Abstract
The paper gives a survey of experimental investigations of helicopter structural dynamics. It describes the features of the DLR ground vibration test facility with special emphasis on applications, experiences, and improvements in testing helicopter structures. This relates to realistic boundary conditions during testing, sensor instrumentation, dynamic excitation, and data reduction. An important topic is the correlation of experimental results with the mathematical model. Concepts for correlation, such as orthogonality check and modal assurance criterion, are discussed.
