... lifting surface method for the calculation of blade forces on both rotors and stators. The lifting surface method includes features that are important for the modeling of complex propulsors. Temporally-varying forces are computed for a blade-row rotating in a spatially-varying flow field. The spatially...

... A new method for the optimisation and design of Contra-Rotating Propellers (CRP) is presented in this paper. It is based on a Genetic Algorithm (GA) applied to a Vortex Lattice Method, used to compute the optimum spanwise distribution of circulation. chord length and thickness. Computation...

.... A Navier-Stokes equations solver has been selected to compute the flow past the afterbody/ducted propulsor configuration. The rotor is modeled as an actuator disk with finite thickness. Computational results are shown to compare favorably with published data for fine sterns and open propellers.Illustrative...

... Cavitation extents and cavitation-induced fluctuating pressures on an adjacent body are computed and compared with experimental results for propellers operating in a nonuniform flow Three five-bladed propellers with varying degrees of skew are selected for calculations. An unsteady lifting...

... are generally supported by experimental data. A new term in the analysis arises from a radial onset flow component and an example illustrates its importance in design. Sufficient information for manufacture is obtained for computer run times from 400 to 1200 seconds on the Burroughs 7700 high-speed computer...
