An experimental facility for structural dynamics programs that uses an above-ground containment tank specifically designed to house bladed disks operating at design speed is described in this work. Key characteristics of the facility are discussed, and the configuration for a blade damping and mistuning study are presented. In particular, the development of an air-jet excitation system that can operate in different configurations to excite synchronous and nonsynchronous vibrations is detailed. Also, the measurement capabilities using a noncontact tip timing system as well as strain gauges are highlighted. Finally, results of data demonstrating the effectiveness of the facility for damping and mistuning studies are discussed.
