Rotor Lifetime Extension (LTE)

PSM’s Rotor Lifetime Extension program can extend the lifetime of your rotor. With advancements in computing power, material properties, fracture mechanic methodologies, and inspection techniques,  it is possible to assess the potential to run gas turbine rotors beyond their original published limits. Optional rotor modifications can be applied called LifeMods and Robust Back End Upgrade (7F) are designed to extend rotor lifetime in known life limiting locations.
