Pratt andamp; Whitney and the Federal Aviation Administration (FAA) are each investing $25 million to develop an ultra-quiet engine fan and combustion technology that will reduce noise, emissions, and fuel consumption.The Geared Turbofan, which was introduced in 2016, was the beginning of making air travel more sustainable. The first engine in the family was produced for a single-aisle aircraft. As of today, the GTF engine family has help 54 operators save more than 500 million gallons of jet fuel and avoid 4.9 million metric tons of CO2 over 9.3 million flight hours.Pratt andamp; Whitney has partnered with the FAA's Continuous Lower Energy, Emissions and Noise (CLEEN III) initiative for more than 10 years."Our GTF engines already offer the highest efficiency and lowest CO2 emissions for single-aisle aircraft -- with a dramatically smaller noise footprint," said Tom Pelland, senior vice president of GTF engines at Pratt andamp; Whitney. "Today's FAA CLEEN III award will help us build on that success and aligns with our focus on driving sustainable solutions for our customers and the industry."
