Research Institution
Characterizing turbine engine rotor vibratory characteristics is becoming increasingly complex with the introduction of advance technologies, such as integrally bladed rotors (IBR), low aspect ratio airfoils, 3-D aerodynamic computational fluid dynamics (CFD) design blades, and advance materials. The analysis and measurement techniques used to evaluate the vibratory characteristics has also advanced, but often times resulting in increased information from dissimilar sources. The objective of this research is to develop improved rotor vibratory characterization through integration of all the available data sources, including Finite Element Models, non-contact stress measurement systems (NSMS) and strain gages. In Phase I, feasibility of the integration was demonstrated in different planning, testing, and analysis phases of the vibratory characterization test process on a laboratory rotating rig. Phase II will extend the concepts demonstrated in Phase I to application on highly instrumented, advanced technology turbine engines.
