According to Pratt Whitney Using hollow titanium shroudless fan blades the PW4000 provides high efficiency and low noise along with superb resistance to foreign object damage. The PW4000 112-inch engine an ultra-high-thrust model covering the 74000 to 90000 pound-thrust class is the reliability experience and Extended-range Twin-engine Operations ETOPS leader for the 777 aircraft providing the best customer value. A United Airlines 777 PW4000 engine failed shortly after takeoff from Denver on Feb.

The airline has already grounded all of its Boeing 777-200s fitted with PW4000 engines in preparation for the AD. It almost landed. The Federal Aviation Administration FAA has said that it wants to see parts of the PW4000 engine strengthened before flying again.

Today the Pratt Whitne. Pratt Whitney PW4000 adalah keluarga mesin pesawat high-bypass turbofan bersertifikat dengan daya dorong mulai dari 52000 sampai 99040 lbf 230-441 kN. It was designed specifically for the A330 and today has 230 engines in service.

The Pratt and Whitney PW4000 engine family spans from 50000lbs to a planned 100000lbs thrust and comes from the Pratt and Whitney division of United Technologies and is assembled in Hartford Connecticut. Investigations into both incidents are being conducted by local civil aviation authorities. The PW4000 94-inch fan engine is the first model in the PW4000 family of high-thrust engines.

This version was FAA-certified in 1993 and entered service in 1994. Figure 2 illustrates the schematic diagram configuration of the PW4000 engine and the station numbering for each. Developed specifically for the Airbus A330 twinjet and introduced in 1994 the PW4000 100-inch fan engine has thrust capability from 64500 to 70000 pounds at take-off.

Following an incident on a United flight in February all Boeing 777s flying with the Pratt Whitney engines have been grounded for inspections. PW4000 engine 11 ENGINE CYCLE AND STATION NUMBERING Some certain specific points along the engine axial profile are identified by station number to provide ease of reference for items such as component locations. Matt Griffin Matt is a London-based writer and reporter for International Flight Network who has been involved in aviation from a very young age.

Combined with other safety factors the agency has determined that carriers have to conduct a thermal acoustic image TAI inspection of the large titanium blades at the front of the engine. It was first run in April 1984 and received its FAA certification in July 1986. Blades that are found to have cracks will need to be removed and replaced.

The 100-inch fan diameter PW4000 powers the Airbus A330 aircraft -200 and -300. The Pratt Whitney PW4000 is a family of high-bypass turbofan aircraft engines and was the successor to the JT9D. What is an Aero-derivative Engine.

It provides thrust from 64000 pounds to 70000 pounds. The engine was the first in aviation history to qualify for Extended-range Twin-engine Operations ETOPS prior to entering service. Why you might ask.

Pratt Whitney celebrates 30 years of PW4000-94 revenue service marking the delivery of its first PW4000-94 engines in June 1987. It is now approved for 180-minute ETOPS. It covers a range of 52000 to 62000 pounds of thrust and has five major aircraft applications.

The FAAs directive requires a thermal acoustic image TIA inspection for cracks in first-stage LPC blades. Dibangun sebagai penerus mesin seri JT9D telah menemukan aplikasi yang jauh lebih luas daripada pendahulunya.
