摘要： A composite wrap is provided for damping vibration in an elongated quill shaft having a cylindrical body. The composite wrap includes interior layering for disposition about a cylindrical body, exterior layering configured to define an exterior composite wrap shape and sequential cured-in-place, vibration damping, fibrous epoxy layers. The sequential cured-in-place, vibration damping, fibrous epoxy layers are radially interposed between the interior and exterior layering to dampen vibrations of and/or to adjust a resonance frequency of the cylindrical body.

摘要： A connection between a first component and a second component is provided including a first hole formed in a portion of the first component and a second hole formed in a portion of the second component. The second hole is aligned with the first hole. A pin includes a through hole having a pin hole diameter. The pin extends through a portion of the first hole and into a first portion of the second hole. The pin is configured to absorb a shear load applied to the connection. A bolt extends through the second hole and the pin such that a clearance fit is formed between the bolt and the pin. The bolt is configured to absorb an axial load applied to the connection. A nut connected to the free end of the bolt limits movement of the bolt relative to the first and second component.
