Abstract : Work was performed to ascertain the operational suitability of the 6Elastic Pitch Beam Tail Rotor6 and to select an optimized coating system and leading edge erosion guard. The five basic tasks performed are the following: (1) protective coating for the glass reinforced plastic spar (GRP). (2) Elastic pitch beam spring rate. (3) Elastic pitch beam fatigue. (4) Erosion protection system. (5) Damage resistance and ballistic damage tolerance. (Author, modified-PL)
