Description
Beamforming in aeroacoustics applications have undergone significant advances over the past decade, although successful source reconstructions depend on array geometry and the assumed source model. The application of phased-array algorithms to ground array measurements of a full-scale tactical jet engine yield equivalent source reconstructions for military and afterburner engine conditions. A deconvolution approach for the mapping of acoustic sources (DAMAS) is utilized to remove array effects seen in conventional beamforming and allows for improved interpretation of results.
