Modal testing of 9 m CX-100 turbine blades

Abstract

Several modal tests were conducted on several CX-100 9-meter wind turbine blades (manufactured by TPI Composites Inc.) as part of an evaluation to identify their structural dynamic characteristics. Experiments were made with the blades using different boundary conditions including free-free and clamped. The data for the different tests was processed and compared for the different configurations. This paper presents the results of those studies to provide a database for future use. © The Society for Experimental Mechanics, Inc. 2012.
