About the F100 Turbofan:





The Pratt & Whitney F100 is a two-spool afterburning turbofan engine. The F100 has been selected by the U.S. Air Force (USAF), Navy, Air Force Reserve, Air National Guard (ANG) and 22 foreign nations for the Boeing F-15 Eagle/F-15E Strike Eagle and the Lockheed Martin F-16 Fighting Falcon multi-role fighters. F100 engines power 99% of all USAF F-15 aircraft and 62% of the world's inventory of F-16 fighters. The F100 has a record of dependability, performance and safety. To date, more than 7,200 F100 engines have been produced and more than 24 million flight hours accumulated.



The latest model in the F100 Series, the F100-PW-229 (introduced in 1992), is an improved high-thrust improvement of the older F100-PW-220 (introduced in 1986). The F100-PW-229 incorporates proven technological innovations and generates more than 29,000 pounds of thrust with afterburner. The modular maintenance concept, coupled with a state-of-the art FADEC (Full Authority Digital Engine Control) system with improved, real-time engine monitoring and fault isolation capability, promotes the highest level of operational readiness.

The newest engine in the Pratt & Whitney 229-Series, the F100-PW-229 Engine Enhancement Package (EEP) - launched in 2004 - achieves the objective of increasing the engine depot inspection interval from 4,300 to 6,000 Total Accumulated Cycles (TAC), effectively extending the typical depot interval from 7 to 10 years and, at the same time, providing a 30% engine life-cycle cost reduction. Furthermore, the F100-PW-229 engine is the only fighter engine funded and qualified by the U.S. Air Force to the 6,000-cycle capability.



The F100-PW-229 EEP includes advanced hot section technology developed for the F119-PW-100 turbofan used on the F-22 Raptor and the F135 engine used on the F-35 Lightning II. The EEP configuration was incorporated into all production F100-PW-229 engines in 2009 and has been specifically designed to be easily installed in all existing pre-2009 F100-PW-229 engines.

Another variant of the F100, the F100-PW-220U, powers Northrop Grumman's X-47B flight test aircraft for the U.S. Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program. The F100-PW-220U provides up to 16,000 pounds of thrust and is designed for operation in a maritime environment such as on aircraft carriers.
