This Two Shaft Gas Turbine Unit investigates the behaviour during operation of a system with two independent turbines in a two-shaft arrangement and production of electrical power from mechanical power. One turbine (the high-pressure turbine) drives the compressor and the other turbine (the power turbine) supplies the effective power. Changes in power output in the power turbine have no influence on the compressor, which is able to keep running at optimum speed at the best efficiency point. The trainer includes the compressor, tubular combustion chamber and high-pressure turbine, fuel system, starter and ignition system, lubrication system, power turbine, generator, and measuring and control equipment with Touch LCD Display.

The gas turbine is started with the aid of a start-up fan. When the air enters the combustion chamber, only part of it is used for combustion. This air is decelerated with the aid of a turbulence generator such that the added fuel is able to burn with a stable flame. The greater portion of the air is used to cool the combustion chamber components, and is mixed into the combustion gases at the end of the combustion chamber. This reduces the gas temperature to the permissible inlet temperature of the high-pressure turbine. The gas flows out of the combustion chamber into the single-stage radial high-pressure turbine and discharges a portion of its energy to the turbine. This energy drives the compressor. In the power turbine, the gas discharges the remaining portion of its energy, which is converted into mechanical energy and drives a generator. The electrical energy generated is dissipated using electrical bulbs as load.

The unit has Touch LCD display for visualization of process and the measurements. The speed, temperatures, and pressures and the mass flow rates of the air and fuel are recorded and displayed using sensors. Typical characteristic variables are determined.

A PC data acquisition (EDSM-1000S) is also available (Optional).
