We offer submersible enhanced agility is illustrated by the drawings shown in figs.1-4.

Fig.1 shows a perspective view of the submersible enhanced agility.

Fig.2 is a longitudinal section a-A underwater vehicle with advanced maneuverability.

Fig.3 - cross section b-b underwater vehicle maneuverable.

Fig.4 is shown a hydraulic propulsion.

Underwater vehicle maneuverable contains the streamlined body 1 in the form of drops, the window 2, a vertical water inlet 3, Luke 4, guides 5 and frame 6. The body 1 and made of durable stainless steel. Propulsion system includes a water-jet pipe (front 7, right 8, fodder 9, left, 10, and 11 Central), �the output nozzles 12 disposed in the cavity of a vertical water inlet 3, and output connections 13 are accommodated in the housing 1. In the area of the output nozzles 13 in a water-jet tubes 7, 8, 9, 10, 11 installed generators 14, the hydraulic propulsion motors 15 and 16 (Fig.1 and 2). Hydraulic thrusters 15 is formed as a hollow helical surface and have a rectangular cross-section (sides a and 2A) and the walls of the blade is twisted along the length at an angle from 0 to 180°. Guides screens 5 are in the shape of a round bowl and with a gap (the gap between the surface of the body 1 and the hollow guide screen 5) rigidly fastened to the housing 1 in the output zones of water-jet nozzles 13 pipes 7, 8, 9, 10, 11. Guides screens 5 made of durable flexible plastic, not prone to biofouling. In the lower compartment 17 of the housing 1 is placed a container 18 with switching protection and electrical distribution equipment and the container 19 with batteries. The upper compartment 20 posted 21 remote management and control of the apparatus (Fig.3). Fig.4 shows the hydraulic propulsion unit 15 in the left 10 water-jet pipe, where the shaft 22, bearings 23 and streamlined strut mounts 24.

Work underwater vehicle maneuverable as follows. Submersible enhanced agility has a support 6 for installation on boats with a crane. Before diving, you should charge the battery�, placed in the container 19 of the lower compartment 17, and test the switching protection and power distribution equipment placed in the container 18. Crew members through the hatch 4 is lowered into the upper compartment 20 of the housing 1 and take jobs at the control panel 21 of the management and control of the apparatus in front of the window 2. Consider the work of the propulsion complex. On 21 remote management and control withdrawn Executive devices control the operation of the propulsion complex. The battery runs the electric motor 16 which rotates the shaft 22 (placed in the bearings 23 with mounts 24) of the hydraulic propulsion unit 15 and the electric generator 14. Next, consider the movement of water when the motor 16, for example, left 10 water-jet pipe (the other water pipes 7, 8, 9 and 11 are identical). Water through the Windows of the vertical inlet 3 flows through inlet nozzle 12, and then she is captured by a hydraulic propulsion unit 15, and accelerated swirling flow through the outlet 13 is discharged into the cavity of the guide screen 5 and spreads over its surface. In the gap between the surface of the body 1 and the hollow guide screen 5 there is an inhomogeneous velocity field. This flow will occur inertial forces, which will create a depression on the surface of the housing 1, �have a quiet and lead to movement of the apparatus to the right. The magnitude of this driving force depends on the flow velocity and area guide screen 5. The basis of this justification is the Coanda effect (energy-source.ru/-iv-/s19-.html G. Smirnov, "Born of the whirlwind, 1982). Maneuvering apparatus at the work of other water-jet pipes: front 7 - the machine moves backwards; right 8 - the apparatus is shifted to the left; fodder 9 - the machine moves forward; Central 11 - device is shifted up. Falls down due to the negative buoyancy. When working hydraulic thruster 15 generator 14 generates alternating electric current, which is rectified and charges the battery. There is a constant recharging of batteries.

The use of the device allows to reduce the power consumption of the propulsion complex, the unit is lighter in weight, easier to manage and has a high degree of manoeuvrability.
