Abstract

The invention relates to a full-aircraft power-free model water-tank testing apparatus for testing a surge handling capacity of a water-surface aircraft. The testing apparatus comprises a high-speed test trailer system body (21), a full-aircraft power-free model (22), a gravity center connecting rod (1), a jigger (2), a guide wheel assembly, a deep sinking rod (3), a middle unloading device, a tail unloading device, an airworthiness instrument (14), a front traction device, and a rear traction device. The bottom of the deep sinking rod (3) is connected with the full-aircraft power-free model (22) by the gravity center connecting rod (1); and a deep rod through hole is formed in the jigger (2). With the testing apparatus, the pitching and deep sinking motions of a model can be realized and the flight attitude and angle changes as well as the changing immersion depth situation of the model during the testing process can be measured. With the middle unloading device and the tail unloading device, the influence on the flight process of the aircraft by the aeroplane propeller movement can be simulated truly, so that the authenticity of testing data are improved.

Description

technical field [0001] The invention specifically relates to the field of hydrodynamic tests of amphibious aircraft, seaplanes, etc., and in particular to a model test device for the anti-wave capability of water surface aircraft. Background technique [0002] The anti-wave capability of the surface aircraft directly affects the safety, comfort and scope of use of the surface aircraft. In order to verify the anti-wave ability of the surface aircraft in the preliminary design stage, the water tank scale model test of the anti-wave ability of the surface aircraft is mainly used. The model test can be divided into the full-machine powered model pool test of the anti-wave capability of the surface aircraft and the full-machine non-powered model pool test of the anti-wave ability of the surface aircraft. Because the propeller rotating at a high speed under a large wave height may be damaged by the impact of splashing in the test of the full-machine driving model pool test, it may...
