Abstract

The invention relates to the technical field of ships, and provides a self-hidden bubble curtain protection system and an underwater vehicle. The self-hidden bubble curtain protection system comprises a steam supply device, a vacuumizing device and a plurality of nozzles, the steam supply device is connected with the multiple nozzles through steam paths, the multiple nozzles are used for being arranged on a protection body and spraying bubbles to the outside of the protection body, the vacuumizing device is used for being communicated with a water inlet in the protection body, and the multiple nozzles are arranged on the protection body. And therefore, negative pressure can be formed at the water inlet relative to the outside of the protection body. When the self-hidden bubble curtain protection system is applied to the underwater vehicle, the bubble curtain can be provided to absorb shock waves when the underwater vehicle is attacked by external weapons such as torpedoes; and the problems of secondary exposure and wake flow aggravation of the underwater vehicle body can be relieved, and the survivability of the underwater vehicle is improved.

Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a self-concealed bubble curtain protection system and a submersible. Background technique

[0002] Bubble curtain technology has been applied to practical projects such as underwater blasting protection due to its excellent protection ability. Bubble curtain technology can greatly reduce the impact of various underwater shock waves by generating a bubble isolation zone around the protection body, and play a role in protecting the protection body.

[0003] In the field of ship technology, researchers consider applying bubble curtain technology to submersibles, by setting a bubble generation system on the submersible to generate a bubble curtain. However, there are still a large number of engineering problems in the use of bubble curtain protection technology on submarines. For example, there are secondary exposure and wake aggravation, etc., when the main body is easily exposed wh...
