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 19):
A gas turbine engine according to  claim 1 , wherein:\n a turbine entry temperature (T0turb_in) is defined as the temperature (K) at the inlet to an axially most upstream turbine rotor in the gas turbine engine at a maximum power condition of the gas turbine engine; a core size is defined as Wcomp_in \u00b7 T \ue89e \ue89e 0 \ue89e comp_out P \ue89e \ue89e 0 \ue89e comp_out where: Wcomp_in is the mass flow rate (kg/s) at entry to the engine core; T0comp_out is the stagnation temperature at exit to the compressor; P0comp_out is the stagnation pressure at exit to the compressor; and a thrust to core efficiency ratio TC is at least 1.5\u00d710 7  kNkg \u22121  sPa, where the thrust to core efficiency ratio is defined as TC = ( Max \ue89e \ue89e Net \ue89e \ue89e Thrust \ue89e \ue89e at \ue89e \ue89e Sea \ue89e \ue89e Level ) \u00b7 T \ue89e \ue89e 0 \ue89e turb_in CS .
