SUMMARY
The gas turbine engine has five major sections: inlet,
compressor, combustion, turbine, and exhaust. Engine terminology
includes directional references, engine stations, and model
designations.
Gas turbine engine construction is not limited to one type of
compressor. The compressor may be either centrifugal or axial or a
combination of the two. Compressors are made in single or multiple
stage assemblies.
Three basic types of combustion chambers are in use: the
annular, can, or a combination of the two called canannular or
cannular.
