UNDERWATER VEHICLE Russian patent published in 2019 - IPC F42B15/22 F42B17/00 

FIELD: hydraulic engineering.

SUBSTANCE: underwater apparatus relates to marine equipment and can be used to search for sea objects and physical action on them. Underwater vehicle consists of a head part accommodating an autonomous self-guidance system, contact and noncontact fuses, a control system with a recognition unit, hydroacoustic suppression and anti-torpedo protection. There are also small-sized drifting and self-propelled devices for hydroacoustic suppression and imitation, device for bringing enemy torpedoes out of action. In the middle part of the device there is an energy source and an engine. In tail part there is propulsor, drives of steering machines and outer tail unit with rudders. In the head part the electric blast block is rigidly fixed. It is made in the form of a thick-walled pipe. Its inner cavity is filled with ion-conducting liquid. One end of pipe is tightly sealed. Said sidewalls have two symmetrical holes arranged at said tight end. Working electrodes are hermetically sealed in them. Their discharge parts are located in internal cavity of pipe. Output of the first working electrode is connected to the capacitor bank terminal. Other terminal of the capacitor bank is connected to the electrode of the controlled discharger. Other electrode of which is connected to the second working electrode. Control electrode is connected to igniter pulses generator output. Its input is connected to contact and noncontact fuses. Cone-shaped plug is fitted on tube open end with cone inside said pipe. On the side surface of the pipe there is an inlet valve.

EFFECT: technical result is increase in safety during operation.
