Abstract

The invention discloses a water surface aircraft water load model water-skiing test device and a water surface aircraft water load model water-skiing test method. The water surface aircraft water load model water-skiing test device comprises a test piece (1), a trailer (18), a central test bridge (19), a movable connection device, a head part protection device (5), a tail part protection device (6), a dragging device and test equipment, wherein the central test bridge (19) is installed at the bottom part of the trailer (18), and the movable connection device is composed of a sliding rail (20), a small pulley (4), a heaving rod (3) and a gravity center connection device (19). The water surface aircraft water load model water-skiing test device has the advantages of simple structure and convenient operation, and the water surface aircraft water load model water-skiing test method has the advantages of being practical, feasible, simple in operation, reliable in testing results, and wide in application range.

Description

technical field [0001] The invention specifically relates to a hydroplaning test device and a test method of a water-surface aircraft water load model, which provide design input for the structural design and strength check of the water-surface aircraft. Background technique [0002] At present, with the improvement of the range of use of water surface vehicles, the requirements for wave resistance are gradually increasing, which puts forward higher requirements for the structural design and strength check of water surface vehicles. In order to obtain a more accurate hydroplaning load of the water surface vehicle for structural design and strength check, it is mainly through the hydroplaning test of the water surface vehicle water load model pool, and the attitude, overload and pressure values ​​of the model can be obtained from the test. At present, there is no practical hydroplaning test method for the water load model of the water surface vehicle. Contents of the invent...
