- Summary
- This Williams FJ44-3ATW turbofan engine powered the Virgin Atlantic Global Flyer. The lightweight, powerful, highly efficient jet engine enabled Steve Fossett to pilot the Global Flyer around the world nonstop, solo, without refueling in 2005. Fossett also set absolute distance and closed-course distance records with the aircraft in 2006.
- The engine is part of the successful FJ44 series of high-bypass turbofans begun in the early 1980s, and designed for the general aviation market. Its development enabled the class of business jets typified by the Cessna Citation. The first production version, the FJ44-1, received FAA certification in 1992. It features a 5 to 1 thrust-to-weight ratio, integrally bladed fans and compressors, and such low-cost turbofan technology as an uncooled, high-pressure turbine, an effusion-cooled combustor, and a high-work, two-stage, low-pressure turbine.
