Abstract:

The report presents effort on the bench testing and analytical description of a full-size supercritical-speed shaft designed for installation in the CH-47 helicopter. A full-size shaft was built, and shaft damper was developed to meet the requirements of the system as installed in an aircraft. The bench test program included tests of the damper, torsional fatigue tests of the redesigned adapter fittings, and dynamic tests of the full-size supercritical-speed shaft.
