Сonstruction features:
10-speed centrifugal compressor;
tubular combustion chamber (2 flame tubes);
3-stage turbine;
built-in coaxial gearbox (gear ratio 1: 4.66).

DO49R is the basis of low-power gas turbine thermal power plants (GTES-2.5 and others) (from 2.5 to 15 MW and above) for generating electric and thermal energy in simple and cogeneration cycles.
Advantages:
high quality of generated energy and good dynamics during transients (including through the use of a single-shaft circuit);
high fuel efficiency, reduction in the cost of generating electric and thermal energy;
the possibility of block replacement of a gas turbine plants (GTD), gearbox, other components and elements in operation;
increased resistance to sulfur corrosion and marine climate;
the ability to work on various types of fuel: gaseous (natural gas, associated petroleum gas) and liquid (kerosene, diesel fuel).
