A320neo’s first Pratt & Whitney test engine takes shape
26 October 2012
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.

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 environmental benefits.
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 optimized fan diameter and advanced core.
Overall the A320neo Family will 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. Additionally, the A320neo NOx emissions are 50% below CAEP/6, and this aircraft also has a considerably smaller noise footprint.
