Description

The invention relates to devices for hitting an underwater target using an underwater warhead delivered by a rocket.

A known complex for hitting underwater targets at long ranges, RU No. 2371668 C2, made in the form of a ballistic missile (BR), in the bow of which is placed a winged missile (KR) under a deflected fairing; The BR contains aerodynamic surfaces with drives and an accelerating engine to ensure delivery of the RC to the firing range to the target area. The CR is docked with the accelerating engine by means of a separation device, configured to fly in the region of the target location and contains a detachable underwater warhead, as well as at least one detachable sonar buoy; the control system of the Kyrgyz Republic is equipped with equipment for receiving information from a radio-acoustic buoy via radio channel about the location of the target. For an economical flight in the atmosphere, the Kyrgyz Republic is equipped with a power plant with an air-jet engine.

The essential features of the proposed device that match the features of the prototype are the following: anti-submarine weapons device containing a cruise missile made with the ability to fly in the target area, docked by means of a separation unit with an accelerating engine and containing a power plant with an air-jet engine, a control system, a detachable underwater warhead and at least one detachable sonar buoy, while the control system is equipped with in the apparatus for receiving information from a sonobuoy about the whereabouts of the target over the air.

In the known device for the flight of the BR along a ballistic trajectory, the thrust of the BR engine must exceed its weight, which determines the high consumption and fuel supply of its propulsion system, including the high consumption of oxidizer, which is technically impossible to take from the atmosphere, and therefore, in addition to fuel, the volume of the BR is oxidizer reserve required for the flight. These factors increase the mass of the complex. In addition, during the flight of the BR, aerodynamic lift is not used, which additionally increases the required fuel consumption, its reserve in the composition of the BR and the mass of the complex. The large mass of BR complicates its manufacture, maintenance during operation, transportation and increases their cost, as well as facilitates opposition to enemy forces, which reduces the likelihood of hitting an underwater target.

The technical problem to which the proposed device is directed is to reduce its mass.

To solve the problem in an anti-submarine weapon system containing a cruise missile, capable of flying in the area of the target’s location, docked by means of a separation unit with an accelerating engine and containing a power plant with an air-jet engine, a control system, a detachable underwater warhead and, according to at least one detachable sonar buoy, while the control system is equipped with equipment for receiving information from the sonobuoy about the places when the target is located on the radio channel, the cruise missile is capable of flying at a firing range to the target location area, and the accelerating engine is made in the form of a launch accelerator, providing an increase in the speed of the cruise missile to a value sufficient to create aerodynamic lift supporting the flight and launch an air-reactive engine. For an economical flight on a marching section at altitudes of 0.05-15 km with a subsonic speed to the target area, the jet engine is made turbojet. For an economical flight on a marching section at altitudes of 10-40 km with a supersonic speed to the target area, the jet engine is made ramjet.

Distinctive features of the proposed device: a cruise missile is capable of flying at a firing range to the target location area, and the accelerating engine is made in the form of a launch accelerator, providing an increase in the speed of the cruise missile to a value sufficient to create an aerodynamic lift supporting its flight and launch an air-reactive engine; the jet engine is made turbojet; the jet engine is made ramjet.

Due to the presence of these distinctive features in conjunction with the known, the following technical result is achieved - the mass of the device, the time and money spent on its manufacture, maintenance during operation and transportation are reduced, the range of the possible range of destruction of the underwater target is expanded, and the likelihood of damage to the underwater target is increased.

The proposed technical solution can find application in the development of anti-submarine weapons of reduced mass and an extended range range, increased probability of hitting submarine targets.

The device is illustrated in the drawing, in which in the Kyrgyz Republic one of the variants of the jet engine is used - once-through (ramjet).

The anti-submarine weapons device is made in the form of KR 1, including a control system 2, steering surfaces 3 with actuators 4 in communication with the control system 2. KR 1 is equipped with a marching power plant containing ramjet 5, a fuel tank 6, a fuel supply line 7 to ramjet 5, containing a fuel metering device 8, in communication with the control system 2. KR 1 also contains a warhead 9 underwater with a device 10 for its separation, in communication with the control system 2, at least one radio-acoustic buoy 11 with a device 12 for its separation, in communication with the control system 2, including apparatus 13 for receiving radio waves, calculating the adjusted coordinates goals and definitions of the separation point of the warhead 9 underwater action, an accelerating device made in the form of a starting accelerator - a solid fuel rocket engine (solid propellant rocket engine) 14, located in the cavity 15 of the ramjet 5 and docked about 1 to SF through separation device 16. As an acceleration device, a carrier aircraft can also be used as the main acceleration device or additional. The ramjet 5 contains a multi-leaf adjustable jet nozzle 17. The orifice cavity 18 of the jet nozzle 17 of the ramjet 5 is connected to the atmosphere by a line 19 containing a shutoff valve 20 in communication with the control system 2.

The device operates as follows. The fuel reserve of the solid propellant rocket engine 14 is selected based on ensuring the acceleration of the rocket engine 1 to a speed sufficient to create aerodynamic lift supporting the flight of the rocket engine 1 and launch the ramjet engine 5. After the solid rocket engine burns out, the rocket engine 14 controls the separation unit 16, ensuring separation of the rocket engine 1 and rocket engine 14, which is released under the influence of excess air pressure in the cavity 15 of the ramjet 5. The control system 2 provides the launch of the ramjet 5 and the cruise flight KR 1 from the start point to the target area. Moreover, due to the fact that the marching propulsion system based on ramjet ramjet 5 uses atmospheric oxygen to burn fuel coming from the fuel tank 6 through the line 7 through the dispenser 8, the starting mass of the KR 1 decreases by several times due to a decrease in the required fuel supply on its board and, accordingly, reducing the mass of the power plant structure. The cruise flight of the Kyrgyz Republic 1 to the area of the marine target is carried out using aerodynamic lift, therefore, with low fuel consumption in the ramjet 5 and is performed at altitudes of 10-40 km. The use of ramjet 5 in a power plant provides an increase in the cruising speed of the KR 1 and reduces the flight time of the KR 1 to the target area. When a turbojet engine (turbojet engine, not shown) is used in the marching power plant instead of the ramjet 5, the low-cost march flight of rocket 1 to the sea target area, with low fuel consumption, is performed at altitudes of 0.05-15 km. The marching flight of CR 1 with a turbojet engine at low altitude reduces the visibility of CR 1 against the background of the Earth's surface, which reduces the likelihood of its detection and counteraction and thereby increases the likelihood of hitting an underwater target. The presence of a marching power plant based on an air-jet engine (ramjet 5 or turbojet engine) in combination with the possibility of maneuverable flight of the KR 1 in the atmosphere, provides a variety of flight paths of the KR 1 and delivery of the sonar buoy 11 and the underwater warhead 9 to both large and at short ranges, which extends the possible range of range of application of the device. The presence of a multi-leaf adjustable jet nozzle 17 makes it possible to activate the valve 20 to close line 19 after the KR 1 sets the altitude and speed of flight according to the command of control system 2, while the gas discharge from the suprastatic cavity 18 into the atmosphere stops, and the gases flowing through the gaps between the shutters of the jet nozzle 17 into the cavity 18, increase the pressure in it, under the influence of which the jet nozzle 17 is translated into a position with a minimum critical section. The decrease in the critical cross section of the jet nozzle 17 leads to an increase in pressure in the combustion chamber and the thrust of the ramjet 5, which allows the control system 2 by acting on the dispenser 8 to reduce fuel consumption from the tank 6 along the line 7 in the ramjet 5 and thereby further reduce the required fuel supply in the fuel tank 6, the mass of the tank 6 and the mass of the CR 1 as a whole. In the area of the location of the underwater target KR 1 separates at least one sonar buoy 11 by activating the device 12 of its separation. The presence in the KR 1 of several sonar buoys 11 allows, thanks to their location after splashing at a distance from each other with different angles of direction to the target with known own coordinates, to determine the coordinates of the underwater target with greater accuracy and to enable the device 10 to bring the warhead 9 underwater closer to the location of the target, which further increases the likelihood of its destruction.
