Projects

Project of retrofitting of the stand ET4 for research of non-stationary processes at GTU operation at extreme partial load modes.

In order to simulate the operation of the system “Stage - Diffuser” at the GTU idle mode it is necessary to supply additional power to the last stage. For this purpose the stand ET4 can be retrofitted with an additional model stage or an electric motor with a frequency regulator can be used as a source of additional power.

Stand ET4 retrofitted with electric motor.
