Pratt & Whitney has invested billions of dollars in the Geared Turbofan
We are excited to be a part of Embraer s E-Jets E2 program providing the industry-leading benefits of the Geared Turbofan
engine, including significant reductions in noise, emissions and fuel burn, said Greg Gernhardt, president, Pratt & Whitney Commercial Engines.
Rolls plans to have a geared turbofan
flying by 2025 in what is being called its UltraFan, which will house numerous advanced components and technologies, and yield the 25% fuel efficiency improvement over its existing baseline engine model, the Trent 700.
What differentiates a geared turbofan
from a regular turbofan is that the large fan at the front of the engine operates at a lower speed than the turbine that drives it.
FARNBOROUGH AIR SHOW -- Pratt & Whitney's Geared Turbofan
engine will power Lufthansa's new Bombardier CSeries aircraft.
The model will feature a next-generation Pratt & Whitney engine called the Geared Turbofan
and advanced aerodynamic design, which will substantially reduce fuel consumption and lower operating costs, according to the Japanese manufacturer.
Pratt sees GTF service entry possible in 2012 Pratt & Whitney expects to be able to bring its proposed Geared Turbofan
single-aisle engine to market by 2012, with a 12% improvement in fuel burn compared with today's narrowbody engines, a 20%-25% reduction in noise (dBs) and a 70% reduction in NOx emissions versus CAEP 2, President Steven Finger said yesterday at the company's media day in Hartford, Conn.
GOTEBORG, Sweden -- The PW1100G engine is a part of Pratt & Whitney's Next Generation Product Family of engines which contain geared turbofan
We are excited to be a part of Embraer's E-Jets E2 program providing the industry-leading benefits of the Geared Turbofan
engine, including significant reductions in noise, emissions and fuel burn," said Greg Gernhardt, president, Pratt & Whitney Commercial Engines.
Bombardier said the incident did not involve the PW1524 model of P&W's new geared turbofan
motor that powers the CSeries jet.
Volvo Aero said it will join Pratt & Whitney "to demonstrate new technology" for Pratt's Geared Turbofan
Technology demonstrator program.
The PW1000G engine uses patented Geared Turbofan
technology where a state-of-the-art gear system allows the engine's fan to operate at a different speed than the low-pressure compressor and turbine.
GKN Aerospace has signed a GBP multi-million, long term agreement (LTA) with Kawasaki Heavy Industries (KHI) to supply titanium rotating parts for the PW1100G-JM and PW1400G-JM, Geared Turbofan
The Geared TurboFan
engine will deliver double-digit improvements in fuel efficiency, environmental emissions and noise.
Pratt continues to develop its geared turbofan
technology targeted for that market.
