Description

Description of the invention

Underwater apparatus refers to ocean engineering and, in particular, to underwater engineering. 2 It is known about the automatic underwater vehicle "Scat-geo" with an aft propulsion module containing 4 propellers in nozzles located with the axis of the stop in a circle relative to the horizontal axis of the underwater vehicle | see Fig. b6b on page 194 in the book "Automatic underwater apparatus" / M.D. Ageev and others - / L.: Shipbuilding, 1981). Due to the lack of a central cruise propulsion module, the underwater vehicle has insufficient movement speed and maneuverability during an emergency dive to the working depth. 70 It is also known about the remote-controlled underwater vehicle "NOM" (Russia), which is an underwater remote-controlled video camera, a propulsion-rudder complex with 5 propulsion modules that provide control of its movement along all spatial coordinates | see Fig. 2 on page 75. Sea collection, Mo12, 2000). However, this underwater vehicle has a low underwater speed. In this regard, he needs to spend considerable time on descent and ascent to a great depth. Also, this underwater vehicle has insufficient maneuverability when increasing the power of the 12 propulsion modules due to the lack of peripheral propulsion modules.

The closest in terms of technical essence, essential features and the positive effect achieved to the claimed device is an underwater vehicle of the type DSRV (USA), which contains a strong body, which consists of three empty spheres connected in series. The central thruster, located in the stern, is presented in the form of a propeller in the nozzle | see Fig. on page 194 in the book by Voitov D.V. Underwater habitat apparatus. - M.. TOV "Izdatelstvo AST", 20021. However, this underwater vehicle has a low speed of travel under water due to the impossibility of installing a high-power power plant in the limited volume of the underwater vehicle, insufficient working time at great depth due to low speed of immersion, as well as low maneuverability at full underwater travel due to the presence of one cruise engine in the stern.

The useful model is based on the task of improving the underwater vehicle (UA), in which a number of propulsion modules are installed, located in the aft end of the UAV, thus increasing the speed and) improving its running qualities.

The task is solved by the fact that the underwater vehicle, which contains a strong body in the form of hollow spheres, connected in series by a transition hatch and placed in a light streamlined body, and/or cylinders with spherical ends, as well as a horizontal propulsion-rudder complex, located in the stern of the submarine, according to the utility model, is equipped with a horizontal propulsion-rudder complex with "With one or more central marching propulsion modules, installed with the axis of the thruster stop along the axis of the underwater vehicle, and a number of peripheral auxiliary propulsion modules with the thruster thrust axes placed around symmetrically with respect to the thrust axis of the central marching propulsion module. at

The positive effect is achieved by the fact that the central cruise propulsion module, located along the axis of the underwater vehicle, and a number of peripheral auxiliary propulsion modules, placed around it symmetrically with respect to the axis of rotation of the central propulsion module, allows to increase the speed of movement of the underwater vehicle, as well as to improve its running qualities due to the increase in total power. As an example, we can cite the net time for the descent and ascent of the underwater vehicle "Mir" to a depth of 5,200 m, which takes 8 hours, while the autonomy of the "TD" is 12 hours. Thus, there are 4 hours left for the "Mir" submersible 50 to perform work directly under water, which may turn out to be insufficient to perform the functional work of the submersible 50. To eliminate this shortcoming, it is necessary to reduce the time for the descent and ascent of the underwater vehicle

And" to the depth. This is possible by increasing maneuverability by increasing the speed of movement under water. So, in order to reduce the time of descent to a depth of 5200 m, the underwater vehicle of the "Mir" type needs to increase the speed of the underwater movement by three times. This is possible by using the proposed solution.

The essence of the decision is explained by the drawings: o - Fig. 1 shows the layout of the propulsion-rudder complex in the stern of the underwater vehicle with a strong av | body in the form of consecutively connected empty spheres, side view; - Fig. 2 shows the layout of the propulsion-rudder complex in the stern of an underwater vehicle with a strong hull in the form of a cylinder with spherical edges, side view. aw! 20 - Fig. 3 shows a diagram of the arrangement of the propulsion-rudder complex in the robust housing of the underwater vehicle, rear view. Co. An underwater vehicle containing a strong body 1 in the form of hollow bow 2 and stern C spheres (Fig. 1), connected in series by a transitional hatch 4 in a light streamlined body 5, and/or cylinders 6 with spherical ends 7 (Fig. .2), as well as a horizontal propulsion-rudder complex 8, located in the stern 25 of the underwater vehicle, consisting of a central marching propulsion module 9, installed with the thrust axis of the thruster along the axis of the underwater vehicle, and a number of peripheral auxiliary propulsion modules 10 with the axes of rotation of the thrusters , which coincide with the axes of thrust thrusters placed around the central marching propulsion module 9 symmetrically with respect to the thrust axis of the latter and parallel to it. A submarine may also have a ballast system, vertical nose, stern thrusters, and other necessary equipment, including a power plant, etc., which are not considered because of their traditionality and the insignificance of their impact on achieving the set goal. Propellers or jet engines of known designs can be used as engines,

For example, as in Fig. 30 on page 33 of the book by M.Ya. Alfer'eva "Ship Propulsion", volume 4, 1935 |.

The underwater vehicle works in the following way.

During the descent and ascent of an underwater vehicle, which contains a strong body 1 in the form of empty bow 2 and aft 3 spheres, connected in series by a transition hatch 4 in a light body 5 of a streamlined shape, and/or cylinders

6 with spherical ends 7, spatial maneuvering is carried out with the help of a tilt differential system and/or horizontal and vertical rudders (not shown in the figure) - changing the course of the underwater vehicle in the horizontal plane and changing the depth in the vertical plane. Propulsion-rudder complex 8 of the underwater vehicle carries out translational longitudinal movement due to overcoming the forces of resistance to the movement of the underwater vehicle as a result of the creation of thrust by the central marching propulsion module 9, established by the axis of the thruster stop along the axis of the underwater vehicle, and the simultaneous creation of thrust near the peripheral auxiliary propulsion modules 10 with axes thrust thrusters placed around the central marching propulsion module 9 symmetrically with respect to the axis of the latter thrust and parallel to it. Spatial maneuvering of the underwater vehicle in the water environment during descent and ascent, as well as when it performs work operations, is performed by the controlled operation of the peripheral auxiliary propulsion modules 10. The propulsion-rudder complex 8 allows you to control the movement of the underwater vehicle, because its efficiency does not depend on the speed of the longitudinal movement of the underwater vehicle. In some cases, the use of traditional means of controlling the movement of underwater vehicles, such as horizontal and vertical rudders, is impossible. In such situations, the only way out is the use of peripheral auxiliary drive modules 10.

In order to provide the same power for the propulsion-rudder complex of the underwater vehicle and maintain the same total mass, as well as the same overall dimensions, it is necessary to use 2.5 times more electric motors of smaller dimensions. This allows you to increase the speed of the underwater vehicle by approximately 2 times. For example, the same type of electric motors GSR-Z000 and GSR-6000, see table 2.17 on page 89 in the book Kazarezov

A.Ya., Gal A.F., Pishnev S.M. "Designing devices and systems of underwater vehicles". Mykolaiv: NUK, 2005. - part 1| have, respectively: shaft power - 3.0 (6b.0) kW; mass - 9.5 (17.5) kg; overall dimensions - 2207144 (3107166) mm. One kW corresponds to 3.17 (2.86) kg of mass or one kg of mass - 0.095 (0.28) kW. At the same time, the volume of electric motors, respectively, for the GSR-3000 is equal to 3581107.2mm "Z for the GSR-6000 is equal to 6705752.6mm'Z. In this way, 376958.6Z (383185.9)mm'" is obtained for one kg of the mass of each electric motor, respectively. or by one mm'? 26.571077 (26710-7) kg of mass is found, respectively. In addition, for one kW of power of each electric motor, 11937024 (11 17625) mm "Z is calculated, or for one mm'Z, 8.4710-7 (9510-7) kW is calculated, respectively. Therefore, the generalized indicator for overall dimensions at the same power and mass will be equal, respectively, for the first and second types of electric motors

From 26,5710-7:8,471077-222,6710714. (2671077х9х1077-2347107143, Thus, the universal indicator for the same power, mass and dimensions for the selected types of electric motors is equal to 0.37222.67107171-66.78710714 (0.85234710714 -187.271071), Hence for in order to provide, for example, a power of 100 kW, 6,678 (77) pieces of electric motors of the GSR-3000 type are needed, and while maintaining the same mass and

35 dimensions - 18.72 (19) pieces of electric motors of the GSR-6000 type, that is, 2.8 times more. Conditionally, it can be assumed that while preserving the overall dimensions and total weight of the electric motors, with the partial use of (5095) one type and 5095 of another type of electric motors of greater power, the speed of the underwater vehicle can be increased by approximately 2.5 times.

The positive effect, which allows you to increase the underwater speed of the underwater vehicle, as well as improve its running qualities and maneuverability at full speed and reduce the time for descent and ascent, is achieved by the fact that the underwater vehicle is equipped with a horizontal propulsion-rudder complex containing the central marching propulsion module 9, set with the thrust axis of the thruster along the axis of the underwater vehicle, and a number of peripheral auxiliary )" propulsion modules 10 with the thrust axes of thrusters placed around the central marching propulsion module 9 symmetrically relative to the thrust axis of the latter and parallel to it. at
