Experiments

  • Study of a Joule-Brayton cycle.
  • Study on a reduced scale of a plant for the production of electrical energy by a gas turbine.
  • Study of the starting procedure of a gas turbine.
  • Measurement of the air flow input as a function of the speed of the turbo-charger.
  • Pressure and temperature in the combustion chamber as a function of the speed of the turbo-charger.
  • Calculation of the specific consumption as a function of the speed of the turbo-charger.
  • Calculation of the output power as a function of the speed of the power turbine.
  • Determination of the power output with different input parameters.
  • Safety systems in the operation of a gas turbine.

The unit consists of a wheeled frame made of steel, of a panel with mimic diagram carrying the measurement instruments and of a base where the main components are installed, that is the combustion chamber, the turbo charger assembly, the power turbine and the alternator. The exhaust gases produced by the combustion of the compressed air/gas mixture are made to expand first through the turbine of the turbo charger assembly in order to supply the energy necessary to compress the air and then through the power turbine coupled to the alternator through a toothed belt. The electric energy generated by the alternator is dissipated on a resistive load.

The unit is supplied with manuals which describe all parts of the trainer, the installation and utilization procedures, as well as many exercises with the relative results.

The unit is available in:
Computerized version unit which allows thanks to the electronic transducers and suitable software, to display and/or print on personal computer the tables of results and diagrams of the experiments.
