UNDERWATER COMPLEX Russian patent published in 2018 - IPC F42B15/22 

FIELD: engines and pumps.

SUBSTANCE: underwater complex comprises a head part in which an autonomous self-guidance system is placed, an explosive charge, a contact and non-contact fuses, and a control system. In the middle part there are an energy source and an engine. The tail part accommodates a propeller, servo unit drives, and an external empennage with rudders. In the head part it is proposed to accommodate small-sized drifting and self-propelled means of hydro acoustic suppression and simulation, devices making torpedo or anti-torpedo of the enemy ineffective, devices for their storage, devices for start control, a control system of the underwater complex to be additionally equipped with a unit for recognition of operating detection means, hydro-acoustic suppression and anti-torpedo protection and calculation of the manoeuvre to overcome hydro-acoustic suppression and anti-torpedo protection. The small-sized drifting and self-propelled devices of hydro-acoustic suppression and simulation are designed for direct action on receiving hydro acoustic antennas of shipboard surveillance facilities and systems for detecting the anti-torpedo of the enemy, distortion of signals reflected from the underwater complex and creation of obstacles for determination of its true location, their distraction to false directions.

EFFECT: proposed underwater complex operates autonomously or under remote control, during the attack detected on a given route of the sea target it is capable to detect the operating observation means of the enemy, hydro-acoustic suppression and anti-torpedo protection means used by him, and to successfully overcome them, combine the manoeuvre and the use of internal counteraction means.
