Kurzfassung
In this paper, flow visualization of the blade vortices of four-bladed Mach-scaled rotor, as used in the ONERA-DLR ABC project (Active Blade Concept) in hover flight condition, were investigated experimentally by means of Background Oriented Schlieren method (BOS). For BOS setup, a high-speed camera with a resolution of 4 Mpx was used with pulsed LED-illumination in order to illuminate a reflective background. In addition, the influence of a flap mounted at the blade trailing edge, from 80% to 90% radius at different angles of deflections, on the density field of the blade tip vortex was studied. In order to compute the density field of the compressible vortex, tomographic reconstruction was applied to the BOS data.
