A THEORY FOR THE VIBRATORY FORCES ON A FLAT PLATE ARISING FROM INTERMITTENT PROPELLER BLADE CAVITATION

The force induced on the plate by the expansion and contraction of the cavitation on each blade of an M-blade propeller is found without determining the detailed distribution of induced pressures, much of which makes no contribution to the force. The results show large values at the higher multiples of blade harmonics.
