Estimation of Turbine Blade Natural Frequencies from Casing Pressure and Vibration Measurements

Estimation of Turbine Blade Natural Frequencies from Casing Pressure and Vibration Measurements

Non-contact measurement of gas turbine rotor blade vibration is a non-trivial task, with no method available which achieves this aim without some significant draw-backs. This paper presents a truly non-contact method to estimate rotor blade natural frequencies from casing vibration measurements at a...
