FUNDAMENTAL GEAR SYSTEM ARCHITECTURE

摘要

A fan drive gear system for a gas turbine engine includes a gear system that provides a speed reduction between a fan drive turbine and a fan and a mount flexibly supporting portions of the gear system. A lubrication system supporting the fan drive gear system provides lubricant to the gear system and removes thermal energy produced by the gear system. The lubrication system includes a capacity for removing thermal energy equal to less than about 2% of power input into the gear system.

1. A fan drive gear system for a gas turbine engine comprising:
a gear system that provides a speed reduction between a fan drive turbine and a fan; and a lubrication system configured to provide lubricant to the gear system and to remove thermal energy produced by the gear system, wherein the lubrication system includes a capacity for removing thermal energy greater than zero and less than about 2% of power input into the gear system during operation of the engine.
