Airbus’ A320neo programme has moved a step closer to the real aircraft with the
assembly of the first engine-to-test – the Pratt & Whitney (P&W) PurePower PW1100G-JM engine. This engine is due to begin testing very soon at P&W’s facilities in Florida, USA.
The PurePower engine uses an advanced gear system for the fan. This configuration
was validated in Toulouse on Airbus’ A340 flying-testbed aircraft in 2008 during P&W’s ‘geared-turbofan’ conceptual phase. The gear allows the engine’s fan to operate at a different speed than the low-pressure compressor and turbine. The combination of the gear system and an all-new advanced core is a solution which delivers fuel efficiency and
Paul Adams, Senior Vice President, Operations & Engineering, Pratt & Whitney said: “Pratt & Whitney is proud that its PurePower PW1100G-JM will be the first engine to enter service on the Airbus A320neo. We are confident the Geared Turbofan provides
the best value proposition for the future, and that our new engine for the A320neo family is well positioned to support Airbus in this market segment.”
Klaus Roewe, Airbus’ Senior Vice President A320neo Family said: “The Pratt & Whitney PurePower engine is an integral part of the Airbus A320neo family of aircraft.” He added: “Commencing the test programme of the new engine is an important milestone on our common journey and we are looking forward to the test results and also to the continued integration work of the engine into the aircraft.”
The A320neo gives operators a choice of two new engines – the PurePower PW1100G-JM
from Pratt & Whitney and CFM International’s LEAP-1A turbofan, each with a fully optimised fan diameter and advanced core.
Overall the A320neo Family is designed to deliver fuel savings of 15% and an additional
flight distance of 500 nautical miles (950 kilometres), or the ability to carry two tonnes more payload at a given range. For the environment, Airbus says the A320neo’s fuel savings translate into some 3,600 tonnes less CO2 per aircraft per year (the equivalent of taking 1,000 mid-size cars off the roads). Additionally, the A320neo NOx emissions are
50% below CAEP/6, and this aircraft also has a considerably smaller noise footprint.
The A320neo is on track to enter service from 2015.
