METHOD OF INCREASING PROPULSIVE PROPERTIES OF UNDERWATER VEHICLE WHEN CREATING THRUST Russian patent published in 2024 - IPC B63B1/32 B63H11/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to full-formed underwater vehicles. Method of increasing the propulsive properties of the underwater vehicle when creating thrust consists in the fact that at least four cruise propulsors are installed on the hull of the underwater vehicle along the circumference of the stern to provide thrust along the axis of the underwater vehicle, maneuvering in the vertical and horizontal plane and installing the same number of stabilizers between the cruise propulsors. Propulsor is also installed in the aft end of the underwater vehicle from cylindrical recesses with inlet and outlet flat slotted channels, in which by means of auxiliary rotor propellers, respectively, tangential suction and supply of water to the surface of the housing are performed to reduce the resistance of water to movement of the housing. Outlet flat slotted channels are arranged in front of each stabilizer in the after part of underwater vehicle in the area where the hull diameter begins to decrease.

EFFECT: higher reliability, survivability of underwater vehicle and reduced probability of navigation accidents.
