The linearized lifting surface theory has been applied to the evaluation of blade loadings and resultant hydrodynamic forces and moments (thrust, torque, bearing forces and bending moments) of counterrotating propeller systems with equal and unequal number of blades operating in uniform and nonuniform inflow fields, both units rotating with the same RPM. The mathematical model takes into account as realistically as possible the geometry of the propulsive device, the mutual interaction of propulsive device, the mutual interaction of both units and the three-dimensional spatially varying inflow field. A computer program has been developed adaptable to high-speed digital computers (CDC 6600-7600) for counterrotating propulsion systems of equal and unequal blade number in uniform inflow for comparison with experimental results if available.
