Problems solved by technology

[0002] At present, with the significant increase in the use range of water surface aircraft, the requirements for wave resistance have gradually increased, and higher requirements have been put forward for the design of its water surface splash performance; in order to verify the design of water surface aircraft with excellent water surface splash performance, currently the main Aircraft splash pool scaled model test, the model test can be divided into water surface aircraft splash single-hull model pool test and water surface aircraft splash full machine dynamic model pool test; single-hull model pool test is used as hull line parameter selection and It is an important means of preliminary analysis of splash performance, and it plays an important reference role in the verification of splash performance of water surface aircraft; in the single-hull model pool test, the spray performance of the water surface aircraft model is studied by drawing the splash envelope, and by This is to preliminarily predict the splash performance of the water surface vehicle, and then to preliminarily verify the design of the splash performance of the water surface vehicle; at present, there is no practical test method for the water surface vehicle to spray a single hull model pool

Embodiment Construction

[0044] Test procedure of the present invention is as follows:

[0045] a) Installation of single hull model test:

[0046]The single-hull model 1 is suspended below the hydrodynamic high-speed test trailer system 17 through the unloading device 16, and the towing device 2 including the wire rope towing line 4 drags the single-hull model 1 to move together with the trailer. The unloading device 16 is composed of two pulleys. 19. The unloading box 21 and the steel wire rope suspension line 22 are composed. The two pulleys 19 are respectively installed on the bottom of the hydrodynamic high-speed test trailer system 17 through brackets. The steel wire rope suspension line 22 is wound on the two pulleys 19. The unloading box 21 is installed on one end of the steel wire rope suspension line 22. The other end of the wire rope suspension line 22 is connected with the single-hull model 1, and the towing device 2 is made up of a tugboat 23 and a wire rope tow line 4. One end of the to...
