Embodiment Construction

[0018] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0019] Combine Figure 1 to Figure 5 , The present invention includes a ship model 1, two large pillars 3, a hoist 2, a motor, a cable 4 and a measuring device 5. The pillars at both ends of the water (lake) (the distance between the two pillars is at least 300 meters) are equipped with hydraulic lifting and landing equipment, which can automatically adjust the height to ensure that the cable is always in a horizontal position. Synchronously control the speed of the two winches to meet the speed requirements of the ship model. The upper end of the measuring device is fixed at the center of the cable (1.5 meters from the cable), and the lower end is fixed at the center line of the ship model (0.5 meters from the ship model deck). The installation positions of the pillars at both ends of the lake are in the same straight line to ensure that the ship mo...

Abstract

The invention provides a cable-type intelligent airworthiness instrument device, which includes two height-adjustable pillars arranged on both sides of the water area, hoists respectively installed on the two pillars, a cable arranged between the two hoists, and a The lower end of the cable is provided with a support, the lower end of the support is provided with a ship model, and the support is provided with a measuring device. Since the cable-type intelligent airworthiness instrument device of the present invention carries out relevant hydrodynamic performance tests in real waters, compared with pool tests, it avoids the use of equipment such as pool aircraft and wave generators with high construction costs, and does not need to consider At the same time, the device has reasonable structure, easy operation, lower cost, more accurate experimental results and better test performance, which is of great significance to this type of test and has a very broad application prospect.

Description

Technical field [0001] The invention relates to a cable type intelligent seaworthiness instrument device, which is a new type of ship hydrodynamic performance measuring device suitable for lakes or reservoirs, which is a modification of the existing ship model towing pool measuring equipment. Background technique [0002] The ship model towing tank is a kind of equipment for hydrodynamic experiment, which can usually carry out fluid related tests such as ship model resistance test, self-propelled test, seakeeping test and propeller open water test. Limited to the test environment and scale of the tank, the scale effect and the Reynolds number need to be analyzed when the test data is processed. That is to say, it is impossible to meet the condition that all similarity criteria are equal to the actual ship during the ship model test. Similarity, leading to deviations in the estimation of actual ship performance from model test results. [0003] When carrying out hydrodynamic tests ...
