The noise emission of a V2500 engine during ground operation was investigated with the A320 research aircraft ATRA of the German aerospace center DLR. Acoustic measurements with a microphone array parallel to the engine shaft axis were performed with the engines running at different speeds between idle and maximum continuous thrust. The main measurements took place in a noise-protection hangar, because optical measurents with laser devices were performed in parallel. In order to assess the… Expand
