Pratt & Whitney's Engines (2)
Pratt & Whitney's V2500 Engine
The V2500 engine is designed and manufactured by International Aero Engines, a global partnership of aerospace leaders including Pratt & Whitney, Rolls-Royce, Japanese Aero Engine Corporation and MTU Aero Engines.Â International Aero Engines brings advantages in technical excellence and manufacturing expertise, with a reputation of producing the engine of choice for the Airbus A320 family.
V2500 engines offer the most advanced technologies in the 22,000- to 33,000-pound thrust range with lowest overall emissions in its class.
The IAE V2500 SelectOneTM Â build standard will enter service in third quarter 2008.Â SelectOne will deliver one percent reduced fuel burn along with a corresponding reduction in emissions, and a 20 percentÂ time on-wing improvement while further enhancing the engineâ€™s durability.

Pratt & Whitney's GP7200 Engine
The Engine Alliance, a 50/50 joint venture between General Electric Aviation and Pratt & Whitney, was established in 1996 to develop, manufacture, sell and support a family of advanced technology engines for new high-capacity, long-range aircraft.Â The result is the GP7200, delivering 70,000 pounds of thrust for the Airbus A380 super wide-body.
The GP7000 is derived from two of the most successful wide-body engine programs in aviation history â€“ the PW4000 and GE90 families.Â The GP7200-powered Airbus A380 received type certifications from the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) in 2007.Â Â The joint certification followed 16 months of flight testing and paves the way for entry into service with Emirates in August 2008.

Pratt & Whitney PurePowerâ„˘ PW1000G Engine
Pratt & Whitneyâ€™s PurePower PW1000G engine is not just a concept or a promise for the futureâ€”it is reality. With 20 years of research and development, component rig testing on all major modules and ground and flight testing of a full-scale demonstrator engine, the PurePower PW1000G engine is already proving its ability to deliver game-changing reductions in:
- Fuel burn
- Environmental emissions
- Engine noise
- Operating costs
In the PurePower PW1000G engine, a state-of-the-art gear system allows the engineâ€™s fan to operate at a slower, optimum speed while freeing the low-pressure compressor and turbine to operate at their optimized higher 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 maintenance cost.
The PurePower PW1000G engineâ€™s fan-drive gear system is just one component of this next-generation engine. The PurePower PW1000G engine also incorporates advances in aerodynamics, lightweight materials and other major technology improvements in the high-pressure spool, low-pressure turbine, combustor, controls, engine health monitoring and more.
Pratt & Whitney has been actively testing all key components of the PurePower PW1000G engine family, with 16 technology rigs running around the world. In May 2008, Pratt & Whitneyâ€™s full-scale demonstrator engine completed a ground test program of more than 250 hours, with engine performance and noise levelsâ€”and fan-drive gear system reliabilityâ€”meeting or exceeding all pretest predictions.
The PurePower PW1000G demonstrator engine took to the skies for the first time in July 2008 on Pratt & Whitneyâ€™s 747SP flying testbed aircraft and will continue flight-testing through yearend on the 747 and then an Airbus A340-600 aircraft.Mitsubishi Aircraft Corporation has selected the PurePower PW1000G engine as the exclusive power for the next-generation Mitsubishi Regional Jet (MRJ).
The PurePower PW1000G engine has also been named as the sole propulsion system for the Bombardier CSeries mainline aircraft. Both applications of the PurePower PW1000G engine family are scheduled to enter service in 2013.With industry-leading technology, extensive rig testing and a full-scale demonstrator engine, Pratt & Whitneyâ€™s PurePower PW1000G engine is on track to redefine engine performance with double-digit reductions in fuel consumption, CO2 and NOx emissions, engine noise and operating costs. But being the first to deliver these game-changing advances isnâ€™t enoughâ€”Pratt & Whitney is committed to maintaining its leadership, with technology plans already in place to continually build on the PurePower PW1000G performance advantage beyond its 2013 service entry.
