Abstract

Self-propelled ship model test is conducted the indispensable ship model pilot project corresponds to the speed of the propeller thrust and torque can be obtained through the self-propulsion test , analysis of various propulsion efficiency component , in order to determine the ship , machine , paddle three meet overall performance. Self-propulsion test single oars or sculls ship model has become the routine testing of the ship model pool project , but the more number of propeller ship model testing has not been carried out in the country , with the development of modern shipbuilding technology , of three paddle or four paddle Experimental study of the ship model began to become a hot research topic . The content of this thesis is to establish in the laboratory four - oar boat model test on the basis of the test process : first propeller open water tests of open water performance of propeller model of self-propulsion test of the four - oar ship model testing ; then resistance test ship models , resistance curve ; self-propulsion test by test , analysis of different test combinations of self-propulsion test propeller position to promote efficiency , to choose the best combination of propeller position . The thesis is divided into three parts , each part is as follows : 1 propeller open water tests . - B5-105 test with a propeller propeller and one MAU series propeller open water tests , the propeller open water performance curve and calculated using the calculation method based on the lift plane theory , the propeller open water performance , and compare the results of calculation and experimental and propeller design pattern of results , two examples of the calculation results with the experimental and map the results are in good agreement fully proved the accuracy of the calculation program . Ship model resistance test . Ship model resistance test is a routine test , the performance analysis of the self-propelled essential step in order to get the resistance curve . Ship model self-propulsion test . First using orthogonal test method 18 representative test model , due to the conflict of the mounting position of the paddle mold , there are three groups of test can not be carried out , and the remaining 15 trials in the boat pool . The results obtained in the propulsive efficiency analysis, to get the best combination of propeller position . The purpose of this experiment is to fill the blank of domestic self-propulsion test paddle boat mold accumulated valuable trial experience , for future research reference .
