STEADY AND TIME-DEPENDENT PROPELLER BLADE LOADING AND STRESS ANALYSIS
The unsteady lifting surface theory has been utilized in evaluating the blade loading distribution at all shaft frequencies and the corresponding hydrodynamic forces and moments at multiples of blade frequency (thrust, torque, bearing forces and bending moments) taking into account as realistically as possible the geometry of the propeller and the inflow field. Stresses are determined by means of beam theory and the finite element technique, although the latter should be considered as a first attempt.
