Description

technical field [0001] The invention relates to a surface resistance testing device, in particular to an underwater multifunctional bionic surface drag reduction testing device. Background technique [0002] At present, the marine strategy is the national strategy that each country focuses on. There are many resources in the ocean, which are also of great benefit to the development of the national economy. Therefore, improving the development of marine security is also an indispensable strategy for every country. Regarding marine security and economy, navigation tools in the ocean, such as ships, fish, and warships, also play a huge role in the economic development of the ocean and national defense security. Nowadays, the demand for energy is increasing, and the energy reserves are also decreasing. Therefore, how to make ships and ships in the ocean sail more efficiently has become an urgent problem to be solved. It is necessary to improve energy utilization efficiency and i...
