Abstract:

An analysis of the rotational noise sound field of a rotorpropeller has been carried out. The resulting equations have been programmed on an IBM-360 computer. The program has been successfully checked out by comparison with existing theory. Also, a short parametric study has been carried out as part of the computer program evaluation.
