TDA design has the following peculiar features: nozzle sets have variable blades furnished with turning mechanisms, thus providing wider operating range. Gas inlet in the horizontal plane through the symmetrical volute chamber is tangential to the rotor axis, while gas outlet is along the axis. Rotor discs are mounted on the shaft between supports of plain bearings. Horizontally positioned axis in the reduction gearing. Welded valve blocks in the control system.
