The operation of a jet turbine engine involves all of the listed parts above. A tube with a
compressor and a turbine share a common shaft with a burner and a propelling nozzle, and fuel is
pumped through the inlet nozzle and through the turbine and ignited, then is released through the
exhaust nozzle. The turbine uses a high exhaust velocity to produce thrust for the engine.
Inlet Nozzle – Allows air to enter the turbine
Fuel injector – Injects fuel into the air entering the turbine
Compressor – compresses the fuel injected air into the turbine
Turbine – Pushes the fuel injected air through the engine into the combustor to ignite
Exhaust Nozzle – allows the exhaust to leave the turbine and causes a high exhaust
velocity which produces thrus
The best indicators for thrust besides rpm and fuel flow are Noss exit pressure, Turbine exit
pressure, turbine inlet pressure, compressor exit pressure, and compressor inlet pressure. Graphs
below prove this point.
As you can see these 5 measurements are all good indicators of thrust. As well as being good
indicators of thrust the graphs are very similar which gives support to the fact that these measurements
are good indicators of thrust on the turbine engine.
