ET 792 Gas Turbine* ET 794 Gas Turbine with Power
GUNT offers gas turbines for the following fields of application:
- ET 796 Single-shaft turbine: Jet engines
- ET 794 Two-shaft turbine: Power generation and drive systems
- ET 792 Two-shaft turbine: Combination of power generation and drive systems / jet engines
Experimental systems that clearly show the typical properties of gas turbines, easily understood by students.
The students become familiar with the typical properties of a gas turbine by manual start-up and operation of our two-shaft gas turbine. Safety devices ensure safe operation. Due to the operation of the two-shaft gas turbines with propane, they are protected against overspeed. The operation with gas as fuel also avoids dangerous hot starts occurring because of unburnt fuel remaining after a start-up abort.
Relevant values are measured by sensors, displayed and processed by a PC in many cases. This enables comprehension of the cyclic process and determination of power, fuel consumption and efficiency values etc.
The two-shaft turbines are equipped with silencers and can be operated in suitable and well ventilated laboratories. Cooling water and an exhaust gas system is required for operation.
A real jet engine in laboratory scale is used as the gas turbine for the trainer ET 796. The jet engine is a singleshaft engine with radial compressor, annular combustion chamber and axial turbine. As in reality the turbine is operated with kerosene. An electronic control unit (ECU) facilitates automated start-up and monitors turbine functions.
Because of typical noise emissions of jet engines, suitable noise reduction systems are necessary.

ET 795 Simulation of a Gas Turbine*
The GUNT simulator for gas turbines (ET 795) helps students become familiar with the typical behaviour of a gas turbine with minimal effort. The simulation also permits the safe investigation of behaviour in critical situations. Contrary to real systems, parameters such as state of inlet air or compressor pressure ratio are adjustable. Concept and operational behaviour are matched to both two-shaft turbines (ET 792, ET 794). Using the simulator is the ideal way to prepare students for experiments with the real systems.
