Jet engines are gas turbines which generate thrust. Jet engines are used on aircraft for
propulsion due to their low weight and high performance. The SMT-HT-50 trainer investigates
the behaviour during operation of a jet engine. SMT-HT-50 includes the following
components: jet engine (with compressor, annular combustion chamber, turbine, and
propelling nozzle), fuel system, starter and ignition system, and measurement and control
equipment. The gas turbine works as an open cyclic process, with the ambient air being drawn
out and fed back in. In the jet engine, the ambient air drawn in is first brought to a higher
pressure in the single-stage radial compressor. In the downstream combustion chamber, fuel
is added to the compressed air and the resulting mixture is ignited. The temperature and flow
velocity of the gas increase. The gas flows out of the combustion chamber into the singlestage axial turbine and discharges a portion of its energy to the turbine. This turbine drives
the compressor. In the propelling nozzle, the partially expanded and cooled gas expands to
ambient atmospheric pressure and the gas accelerates to almost the speed of sound. The
high-speed gas outflow generates the thrust. In order to reduce the outlet temperature, the
exhaust gas stream is mixed with the ambient air in a mixing pipe.
