Calculation of Natural Vibration Frequencies and Transient Response of Partially Submerged, Supercavitating Marine Propellers.
Abstract
Procedures are presented whereby natural vibration and transient response analyses of partially submerged, supercavitating marine propellers may be calculated by means of a standard NASTRAN structural analysis program. The use of these procedures was demonstrated by analyses of an existing propeller, for which some experimental data were available. Results were comparable only in a limited way, but peak calculated dynamic stresses were of the same order of magnitude as those observed experimentally, and were apparently more then twice the magnitude of equivalent static stresses.
