Abstract

New developments in power electronics (such as the linear motor) may be of great advantage for future economic aerodynamic testing. After a comprehensive review of economical aspects of present wind tunnel technologies, the experimental verification of the hybrid wind tunnel concept will be presented. A scale law is derived to extrapolate the experimental results of the model-HWT to a facility size for simulating full scale Re-numbers. Finally, methods will be discussed by which the flow constancy during the running time may be improved.
