Multifunctional bionic hydrodynamic test platform

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...

AI Technical Summary

Problems solved by technology

The hydrodynamic performance conclusions obtained only by numerical calculation or commercial software fluent have limitations and cannot guide the design of aircraft well, so this also promotes the development of hydrodynamic test platforms

[0003] Existing hydrodynamic test platforms are mostly aimed at conventional ships, and test platforms suitable for bionic aircraft, naca airfoils, pectoral / tail fin airfoils and other hydrodynamic explorations are yet to be developed. development, especially the lack of multifunctional hydrodynamic test platforms integrating multiple tests
