This
display shows one of the earliest examples of a gas turbine engine
(1937). Designed in
England by Sir Frank Whittle, the engine utilizes
a centrifigal type compressor to drive
air
into a combustion chamber.
This air, combined with fuel (usually kerosene) continuously
burned,
and at a constant pressure, delivered to drive a turbine. All energy
was used to
propel the engine by direct reaction (less turbine
return), with the hot gases being
accelerated
through profiled
nozzles. This type of engine is commonly known as a Turbo-Jet.
The Whittle engine was licenced to GE in 1941. The GE engine (display
unit above) was
further
developed to provide 1,400 lbs of thrust (original
English version 1,200 lbs).
The
engine on display is one of 12 GE Whittle Engines still in existence
