TFE731
The 731 has been in production since 1972, and has powered 20 varieties of air-
craft, mostly business jets. Here we present the models with the least and
most thrust, though there is a range in between. It has a single-stage fan,
a 4-stage axial compressor, and a centrifugal high-pressure compressor.
