F414
Turbofan
The
F414-GE-400 turbofan engine with afterburner has been developed
by the American company General Electric on the basic of the F404.
It was specially developed for the new 2-engine F/A-18E/F
Super Hornet fighter jet for the United States Navy. The F414
is the successor of the F404 engine which is basically used on the
Hornet.
For the upgrade from F404 to the F414 the air inlets on the aircraft
have been enlarged because the F414 requires more airflow
(16% more airflow is sucked by the fan and 5% more by the first
3 rotor steps of the compressor).
Development
Originally the engine was designated as Growth II+ but changed in
to F414-GE-400 in 1991. It can deliver a thrust of 22,000 pounds
on sea level during ISO conditions. In 1992, GE was awarded with
a contract of the US Navy for the delivery of 13 engines for ground
tests and 21 engines for flight tests. The first F414 production
engines was delivered at the end of 1998 after completing the Engineering
and Manufacturing Development program. General Electric will deliver
the engine till 2010. The US Navy has already received more than
700 engines.
Features
The F141 delivers 22,000 pounds of thrust, which is 35% more power
than the F404. It is also more maintenance friendly and equipped
with a Full Authority Digital Electronic Control (FADEC) computer.
The F414-GE-100 has a 3-stage fan, 7-stage compressor, annular type
combustion chamber, 1-stage high pressure turbine, 1-stage low pressure
turbine, afterburner and a variable geometric nozzle.
