Abstract

The invention discloses a water surface aircraft water load full-aircraft power-free model pool test method. A test includes the following steps that firstly, full-aircraft power-free model test installation is performed; secondly, a full-aircraft power-free model pool test is performed, an electric cylinder (2) is started, an electromagnetic throwing device (3) is turned on, a full-aircraft power-free model (9) is thrown on the water surface at a constant vertical speed, the trailer speed, the water touching angle of the model, the overload and the pressure value are recorded at the same time, the water touching conditions of the model are recorded, and the loaded conditions of the model after the model touches the water are analyzed according to the model postures, the overloads and the pressure values of different test states. The water surface aircraft water load full-aircraft power-free model pool test method has the advantages of being practical, feasible, easy to operate, reliable in test result and wide in application range.

Description

technical field [0001] The invention specifically relates to a water load model test method for a water surface vehicle. Background technique [0002] At present, with the improvement of the range of use of water surface aircraft, the requirements for wave resistance are gradually increasing, thus putting forward higher requirements for the structural design and strength verification of water surface aircraft. In order to obtain a more accurate water load of the water surface vehicle for structural design and strength check, the scale model test of the water load pool of the water surface vehicle is mainly carried out at present. In the unpowered model pool test of the whole machine, the attitude, overload and pressure values ​​of the model after landing are mainly obtained through the test. At present, there is no practical test method for water-loaded full-machine non-powered model pool of water surface aircraft. Contents of the invention [0003] Purpose of the presen...
