[Ottawa] : Defence Research and Development Canada, c2013. vi, 26 p. : tables, graphs. Technical Memorandum ; 2013-178 "October 2013." Includes bibliographical references. The traditional method of specifying propeller geometry is to define a series of airfoil sections each of which is modified by local values of the chord length, pitch, skew angle and rake. Near the tip of the propeller, where the chord length reduces rapidly to zero, a blade defined in this way often has surface irregularities which make meshing for flow solvers difficult. Methods are described for smoothing the irregularities and saving the resulting propeller geometry in the IGES format which can be read by most flow solvers. gccst Technical reports Propellers Computational fluid dynamics Defence R&D Canada.
