Abstract
The invention relates to an underwater resistance towing test method for a submersible vehicle model. The underwater resistance towing test method comprises the steps of: step 1, installing a submersible vehicle model; step 2, calibrating and fine-tuning the submersible vehicle model; step 3, installing and debugging a test instrument; step 4, carrying out a resistance test and recording data; step 5, and processing the data. The underwater resistance towing test method can eliminate influences of double swords and a connection method on the test result to the greatest extent, and ensure the precision and reliability of the test. The underwater model resistance test method is provided by the invention, and the reliability and precision of the test method are improved.
Description
technical field [0001] The invention relates to the field of hydrodynamic tests, in particular to an underwater resistance drag test method of a submersible model. Background technique [0002] The existing resistance test methods are all designed for conventional surface ships, and the resistance drag test of underwater submersibles is much more complicated than that of surface ships, whether it is test equipment or design and installation. method. [0003] Compared with conventional surface ships, underwater submersibles have unique military advantages. First of all, they have good concealment and can use the cover of the water layer for concealed activities. The base goes deep into the enemy's sea area to fight independently. It can launch missiles and deploy torpedoes underwater. With the development of my country's national defense construction and marine economy, the demand for high-performance underwater submersibles is increasingly urgent. [0004] Pool drag test is...
