Abstract

Measurements of the noise emitted by the V2500 engines of the Airbus A320 research aircraft ATRA of DLR have been performed under static conditions in a ground test and in a flight test. The ground test measurements were performed with a linear microphone array laid out on the ground in parallel with the engine axis. The fly-over measurements were performed using a large multi-arm spiral array. Frequency spectra from different directions calculated from the ground test data and Doppler corrected frequency spectra from the flight test data show good agreement in the broadband levels and even in the levels of the engine tones.
