Gas turbine engine with compressor and turbine inside a hollow shaft

A gas turbine engine, which comprises:

• an outer engine case having a central channel, wherein a first end is an intake end while a second end is an exhaust end;
• a hollow revolving shaft which is supported interior to a circular surface of said outer engine case;
• an inner engine case which is supported inside said hollow revolving shaft, an intake nose protruding from said hollow revolving shaft being set at a front end of said inner engine case facing to an intake direction, an intake channel being formed between said intake nose and said outer engine case to direct air into said turbine engine, a rear portion of said inner engine case serving as can-shaped burner;
• a compressor, which is connected to said intake channel to compress outside air as high-pressure air and is composed of a plurality of said compressor rotor blades and a plurality of said compressor stator blades, said compressor rotor blades being set around said interior circular surface of said revolving shaft to be driven and rotated by said revolving shaft while said compressor stator blades being set on said inner engine case;
• a fuel supply device fastened inside said inner engine case, which is used to spray fuel to said burner to be mixed with said high-pressure air for combustion for producing a gas with high temperature and pressure;
• and
• a turbine composed of a plurality of turbine rotor blades and a plurality of turbine stator blades, wherein said turbine rotor blades are set around said interior circular surface of said revolving shaft to drive and to rotate said revolving shaft while said turbine stator blades are set on said inner engine case.
