement.
