RISOptimization of LM2500 Gas Generator and Power Turbine Trim-Balance Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A procedure has been developed by the U.S. Navy to trim-balance, in-place, the gas generator and power turbine rotor of the LM2500 Marine Gas Turbine Engine. This paper presents the theoretical ...
Systematic Evaluation of U.S. Navy LM2500 Gas Turbine Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: From an operational availability stand point, the U.S. Navy is interested in the short term reliability of its ship based LM2500 gas turbine engines. That is the likelihood that an engine ...
Application of an Advanced Hybrid Rotordynamics Model to the Complete Structure of a Marine Gas Turbine Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Extensive fleet experience with the LM2500 marine gas turbine engine has identified it as an engine that exhibits wear-accelerating vibration effects. The critical speeds and associated mode ...
