JExTRA – Jet Noise Experiments at AT-TRA

Kurzfassung

This report by Max Nussbaumer is the result of his summer internship from 1. July 2015 to 11. September 2015 at DLR engine acoustics in Berlin. Under the supervision of Henri Siller, he performed acoustic measurements with a microphone array in the JExTRA jet facility. The jet facility was provided by Robert Meyer, the anechoic set-up of the microphone array has been conceived and constructed by Alessandro Bassetti with the support of Wolfram Hage and Larisa Hritsevskyy, who together with Stefan Funke supported the experiments. Stefan Funke also consulted Max Nussbaumer during the data reduction. Karsten Liesner supported the operation of the jet facility and adapted the control software.
