FIELD: shipbuilding; marine propulsors for high-speed, low-speed and positioning submarines. SUBSTANCE: proposed propulsion complex includes propeller, steering nozzle in form of annular wing with its convex side directed inside and device for securing it on underwater vehicle hull or its engine nacelle with narrowing taper aft extremity. Flow-through circular passage of propulsor is formed by narrowing part of hull on inner side and by convex part of nozzle on outer side. Conicity angle of outer surface of wing is lesser than that of hull by 5-10 deg. Propeller is located in outlet section of nozzle or beyond it. Device for securing the nozzle to hull is made in form of cascade of radial blades twisting the flow before propeller and forming angle of 10-30 deg. with axial direction. EFFECT: enhanced propulsive properties and compensation of heeling angle due to operation of propeller. 2 dwg
