Abstract:

Supercritical shaft operation was studied using a 38-in. diameter 124-in. long aluminum shaft subjected to torque, curvature, and axial force. Damping coefficients for both the full-scale shaft of the Vertol Chinook helicopter and a dynamic model shaft were derived, and a design for the Chinook damper was developed. Digital computer work established the effects of moment restraint on shaft critical speed. The laboratory setup necessary to measure the damping coefficient of the experimental shaft dampers was completed, as was the setup which will be used to study the effects of external vibration on shaft operation.
