Parametric Speed & Power
“How fast will it go?” The Orca3D Parametric Speed/Power Analysis module has two different prediction methods: the Savitsky method to predict the speed/power curve for chine hulls, and the Holtrop method to predict the speed/power for displacement hulls.
Most of the required input parameters are automatically computed from your model, although the user can input or override the values. Results are quickly generated and professionally formatted, and include checks to ensure the validity of the results. Any parameters that are outside of the ranges of the prediction method are flagged.
The results of the analysis are presented in easy-to-read reports, which include a summary of input data, checks of the parameters of your design versus the limits of the analysis method, and performance data versus speed. Plots of various parameters are also included, and the entire report may be printed or exported to Microsoft Excel or PDF.
