Description
Technical Field
The invention relates to a device and a method suitable for a hull hydrodynamic model test of a water jet propulsion ship, and belongs to the technical field of ship design.
Background
The hull hydrodynamic model test mainly comprises two types: one is a resistance test, which tests the resistance acting on the ship body at different navigational speeds and provides resistance parameters for navigational speed forecast; the other type is a Plane Motion Mechanism (PMM) test, which tests hydrodynamic force acting on a ship body in a specified motion state of oblique navigation, pure transverse oscillation, pure yawing oscillation and the like and provides hydrodynamic derivative for establishing a manipulation motion equation. For conventional boat types, the above two types of model tests have matured and form relevant test protocols. However, no reasonable universally accepted method has been developed for waterjet propelled marine vessels. At present, two methods are mainly adopted, one method is to seal a flow inlet on a ship body during a test without considering the influence of a water jet propulsion system on the hydrodynamic force of the ship body, but the method is obviously not suitable because the flow inlet and the flow rate greatly influence the hydrodynamic force acting on the ship body. The other method is to directly carry out resistance test and plane motion mechanism test after installing the water jet propulsion system. However, the hydrodynamic force obtained by the test method contains the thrust generated by the water jet propulsion system with a large magnitude, and the thrust has great influence on the hydrodynamic force acting on the ship body. The hydrodynamic derivative of the ship body maneuvering motion obtained based on the test method is not clear in physical significance, and the influence of certain local modification on the overall maneuverability of the ship design is not convenient to explore.
