Embodiment Construction

[0014] Such as figure 1 The test procedure of the present invention is shown as follows:

[0015] a) Full machine power model test installation:

[0016] A sliding device consisting of the center of gravity strut 7, the trolley 5 and the heave rod 6 is used to install the full-machine unpowered model 1 on the airworthiness instrument 8 under the hydrodynamic high-speed test trailer system 12. The power model can move freely up and down and along the airworthiness instrument 8 within a certain range, and the movable connection point between the center of gravity strut 7 and the unpowered model 1 of the whole aircraft should be the center of gravity of the unpowered model 1 of the whole aircraft. Hinge connection, the unpowered model 1 of the whole machine can freely pitch and rotate around the position of the center of gravity, and the navigation piece 3 at the front end of the unpowered model 1 of the whole machine cooperates with the navigation rod 4 at the bottom of the hydrodyn...

Abstract

The invention relates to a full-aircraft power-free model basin test method for wave resistance of a water surface aircraft. The test step includes a) full-aircraft power model testing and installation: a full-aircraft power-free model (1) is installed on an airworthiness instrument (8) which is under a hydrodynamic force high-speed test trailer system (12) through a sliding device, the sliding device ensures that the full-aircraft power model (1) can move up and down in a certain range and freely move forwards and backwards along the airworthiness instrument (8), a gravity center support rod(7) is movably connected with the full-aircraft power-free model (1), a movable connection point of the gravity center support rod (7) and the full-aircraft power-free model (1) should take a gravitycenter position point of the full-aircraft power-free model (1), a hinge is adopted for a hinge joint, and the full-aircraft power-free model (1) can freely perform pitching rotation around the gravity center position point. The full-aircraft power-free model basin test method for wave resistance of a water surface aircraft has the advantages that the method is practical, feasible and simple to operate, a test result is reliable, and the range of application is wide.

Description

Technical field [0001] The invention specifically relates to a model test method for the anti-wave capability of a surface aircraft. Background technique [0002] The anti-wave ability of the surface aircraft directly affects the safety, comfort and range of use of the surface aircraft. In the preliminary design stage, to verify the anti-wave ability of the surface aircraft, the current main test is the pool scale model test of the anti-wave ability of the surface aircraft. The model test can be divided into a full-plane powered model pool test for the anti-wave capability of the surface vehicle and a full-plane unpowered model pool test for the anti-wave capability of the surface aircraft. Since the propeller rotating at high speed under large wave heights may be damaged by the impact of splashing in the test test of the full-powered model pool, it may even endanger the safety of the test personnel, so in the test of the full-powered model pool This limits the possibility of ch...
