Rolls-Royce Advances Toward UltraFan
UK engine maker Rolls-Royce is pushing ahead with advanced turbofan engine designs for future platforms, with greatly improved efficiency.
Titanium-aluminide low-pressure turbine blades and proposed cooling arrangements on Rolls-Royce’s proposed future UltraFan engine may owe much to the RB3025 powerplant unsuccessfully offered to power the Boeing 777X. For example, the RB3025 featured a “vortex amplifier” to simplify turbine-blade cooling with HPC air.
