Abstract:
A highly efficient gas turbine engine includes a fan which is driven from a turbine via a gearbox, such that the fan has a lower rotational speed than the driving turbine, thereby providing efficiency gains. The efficient fan system is mated to a core that has low cooling flow requirements and/or high temperature capability, and which may have particularly low mass for a given power.

Claim (Index 14):
A gas turbine engine according to  claim 1 , wherein:\n a bypass duct is defined radially outside the engine core; part of a flow that enters the engine core bypasses the combustor and is used as turbine cooling flow to cool the turbine, which includes the first turbine and the second turbine; and at cruise conditions, a cooling to bypass flow efficiency ratio, defined as the ratio of a mass flow rate of the turbine cooling flow to a mass flow rate of flow through the bypass duct, is less than 0.02.
