TGFAC Турбина газовая осевого потока/ Реактивный двигатель, управляемые с компьютером (ПК)

The main element of the "TGFAC" unit is the gas turbine, which consists of:

• Axial compressor, supplied by atmospheric air that will be compressed afterwards.
• Annular combustion chamber, where fuel is added to the compressed air and that mixture is burnt. The combustion gases increase their temperature and velocity.
• Expansion axial turbine. The obtained combustion gases flow to the axial turbine, where they transfer part of their energy to the vanes. Since the compressor and the turbine are coupled on the same shaft, when the system is self-sustained, part of the energy of the combustion gases is used to move the compressor. Both the turbine and the compressor are made up of discs with vanes that rotate (rotor) and stationary ones (stator). The difference is that the compressor transforms kinetic energy into pressure while the turbine performs the opposite work. The gas expands when being expelled, its temperature drops and is accelerated. It is expanded till environmental pressure at the outlet of the nozzle and reaches great speed, generating the thrust.

The gas turbine works as open cycle process, air is taken from the environment and expelled to the environment.

Besides, the unit includes a series of additional installations:

• Starting system: it is completely automatic, it is done with the aid of an electric starter motor that, coupled to the shaft of the compressor, generates the rotation of the shaft. There is a spark plug for the ignition.
• Fuel supply system: the fuel (kerosene/paraffin) passes through a filter and is supplied by a pump to the combustion chamber.
• Lubrication of the turbine: it is carried out with the oil mixed with the fuel (with a proportion of 5 % of special turbine oil).

The "TGFAC" unit includes the sensors required to measure all the important parameters of the process: pressure, temperature, air flow and fuel flow, speed and force (movable table with force sensor to measure thrust).

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
