Prediction of propulsion of ships with screw propellers are based on the data of self-propulsion tests of ship models and open water propeller tests. The complication of realization of open water tests for the majority of waterjet types makes difficulties for the definition of propeller-hull interaction coefficients and of initial data for impeller design. The overcoming of these difficulties expects the use of the calculating methods or the developing of special experimental devices. The methods of self-propulsion tests are considered. Also the stands and facilities for excluding the influence of ship hull on impeller action are described, the different principles of analysis of test results are discussed. Main reasons of errors are evaluated and the methods of their excluding are proposed. The peculiarities of the model tests of waterjets with different constructive schemes are discussed. The practice of model tests and the method of their analysis in Russian laboratories are substantiated.
