Abstract

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. The ABC rotor blades include a trailing edge flap of 15% chord mounted from 80% to 90% blade radius. In this project, the influence of several flap angles of deflections on the density field of the blade tip vortices was studied. In order to compute the density field of the compressible vortex, a tomographic reconstruction algorithm was applied to the BOS data.
