Pratt & Whitney JT8D
The Pratt & Whitney JT8D jet engine
was introduced by Pratt & Whitney
in February 1964
with the inaugural flight of the Boeing's 727
. Today, the eight models that comprise the JT8D standard engine family cover the thrust range from 14,000 to 17,400 pounds and power 727, 737
, and DC-9
aircraft. More than 11,800 JT8D engines have been produced.
A modern derivative, the -200 series, covers the 18,500- to 21,700-pound thrust range and powers the McDonnell Douglas MD-80. Since starting service in 1980, more than 2,900 -200 series engines have been produced.
The JT8D also powers some military 707s and JointSTARS and AWACS surveillance aircraft, and has been adapted to a variety of other uses.
