Jet engine maker Rolls-Royce revealed details of its two next generation engine designs based on its Trent engine family, which are under advanced stage of development, offering better fuel efficiency, reliability and environmental performance. The engines could be ready within 10 years.
The first design called Advance, will offer at least 20 per cent better fuel burn and CO2 emissions than the first generation of Trent engine and could be ready from the end of this decade.
The second, UltraFan™, a geared design with a variable pitch fan system, is based on technology that could be ready for service from 2025 and will offer at least 25 per cent improvement in fuel burn and emissions against the same baseline.
The designs will feature architecture and technology improvements that include:
- A new engine core architecture - to deliver maximum fuel burn efficiency and low emissions.
- A CTi Fan System - carbon/titanium fan blades and a composite casing that reduce weight by up to 1,500lb per aircraft, the equivalent of carrying seven more passengers at no cost.
- * Advanced ceramic matrix composites - heat resistant components that operate more effectively in high turbine temperatures.
- A geared design, called UltraFan™, which will deliver efficient power for high-thrust, high-bypass ratio engines of the future.
