Abstract

The invention belongs to the field of hydrodynamic tests of a water surface aircraft model, and discloses a hydrodynamic derivative testing system for a water surface aircraft hull. The hydrodynamic derivative testing system for the water surface aircraft hull comprises a six-degree-of-freedom platform, a six-component balance, a towing vehicle and a water surface aircraft, wherein the six-degree-of-freedom platform comprises an upper platform, a lower platform and six electric cylinders, two parallel measuring bridges are arranged on the towing vehicle, the lower surface of the six-componentbalance is connected with the upper surface of the water surface aircraft hall, the upper surface of the six-component balance is connected with the upper platform of the six-degree-of-freedom platform, and the lower platform of the six-degree-of-freedom platform is connected with the two measuring bridges of the towing vehicle. The invention provides a hydrodynamic derivative testing method withthe high rigidity testing system, good model posture adjustment precision and high test result precision.

Description

technical field [0001] The invention belongs to the field of hydrodynamic test of a surface aircraft model, and in particular relates to a test system and method for the hydrodynamic derivative of a surface aircraft hull, which are used for testing the hydrodynamic derivative of a surface aircraft hull. Background technique [0002] The measurement of the hydrodynamic derivative of the hull of the surface vehicle includes the measurement of force and moment, so a six-component force balance is used. The previous hydrodynamic model test method uses a small-sized six-component force balance to fix the model, forming a form similar to a point-fixed surface, resulting in The stiffness of the test system is poor, the results are inaccurate, and the attitude of the model is also adjusted manually, so the adjustment accuracy is difficult to control, especially for the compound state with roll and pitch attitudes, it is difficult to adjust. Contents of the invention [0003] In vi...
