Résumé | A multiple-variable linear regression direct solution model and a statistical model were developed for marine propeller design, optimization and prototype. Computing implementation for the direct solution model was made to create an integrated tool for the marine propeller development process. An error analysis for a simple case with only 4 independent variables was performed. This direct solution model was constructed to provide two functionalities: generation of a set of linear regression coefficients to establish a multiple-variable polynomial equation and interpolation of the multiple-variable data set that are generated by the polynomial equations. An application case was given using a set of data from a marine nozzle propeller series both to cover interpolation to produce curves and linear regression coefficients for interpolation, for both the direct solution model and the statistical model that was computed under a commercial software package. Though much higher than the statistical model, interpolation by the direct solution model showed an error of less than one-tenth of a percent for a group of nozzle propellers. The highly computing-efficient direct solution method showed its capability as a general-purpose linear regression tool which can be applied widely for optimal product prototyping and design. |
