Abstract
A high-speed BOS (Background Oriented Schlieren) system has been installed at the Airbus A320 aircraft engine in the sound-attenuating hangar during the DLR project SAMURAI. The density gradient structures of the free jet flow of a V2527 jet engine at maximum continuous thrust (MCT) have been recorded in a large domain with high temporal resolution. The measurements disclose the qualitative temporal evolution of these structures as well as an estimate of the time-averaged density. A cross-correlation analysis between the BOS measurements and a far-field microphone signal was used to examine the density structures connected to the noise generating processes.
