Propeller blade is replaced by source and doublet distribution referring to acceleration potential; in linearized approach used, distributions are situated at helicoidal surface described by propeller; doublet distribution leads to lifting surface problem, whereas source distribution corresponds to thickness problem for usually nonsymmetrical blade; results were obtained for pressure variations and for noise level in certain points due to each of 2 cases.
