Abstract

Experimental design is a fairly old method of statistically analyzing an experimental prediction. This is used to replace a fairly old system as well, namely in the form of a trial and error method. Because with this method the response results approach from a study can be predicted statistically. In this study, we will calculate some torque values of a propeller on a displacement ship type. Where the ship's operational displacement ship runs on a Froude number below 0.25, for that the Wageningen B-series propeller type is very suitable for this ship. Furthermore, dimensional analysis is carried out with variables that affect propeller performance and uses multivariate combination calculations. The results of the study show the regression equation between the KQ values of the B-series propeller data and the regression formula with the equation Y = 0.9916x + 0.000835 with the value of R2 being 0.9931. so we try to apply an experimental design method to be validated with the polynomial results of the B-series propeller on blades 3 to 6, so that the statistical method of this experimental design is up-to-date in propulsion design calculations.

Abstract

Indonesia as an archipelago countries demand modern boats for marine security, resulting in a surge in the development of past patrol vessels. The investigation in this study focused on designs with and without a tunnel at the bottom to determine which design provided the least resistance. CFD offer realistic findings for comparing the problems encountered by two distinct kinds of fast patrol boats. The computation the use of no tunnel, the use of a tunnel on fast patrol boat reduced resistance by an average of 5.4%. According to the results of the CFD simulations, using a tunnel may greatly reduce the high pressure at the bottom in interactions with the flow of water. The utilization of using tunnel is a solution that may be employed more successfully for fast patrol boat operation
