Abstract

This report describes the conduction and analysis of an aeroacoustic wind tunnel campaign at the Aeroacoustic wind tunnel facility in Braunschweig (AWB). The test has been conducted from November 2020 to January 2021 by the experimental aeroacoustics group of the Technical Acoustics division under the lead of Michael PottPollenske in cooperation with Airbus Defence and Space. The cause of the project is the investigation of an over-the-wing engine installation of a rectangular nozzle. The general objective is the quantification of jet noise shielding due to the presence of the wing. The test setup consists of a high aspect ratio rectangular engine (AR=13.3) which is installed over a plate. The test parameters can be narrowed down to 5 parameters: engine operation, flight speed, length, height, and connection between engine and plate (none or wooden filler). By the positioning of the height, three different physical setups are tested in order to achieve a noise reduction or shielding effect of the jet: the axisymmetric rectangular nozzle, the jet-surface interaction, as well as the (theoretically) undisturbed shear layer. The positioning of the length allows to test the shielding of parts of the jet near field and (for 1 setting) the full potential core.
