Abstract:
A gas turbine engine includes a gear system that transfers power input from a fan drive turbine to a fan through a gear system with a gear reduction ratio greater than 2.3. A flexible mount supports the gear system and accommodates movement of the gear system relative to an engine static structure. A lubrication system provides lubricant flow to a plurality of rotating components including bearing systems and the gear system and has a maximum capacity for removing thermal energy less than or equal to no more than 2% of power input into the gear system.

Claim (Index 1):
A gas turbine engine comprising:\n a fan including a plurality of fan blades rotatable about an axis; a fan pressure ratio across a fan blade alone of less than 1.45; a bypass duct; a compressor section; a bypass ratio greater than (ten) 10, the bypass ratio being defined as the portion of air delivered into the bypass duct divided by the amount of air delivered into the compressor section; a combustor in communication with the compressor section; a fan drive turbine in communication with the combustor, the fan drive turbine comprising a pressure ratio greater than about 5, wherein the fan drive turbine further includes an inlet having an inlet pressure, and an outlet that is prior to any exhaust nozzle and having an outlet pressure, and the pressure ratio of the fan drive turbine is a ratio of the inlet pressure to the outlet pressure; a gear system providing a speed reduction between the fan drive turbine and the fan and transferring power input from the fan drive turbine to the fan at an efficiency greater than 98%, wherein the gear system further comprises a gear reduction ratio of greater than 2.3; a mount flexibly supporting the gear system through the static structure of the engine and accommodating movement between the gear system and the static structure; a lubrication system providing lubricant to a plurality of rotating components of the engine, including the gear system, and removing thermal energy from the lubricant; and a load limiter constraining movement of the gear system during an unbalanced load condition; wherein the load limiter constrains radial loads and torsional loads within defined limits.
