Abstract
This extended abstract proposes the results and analysis of a an Airbus open rotor airframe model in an open test section using a large 5m x 6m aperture MEMS array with 12,000 microphones, that was moved to different positions to assess sound directivity. The full paper will include a detailed analysis of one Mach number, multiple RPMs and blade pitch angles, and three array positions. The results will be split into rotor noise and airframe noise. Only relative levels and frequencies will be shown in this publication. This is the second part of two related papers, focusing on advanced beamforming methods and the aeroacoustic analysis.
