Matched stiffness rotor flexbeam and blade system |
摘要 |
A flexbeam having matched in-plane and out-of-plane stiffness is described extending at least partway between the tips of a pair of rotor blades bonded thereto. The flexbeam so constituted produces a blade system with a primary in-plane frequency less than the primary forcing frequency. The matched stiffness of the flexbeam is provided by admixing, either compositionally or by laminating, materials of differing flexibilities to produce a high damping material of symmetrical stiffness.
