[0002] At present, for the water surface aircraft and land-based aircraft wave water surface tow pool model water landing test, the model is basically moved by the trailer and the model is released at an appropriate position. In this way, the model and the water surface move at the same time, and it is still impossible to obtain and control the wave and water surface. For the encounter position of the model, in order to obtain the maximum water impact load, repeated tests can only be performed many times, and then statistical analysis is used; at the same time, the test method does not have the function of accurately determining the water impact moment, and the sinking speed at the water impact moment is confident. low level

Description
technical field [0001] The invention relates to the field of water impact test, in particular to a wave water surface model water impact test device and method. Background technique [0002] At present, for water surface aircraft and land-based aircraft wave water surface towing pool model landing tests, the basic method is that the trailer moves with the model, and the model is released at an appropriate position. In this way, the model and the water surface move at the same time, and it is still impossible to obtain and control the wave The encounter position of the model, in order to obtain the maximum water landing load, can only use repeated tests for many times, and then use statistical methods to analyze; at the same time, the test method does not have the function of accurately determining the water landing time, and the sinking speed at the water landing time is confident. low level. SUMMARY OF THE INVENTION [0003] The present application proposes a wave water ...
