The Influence of Different Diving Angles on the Hydrodynamic Noise of Submarine Enclosures

Abstract

The hull is an important component of the submarine structure, and it is also one of the factors that affect the concealment of the submarine. By using the finite element method, a submarine model was established to analyze the hydrodynamic noise at the contact points between the front and rear of the hull and the hull under different diving angles. The results show that when the diving angle is about 10°, the hydrodynamic noise at the front and rear positions of the enclosure is relatively small. The research results provide a reference for ensuring the stealth operation conditions of submarines and have practical significance for improving the stealth of submarines.
