Cluster large-scale three-dimensional flow field and hydrodynamic force synchronous measurement system and test method

Abstract

The invention relates to a cluster large-scale three-dimensional flow field and hydrodynamic force synchronous measurement system and a test method. The system comprises a fixed support, a six-dimensional force / moment balance, a circulating water tank, four high-speed cameras, a rear observation camera, an LED / laser high-intensity body light source, and the like. Key parameters reflecting the performance of an underwater vehicle, such as the energy utilization rate, the torque coefficient and the thrust coefficient of a bionic underwater vehicle in a cluster working mode, three-dimensional flow field characteristics in the cluster working mode, and motion characteristics, spanwise deformation, waveforms and the like of flapping wings of the vehicle in the experiment process can be measured at the same time, and the cluster formation is variable. The measurement system is simple in structure, high in reliability, high in measuring precision and flexible in measuring form. The test result is closer to the real situation of a bionic aircraft cluster operation mode, and effective reference and more accurate and more comprehensive data support can be provided for design of bionic aircraft engineering prototypes operating in a cluster mode.

Description

technical field [0001] The invention belongs to the field of underwater acoustic test platforms and test methods, and relates to a test method for a cluster large-scale three-dimensional flow field and hydrodynamic synchronous measurement system. Background technique [0002] 71% of the earth's surface area is seawater. The ocean not only contains abundant resources such as food, oil, and gas, but also plays an important role in military strategic space and transportation channels. The survival and development of all countries in the world are closely related to it. Therefore, At present, it is also known as the "golden age" for human beings to develop and use the ocean. Various underwater vehicles such as ships, submarines, submersibles, and underwater robots have become necessary tools for people to explore the ocean. As a bionic underwater unmanned intelligent mobile platform, the bionic unmanned underwater vehicle has broad application prospects and value in the fields o...

AI Technical Summary

Problems solved by technology

Therefore, even if the rest of the conditions are exactly the same, the flow field environment of the manta ray-like underwater vehicle in the swarm operation mode is obviously different from that of the vehicle in the single operation mode. Therefore, for the single operation mode The research on the bionic underwater vehicle does not provide enough reference for the research on the vehicle under the swarm operation mode

Similarly, separate studies on the three-dimensional flow field and the hydrodynamic performance of the aircraft cannot replace the simultaneous measurement of the three-dimensional flow field and hydrodynamics.
