Pratt & Whitney's PW4000 94-inch-fan
The 94-inch-fan PW4000 engine is the first model in Pratt & Whitney's high-thrust family for large aircraft. It covers a range of 52,000 to 62,000 pounds of thrust and has five major aircraft applications. Most of the airlines operating the engine depend on it to fly Extended-range Twin-engine Operations (ETOPS) routes with Boeing 767s or Airbus A310s/A300s. The PW4000 is approved for 180-minute ETOPS, which gives airlines the ability to fly across oceans or barren terrain three hours from the nearest suitable airport. In fact, the 94-inch PW4000 has completed more than 2 million ETOPS flights with 38 airlines. Advanced, service-proven technologies, such as single-crystal superalloy materials and Full-Authority Digital Electronic Control (FADEC), contribute to the engine's superior fuel economy and reliability. Its attractiveness is further enhanced by excellent performance retention, turbine durability and good value. Pratt & Whitney reached a major milestone for the PW4000 engine program in November 2002 when the U.S. Federal Aviation Administration certified a new high compressor case design for the 94-inch fan PW4000 engine. The design is based on the PW4000-112 and has begun production incorporation and is now also available to airlines for incorporation at overhaul. The new design improves blade tip clearance control over the service interval and has demonstrated excellent high power operability. The new HPC features also have improved overall fuel efficiency, fuel performance retention and EGT margin. Engine Characteristics Fan tip diameter: 94 inches Length, flange to flange: 132.7 inches Takeoff thrust: 52000 - 62000 pounds Flat rated temperature: 86 or 92 degrees F Bypass ratio: 4.8-to-1 to 5-to-1 Overall pressure ratio: 27.5 -32.3 Fan pressure ratio: 1.65-1.80
