Abstract:
A disclosed gas turbine engine includes a fan including a plurality of fan blades rotatable about an axis, a bypass duct, a compressor section and a bypass ratio greater than 10. A combustor in fluid communication with the compressor section and a fan drive turbine in communication with the combustor. A gear system provides a speed reduction between the fan drive turbine and the fan and transfer power input from the fan drive turbine to the fan at an efficiency greater than 98%.

Claim (Index 25):
A gas turbine engine comprising:\n a fan including a plurality of fan blades rotatable about an axis; a compressor section; a combustor in communication with the compressor section; a bypass duct and a bypass ratio of a portion of air delivered into the bypass duct divided by the amount of air delivered into the compressor section is greater than ten (10); a fan drive turbine in communication with the combustor, the fan drive turbine comprising an inlet having an inlet pressure, an outlet prior to any exhaust nozzle and having an outlet pressure, a pressure ratio of the inlet pressure to the outlet pressure greater than about five (5); at least one bearing system supporting rotation of an inner shaft driven by the fan drive turbine and an outer shaft driven by a second turbine; a fan drive gear system having a sun gear driven by the inner shaft, a plurality of intermediate gears supported in a carrier a driven by the sun gear and ring gear circumscribing the intermediate gears, each of the intermediate gears supported by a bearing mounted to the carrier, the fan drive gear system providing a speed reduction between the fan drive turbine and the fan of greater than 2.3, the fan drive gear system transferring power input from the fan drive turbine to the fan at an efficiency greater than 98% and less than 100%; a lubrication system providing lubricant to the gear system and one or more other rotating components of the engine and removing thermal energy from the lubricant circulated through the fan drive gear system and the other rotating components, wherein the lubrication system includes a maximum capacity for removing thermal energy from lubricant circulated through the fan drive gear system and the other rotating components at a rate equal to no more than about 2% of power input into the fan drive gear system by the fan drive turbine during operation of the engine.
