FUNDAMENTAL GEAR SYSTEM ARCHITECTURE

摘要

A fan drive gear system for a gas turbine engine (20) includes a gear system (48) that provides a speed reduction between a fan drive turbine (46) and a fan (42) and a mount (76) flexibly supporting portions of the gear system (48). A lubrication system (98) supporting the fan drive gear system (48) provides lubricant to the gear system (48) and removes thermal energy produced by the gear system (48). The lubrication system (98) includes a capacity for removing energy equal to less than about 2% of energy input into the gear system (48).
