The UltraFan® from Rolls-Royce promises to redefine the world of jet engines by delivering significant weight, noise, and fuel burn reductions with a 25% increase in efficiency over the first-generation Trent engine.
Rated at 84,000-lb. thrust and with a 140-in.-dia. composite fan, UltraFan also features a new geared architecture (with a power gearbox introduced between the fan and intermediate pressure compressor) to ensure that the fan, compressors, and turbines all continue to run at their optimum speed.
Rolls-Royce is testing the UltraFan, with ground tests scheduled to begin in 2021.
