Description

The TGT1.5K system was developed to allow the study of a two-shaft gas turbine. The fresh air is sucked in by the compressor and sent to the combustion chamber where it will be mixed with the fuel (gas) and ignited. The expansion will drive the generator turbine which is linked to the compressor. The flow of hot gas air is then sent to the working turbine which will generate the mechanical power and drive the electric brake. The assembly is instrumented in order to be able to calculate all the efficiencies and powers of the system. The start of the turbine is automated and assisted by a fan.The machine is completely secured with emergency monitoring and shutdown elements.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on wheels gives it a very high robustness as well as a great flexibility of integration in your premises. The manufacture of this equipment meets the European Machinery Directive

The bench is installed on an aluminium profile structure equipped with four braked-directional castors.
It includes an electrical box with a power disconnector and a 30mA RCD.
