A new generation of transport aircraft will be powered by efficient, advanced turboprop propulsion systems. Systems that develop 5000 to 15000 horsepower have been studied. Reduction gearing for these advanced propulsion systems is discussed in this paper. Allison Gas Turbine Division experience with the 5000 horsepower reduction gearing for the T56 engine is reviewed and the impact of that experience on advanced gear systems is considered. Gear system arrangements are analyzed, including single- and counter-rotation types. The reliability needs for component design and development are also considered. Allison's experience and their research serve as a basis on which to characterize future gear systems that emphasize low cost and high reliabiliity.
