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 1):
A gas turbine engine for an aircraft comprising:\n an engine core comprising:\n a turbine, a combustor, and a compressor, the turbine comprising a first turbine and a second turbine and the compressor comprising a first compressor and a second compressor; \n a first core shaft connecting the first turbine to the first compressor; \n a second core shaft connecting the second turbine to the second compressor, the second turbine, second compressor, and second core shaft being arranged to rotate at a higher rotational speed than the first core shaft, the gas turbine engine further comprising: \n a fan comprising a plurality of fan blades; and a gearbox that receives an input from the first core shaft and outputs drive to the fan so as to drive the fan at a lower rotational speed than the first core shaft, wherein: the second turbine comprises at least one ceramic matrix composite component; and the mass of ceramic matrix composite in the second turbine is in the range of from 2% to 15% of the total mass of the second turbine.
