The objective of the Advanced Transmission Components Investigation Program was to conduct development testing on selected critical components for a helicopter advanced transmission which could enter engineering development in the 1980-90 timeframe. Under this contract, advanced transmission components have been designed, analyzed, and tested with the aim of reducing drive system weight and cost, increasing reliability, and improving other important attributes. The work reported in this volume includes the evaluation of VASCO-X2 steel as a bearing material, design and test a ribbed-cup tapered-roller bearing with integrated inner race and shaft, test of a magnetic seal design, and development of an advanced finite-element analysis of complex bearing structure. The aims and objectives of each component development have been formulated and are compared against test results to develop a measure of improvement to be expected when these developments become operational.
