Pratt & Whitney introduced the JT8D to commercial aviation in 1964 with the inaugural flight of Boeing's 727-100 aircraft. Many variants of the JT8D family have been produced, covering the thrust range from 14,000 to 17,400 pounds and powering 727, 737, and DC-9 aircraft. More than 11,800 JT8D standard engines have been produced, accumulating over 600 million hours of service operation.
The JT8D-200 series covers the 18,500- to 21,700-pound thrust range and is the exclusive power for the popular MD-80 series aircraft. Since starting service in 1980, more than 2,900 JT8D-200 engines have been produced.
To ensure the JT8D-200 stays current with environmental regulations, Pratt & Whitney has developed a new low-emissions combustion system, or E-Kit, that is FAR 25-certified. The E-Kit reduces JT8D-200 NOx emissions by 25 percent, unburned hydrocarbons by 99 percent and smoke by 52 percent. The E-Kit exceeds all ICAO standards for new production engines and qualifies for the Swiss Class 5 (cleanest) emissions category.
P&W and Aviation Fleet Solutions (AFS) have jointly developed a noise reduction kit for JT8D-200 powered MD-80 aircraft. The kit enables operators to comply with Chapter 4 noise standards while maintaining thrust and performance levels, and was FAA/EASA certified in 2006. The kit includes an improved fan inlet liner, a 16-lobe mixer, a muffler, and a tabbed nozzle and can be installed on-wing.
Flight-testing of a JT8D-200-powered 707 in late 2001 demonstrated the -200's substantial performance improvements and feasibility to complete J-STARS and AWACS mission profiles.
