F100
Turbofan
The F100
turbofan engine with afterburner was specially developed for the
US Air Force F-15 and F-16 fighter jets. Currently there are the
3 versions: F100-PW-200, F100-PW-220, F100-PW-229 from Pratt &
Whitney. All engines are 2-shaft engines with afterburner and variable
geometric nozzle. The newest type, the F100-PW-229 is used on the
Advanced F-16's Block 52.
The engine is a low-bypass
twin-spool (low and high pressure compressor) turbofan engine with
afterburner.
Features
The P&W F100 engine has a full length annular type fan, a 3-stage
low pressure compressor (with the fan driven by the LPT on the N1-axis),
a 10-stage high pressure compressor (driven by the HPT on the N2-axis),
an annular type combustion chamber, 2-stage low pressure turbine,
2-stage high pressure turbine, afterburner and a variable geometric
nozzle.
To avoid compressor stall there has been build in a solution. The
startengine is coupled to the HPC. Thanks to this the N2-axis will
rotate first. Later, the LPC will also rotate thanks to aerodynamic
coupling.
The Royal Netherlands Air Force uses the F100-PW-200 (photo 1).
