The simple-cycle, two-shaft LM500 offers an aerodynamically coupled power turbine, and is similar in design to GE’s proven LM2500 gas turbine. The LM500 is basically a CF34 engine without its fan and is very similar in materials. The LM500 incorporates a variable stator compressor driven by an air-cooled, two-stage turbine. The LM500 has the latest in proven design technology and corrosion-resistant materials to provide a mature design with maximum reliability and component life.
This gas turbine is suited for marine applications requiring light weight and fuel economy. The LM500 is ideal for patrol boats and hydrofoils, as well as a military generator set.
The 6,130-shp LM500 is adapted from the CF34 engine and has the highest fuel efficiency of any gas turbine in its output class.
