A report is made on the final phases of a program to evaluate a replacement for the main driveshaft coupling of the UH-1 helicopter. The candidate coupling is based on the Kaflex design principle which uses flexing metal elements instead of sliding contact members, eliminating the need for lubrication maintenance, and offering longer endurance life. The reported program phases are: Demonstration of a fail safe feature, bench endurance test, and flight testing. (Author)
