Developed specifically for the Airbus A330 twinjet and introduced in 1994, the PW4000 100-inch fan engine has thrust capability from 64,500 to 70,000 pounds at take-off.
Offered as a complete propulsion system, the PW4000 100-inch fan engine features the industry’s lightest weight and most advanced nacelle. It also incorporates a number of service proven technologies in materials, aerodynamics and controls to enhance performance, reliability and durability. The engine was the first in aviation history to qualify for ETOPS (Extended-range Twin-engine Operations) prior to entering service. It is now approved for 180-minute ETOPS. And it meets all present and anticipated noise and exhaust emissions regulations. The engine is built to provide maximum value and its success is reflected by its service experience in the A330 market.
Pratt & Whitney is taking its successful PW4000 engine for the Airbus A330 to new heights with the introduction of the PW4170 Advantage70™. This program includes upgrades that enhance engine performance, save fuel, increase durability and reduce maintenance costs.
Advantage70 reduces fuel consumption over the baseline PW4168A engine by one percent, providing a direct savings of about $140,000 per aircraft per year. The fuel savings also means that each Advantage70-powered aircraft reduces its output of carbon by about 1.5 million pounds per year. Both the PW4168A and PW4170 meet regulatory noise level requirements with margin and produce the lowest total emissions compared with other engines powering the A330.
The PW4170 Advantage 70 is offered both as a new engine and as an upgrade to existing engines. The upgrade includes a package of technology enhancements which can be incorporated in your operators’ fleets during engine overhaul. The Advantage 70 upgrade is headed by a new high pressure compressor (HPC) ring case based on successful designs used on other members of the PW4000 family. The upgrade will lower fuel burn to provide best-in-class fuel efficiency and extend maintenance intervals.
New Pratt & Whitney PW4170 engines will enter service in 2009, starting with A330-200 freighters. As a leading OEM and MRO service provider, Pratt & Whitney is uniquely capable of developing ongoing improvements that reflect the company’s Green Engine program. Today, the PW4000 100-inch engine manual offer green alternatives for 76 percent of the listed repairs and replacements.
