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.

Artemis Digital Displacement technology could be used to control the bypass fan for greater efficiency. Extra fans or even propellors could be added to all planes for more efficiency and reliability.
The technology should be required for all cars just like converters on the exhaust or seat belts. It can cut fuel use in vehicles to half since a smaller engine can be used for the same acceleration. With the INNAS NOAX engine the moving parts of the engine could be reduced to one. Someone can invent a way to pump fluid with a fast Capstone turbine and use the ARTEMIS motors on the wheels. Much cheaper than electric motors of the same power. ..HG..
