Is the Rolls-Royce UltraFan geared?
The UltraFan features a geared architecture, with a variable pitch fan system, while the Trent engines use a traditional fixed pitch fan system. The geared architecture of the UltraFan allows the engine to operate more efficiently at slower fan speeds, reducing noise and improving fuel efficiency. A step-change in efficiency And that means greater efficiency and sustainability. UltraFan is 25% more efficient than the first-generation Trent and offers 40% less NOx and 35% less noise and almost zero nvPM particulates at cruise.
Does the Boeing 777 use Rolls-Royce engines?
The first generation of Boeing 777 models, the -200, -200ER, and -300 have since been known collectively as the Boeing 777 Classics. These three early 777 variants had three engine options ranging from 77,200 to 98,000 lbf (343 to 436 kN): General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800. The GE90 engine held the record as the world’s most powerful jet engine for nearly 15 years, clocking in at 127,900 pounds of sustained thrust in 2002. This was on a par with the solid-fuel rockets used by NASA in the 1960s space exploration. Over the years, the GE90 also became a symbol of innovation as well as power.GE90 is used in Boeing’s 777-200, 777-200LR, 777-300, 777-300ER and 777 Freighter aircrafts and 70 different operators prefer GE90 engines worldwide.
