PRATT & WHITNEY’S PUREPOWER ADVANTAGE

With 20 years of research and development, component rig testing on all major modules, extensive ground and flight testing of full-scale demonstrator engine complete and extensive ground and flight testing of its first two engine series well underway, the PurePower PW1000G engine with Geared Turbofan technology delivers game-changing reductions in fuel burn, environmental emissions, engine noise and operating costs.

In the PurePower PW1000G engine family, a state-of-theart gear system separates the engine fan from the low pressure compressor and turbine, allowing each of the modules to operate at their optimum speeds. This enables the fan to rotate slower and while the low pressure compressor and turbine operate at a high speed, increasing engine efficiency and delivering significantly lower fuel consumption, emissions and noise. This increased efficiency also translates to fewer engine stages and parts for lower weight and reduced maintenance costs.

In cooperation with parent company United Technologies Corporation (UTC), Pratt & Whitney sets aggressive EH&S goals that are continually met and exceeded. In 2007, UTC embarked on a four-year programme to reduce greenhouse gas emissions by 12 per cent, water consumption by 10 per cent, air emissions by 20 per cent and

- pared with 2006. These metrics are not normalised for business volumes that are growing, meaning that the per-product emissions will be dropping even more.

Pratt & Whitney’s greenhouse gas reduction target is equivalent to taking more than 16,000 cars off the road. In the first two years of the programme, Pratt & Whitney has reduced greenhouse gas emissions by 11 per cent, water usage
