<p>A flexbeam (10) for a soft inplane bearingless main rotor assembly (100) has six spanwise regions: a hub attachment region (12); a first tapered region (14); a second tapered region (16); a pitch region (18); a tapered outboard transition region (20); and a main rotor blade, torque tube attachment region (22). One described embodiment of the flexbeam is fabricated from continuous unidirectional fiber-glass plies having a 0° fiber orientation, unidirectional fiberglass plies of varying lengths having a 0° fiber orientation, and graphite cross plies having ± 45° fiber orientation. The distributed arrangements of ply endings cause kick loads in the flexbeam to be distributed relatively uniformly into the ply buildups.</p> |
