Abstract:
A gas turbine engine comprises a fan for delivering air into a bypass duct as bypass flow, into a core housing as core flow, with the core housing containing an upstream compressor rotor and a downstream compressor rotor. An overall pressure ratio is defined across the upstream and downstream compressor rotors. A bypass ratio is defined as a volume of air delivered as bypass flow compared to a volume of air delivered into the core housing. The overall pressure ratio is greater than or equal to about 45.0, and the bypass ratio is greater than or equal to about 11.0.

Claim (Index 23):
The method as set forth in  claim 22 , wherein:\n the step of driving said upstream and downstream compressor rotors establishes a ratio of a tip speed at said downstream compressor rotor compared to a tip speed at said upstream compressor rotor that is less than or equal to 1.18 and is greater than or equal to 1.0; and the step of driving said fan occurs for a duration of said flight length, said flight length including a first time at a low power cruise condition and a second time at a climb condition and a take-off condition, and a ratio of said first time to said second time being at least 15:1.
