RISValidation of a Methodology to Assess the Flutter Limit Cycle Oscillation Amplitude of Low-Pressure Turbine Bladed Disks—Part II: Rotational Speed Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the operating conditions on the vibration amplitude trends of an isolated low-pressure turbine rotor is described. The study utilizes an analytical model correlating the aerodynamic and dry-friction work ...
Validation of a Methodology to Assess the Flutter Limit-Cycle Oscillation Amplitude of Low-Pressure Turbine Bladed Disks—Part I: Mach Number Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a methodology to estimate the vibration amplitude of fluttering low-pressure turbine (LPT) blades saturated due to friction effects. The study utilizes an analytical model that balances aerodynamic work ...
