An experimental study of the structure and acoustic field of a jet in a cross streamThe investigation reported is related to studies of the noise generated by a lifting jet in forward motion such as in the case of a V/STOL aircraft. The investigation involved experiments in a subsonic wind tunnel. The two-microphone cross-correlation method used for measuring the acoustic intensity provides data concerning the noise directly radiated from the source, practically free from any reflection effects. The theoretical basis of the two-microphone method is discussed along with the experimental apparatus, the characteristics of the flow inside the jet, and the features of the acoustic field.
