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 energy equal to less than about 2% of energy input into the gear system.
1. A gas turbine engine comprising: a fan including a plurality of fan blades rotatable about an axis;a compressor section;a combustor in fluid communication with the compressor section;a fan drive turbine in communication with the combustor, wherein the fan drive turbine has a first exit area at a first exit point and is configured to rotate at a first speed;a second turbine section including a second exit area at a second exit point and being configured to rotate at a second speed that is faster than the first speed, wherein a first performance quantit...
