The PurePower PW1700G and PW1900G engines are the exclusive power plants for the E-Jets E2. The geared architecture, combined with the all-new, advanced PurePower engine core enables the engines to deliver significant economic and environmental benefits, without compromise.
With E2 orders, it translates to about 1,200 engines for Pratt & Whitney. Substantiating this at the cabin mock-up event of E-Jets E2 in Singapore, the Vice President, Sales (APAC) Pratt & Whitney, Mary Ellan Jones said the Geared Turbo Fan (GTF) on the E2 is not just about gears. “It is enabling technology with huge environmental benefits, low fuel burn and reduction in noise.” There is reduction of 3,600 tonnes in carbon emissions per aircraft per year which is equivalent to planting about a million trees.
Giving example of noise reduction, she said that studies had showed that there was 71 per cent reduction in noise contour over the Hong Kong International airport. The noise is limited to the airport area and not affecting the community close to the airport.
The GTF engines, she mentioned, had been selected by five aircraft and the PurePower PW1700G and PW1900G engines which were selected by Embraer in 2012, will see E190-E2 entry into service in 2018, the E195-E2 in 2019 and the E175-E2 in 2020. The joint development phase with Embraer is underway and the first engine test of PW1900G will be in the second quarter of 2015 and engine certification in first quarter of 2016. The programme is on schedule.
Utilising the PW1000G engine family test programme experience, the PW1700G and PW1900G engines benefit from millions of hours of experience at EIS, providing dependable engines for the E-Jets E2.
15 to 16 Per Cent Leaner
The PurePower 1000 engine family improves fuel burn up to 16 per cent versus today’s best engines from regional jets to mainline single-aisle aircraft. That alone could save airlines nearly $14,00,000 per aircraft per year.
50 Per Cent Cleaner
Pratt & Whitney’s TALON X combustor slashes polluting emissions. The PW1000G engine family will surpass the most stringent standards (CAEP/6) by 50 per cent for nitrous oxide.
75 Per Cent Quieter
The PurePower PW1000G engine family reduces aircraft noise footprints by 50 to 75 per cent. Operating 15 to 20 dB below today’s most stringent (ICAO stage 4) standard brings a competitive advantage for operators, savings from lower noise fees, increased operations within curfews and optimised flight tracks through preferred runway access.
$2 million Lighter
That is how much operators could save per aircraft per year, versus today’s best airplanes, states Pratt & Whitney. The PW1000G engine family addresses the whole picture – fuel, emissions, noise and maintenance, to give the operator the lowest possible cash operating cost.
