Abstract: In this paper the response of a propeller to an unsteady, general velocity field (wake) is analysed. Besides the known parts of the wake, the direct - (homogeneous) and alternating current, a new part is introduced, the noise current which can be recorded by a simply statistical method. This new theory of wake shows that the frequencies of the fluid dynamic forces on the blades are not only integer multiplies of the number of blades and the revolutions of propeller but every frequency appears. Especially the first harmonic of the torque is generated by the noise current.
