Embodiment Construction

[0030] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0031] A multifunctional bionic vehicle hydrodynamic test platform is built based on a circulating water tank, which includes two parts: autonomous cruise prototype test area A and prototype group tour and naca airfoil / pectoral fin / tail fin airfoil test area B. The floating bearing 15 installs the experimental objects to complete the hydrodynamic tests of different experimental models and different motion forms.

[0032] figure 1 It is a top view of the circulating water tank. The test section is bonded with transparent acrylic plates, and a tension-constraining frame is installed around it to make it have lateral pressure bearing capacity. The other parts of the main body of the cave are welded with 15mm thick PP plates. The power of the circulating water tank is provided by three aluminum impellers (8 blades) 10 with a diameter of 0.6m; the connecting pipe bet...

Abstract

The invention relates to a multifunctional bionic hydrodynamic test platform which comprises a circulating water tank, a carrying platform, an optical platform, an impeller and an autonomous cruise prototype mounting device. The hydrodynamic tests capable of being carried out comprise various aircraft group swimming hydrodynamic tests, hydrodynamic tests of starting-uniform motion-deceleration stop modes of autonomous cruise prototypes, and hydrodynamic tests of naca airfoils. Through the test platform, the energy conversion efficiency, the main shaft load, the torque coefficient and the thrust coefficient can be measured, vortex field analysis and track extraction of key positions of an experimental model can be carried out at the same time, and by means of the test platform, a mechanical hydrodynamic test of an airfoil can be completed; experimental verification can be provided for CFD numerical simulation and theoretical research of the hydrodynamic performance of the underwater vehicle, and reference and guidance can be provided for design of the underwater vehicle.

Description

technical field [0001] The invention belongs to the field of test platforms and relates to a multifunctional bionic hydrodynamic test platform. Background technique [0002] The 21st century is the century of the ocean, especially the century of the deep sea. The importance of the deep sea lies in the expansion of new space. In view of the fact that human beings are speeding up towards the deep sea, the strategic situation in the deep sea will largely determine the future international maritime political structure, and underwater vehicles, as an effective underwater vehicle, are playing an increasingly important role in the military and civilian fields. effect. How to effectively reduce the fluid resistance, how to effectively improve the propulsion efficiency of the vehicle, and how to improve the maneuverability and flexibility of the vehicle are important indicators for designing underwater vehicles. The hydrodynamic performance conclusions obtained only by numerical ca...
