Kurzfassung
In a major cooperative research program between 8 European partners, a 40%-geometrically scaled and highly instrumented model of the ECD (formerly MBB) BO 105 helicopter main rotor was tested in the open jetanechoic test section of the German-Dutch Wind Tunnel, DNW, in the Netherlands. A comprehensive set of simultanious accoustic and aerodynamic bladde surface pressure data as well as blade dynamic and performance data were measured for the standard rotor with rectangular blade tips. The primary objective of this experimental study was to generate an extensive airload and acoustic database and to examine the relation between the blade pressure characteristics and the acoustic radiation. Initial quantitativeinformation on blade-tipvortex trajector ies and blade positions during blade-vortex interactions was obtained. The blade pressure instrumentation, the experimental equipment used, the test procedures applied, and the scope of the test matrix conducted are briefly explained.
