Aircraft gas turbine engines operate at speeds ranging from 10,000 to 30,000 rpm. to harness this power and to operate at desired output speeds, the industry relies on the use of high speed transmission systems. as powers and speeds of theengines are increasing, the gear industry has responded to to… More

Traditionally, shipboard power generation is accomplished via auxiliary engines and generator sets. significant cost advantages can be projected if this electrical demand could be met by extracting power from the ship's prime mover. to accomplish this, and to maintain a constant frequency on… More

Cost of cargo handling operations can be reduced by equipment that uses less time and energy to perform and randrequires less manpower to operate, monitor, and maintain. one objective of this proposal is to evolve a preliminary design of a representative piece of machinery, namely a mooring/warping… More
