LM2500™
LM2500™ / LM2500+™ / LM2500+G4™
The LM2500™ is a GE industrial gas turbine which derives from the CF6-6 aircraft engine. It has been maintained and repaired by MTU since 1981. Unlike the LM6000™ gas turbine, the LM2500™ is designed with a single-rotor gas turbine and an aero-dynamically coupled power turbine. The LM2500™ consists of a sixteen-stage compressor, a fully annular combustor, a two-stage high-pressure turbine and a high-efficiency power turbine. The LM2500™ gas turbine is the most popular aero-derivative in the 20 to 25 MW class.
The LM2500+™ and the LM2500+G4™ are uprated versions of the basic LM2500™ and offer 30.5 MW and 36.3 MW of power.
