Text

Two-shaft turbine for highest efficiency and power
in the 20-40 MW class



PGT25+G5

The PGT25+G5 is the latest generation of our LM2500/PGT25 family

The PGT25+G5 is the latest generation of our LM2500/PGT25 family—including over 2,500 engines with nearly 100 million combined operating hours in applications around the world.



Benefits

  • Maximized power: 38.3 MW (+10% vs. G4) with 41% efficiency at full power
  • Mean Time Between Maintenance: 25,000 hour inspection, 50,000 hour overhaul
  • Can reach 36,000 and 72,000 hours MTBM when de-rated to G4 power
  • NOx emissions: 25 ppm at full power, reaching 15 ppm when de-rated to G4

Features

  • High-pressure compressor inherited from G4 with redesign for enhanced durability
  • Combustor leverages latest DLE technologies, and capabilities from the LM6000
  • Gas generator leveraging latest GE Aviation materials, coatings, and cooling technology
  • High-speed power turbine: upgraded materials, aerodynamic and thermal modifications.
