Ground vibration testing (GVT) of aircraft is typically performed very late in. the development process. The main purpose of the test is to obtain experimental vibration data of the whole aircraft structure for validating and improving its structural dynamic models. Among other things, these models are used to predict the flutter behavior and carefully plan the safety-critical in-flight tests. Due to the limited availability of the aircraft for a GVT and the fact that multiple configurations need to be tested, an extreme time pressure exists to get the test results. This article discusses recent hardware and software technology advancements for performing GVT that are able to realize an important testing and analysis lime reduction without compromising the accuracy of the results.
