The availability of newly constructed low-noise aeroacoustic facilities such as the German-Dutch-Windtunnel and the French CERPA 19 Anechoic Open Jet Windtunnel provides excellent experimental possibilities for conducting high-quality acoustic source-studies on aerospace vehicle noise generators. This paper discusses recent and ongoing model-scale research on basic phenomena and applied problems pertaining to the generation and radiation of propeller and helicopter rotor noise. The importance and potential of aeroacoustic wind tunnel experiments in special facilities is stressed, and illustrated mostly by examples of DFVLR and US-Army/DFVLR research projects. Emphasis is also put on the fruitful interrelationship of model-, wind-tunnel and full-scale flight testing.
