Pratt & Whitney’s JT8D-219 is the latest version of the
popular JT8D engine family. More
than 350 operators use JT8Ds to power approximately 12 percent
of the world’s
commercial airline fleet. The -200 series covers the 18,500- to
21,700-pound thrust range,
and it is the exclusive power plant for the MD-80 aircraft and
the Super 27 re-engining
program for the B727 aircraft. Since starting revenue service in
1980, more than 2,900
JT8D-200 engines have been produced, logging more than 110
million hours of flight. Pratt & Whitney
and Seven Q Seven have entered into a joint venture (JV) to
re-engine B707-model aircraft with
JT8D-219 engines for commercial and military applications. The
JV is under contract to Northrop
Grumman to begin re-engining the United States Air Force (USAF)
E-8C Joint STARS aircraft.
The JT8D-219 is a dual-spool, low-bypass-ratio turbofan with a
service-proven design. The -219
builds on the JT8D family’s excellent reputation for high
reliability and low maintenance cost. For
B707s with JT3D engines, re-engining with JT8D-219 offers
excellent performance and cost-saving
opportunities, including higher thrust and a 19% reduction in
fuel burn (typical mission) for attractive
gains in payload and range. The JT8D-219 also reduces perceived
noise by approximately 50%, while
reducing smoke, carbon monoxide and unburned hydrocarbons by 85%
or more.
The latest version of the JT8D-219 incorporates reliability
improvements that will further extend
time on-wing and reduce maintenance costs. It also features the
capability for higher power
extraction to meet the increased power requirements for
state-of-the-art military avionics and
surveillance equipment as well as for commercial onboard
electrical needs.
