The engine was first tested on the Pratt & Whitney Boeing 747SP on July 11, 2008 through mid-August 2008, totaling 12 flights and 43.5 flight hours. [14] It then flew starting October 14, 2008 on an Airbus A340-600 in Toulouse on the number two pylon. [15] Testing of the CSeries bound PW1524G model began in October 2010. [16]
YF119-PW-100L: Prototype engine for the YF-22; rated 30,000 lbf thrust class. YF119-PW-100N: Prototype engine for the YF-23; rated 30,000 lbf thrust class. F119-PW-100: Production engine for the F-22A with larger fan and increased bypass ratio (BPR) rated for 35,000 lbf thrust class. YF119-PW-611: Prototype engine for the X-35.
If the fan and fan case are removed the engine may be shipped using a 747 Freighter. [22] The -94B for the -200ER was retrofitted with some of the first FAA-approved 3D-printed components. [23] In 2011, its list price was US$27.5 million, and it had an in-flight shutdown rate (IFSD) of one per million engine flight-hours. [3]
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades.
The P-409 engine was also proposed for use in the EA-6B ADVCAP, [10] but that program was canceled after three prototypes were built and flown. The P-409 would have been available as a new engine or as an upgrade kit for P-408 engines, but was never ordered in significant quantities. [11] [12] PW1212 J52-P-409 re-designated PW1216
The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...
In December 1980, Pratt & Whitney changed to a new naming system for its engines and the JT10D became the PW2037. The PW2000 is a dual-spool, axial air flow, annular combustion, high bypass turbofan with a dual-channel full authority digital engine control system. It was certified in 1984 as the first civilian FADEC-controlled aviation engine.
The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model. The engine was designed with a higher priority on reliability than performance.
