Abstract:
The purpose of the project was to determine the feasibility of operating power-transmission shafts at supercritical speeds. It was determined that supercritical speed operation was definitely feasible. By use of the proper damper to damp lateral vibrations of the shaft, shafts were operated through speed ranges including the 20th critical speed. Work was conducted to determine the relative importance of various parameters to shaft performance at critical speeds. The following factors were found to be of primary importance damper location, shaft mass eccentricity, damper weight, damper damping coefficient, damper moment restraint, and quality of shaft end connections such as universal joints. A preliminary design of supercritical shaft system for a Vertol Chinook helicopter was made. A design manual was written summarizing the design procedure for supercritical shaft systems.
