Abstract

FIELD: weapons.

SUBSTANCE: invention relates to a method for controlling the flight of a combat missile. In this method, the launch device with a missile (LDM) is placed in the immediate vicinity of the enemy's territory in a place hidden from enemy detection devices, in an underwater position at a depth of 100-300 m from the ocean surface. The launch of a combat missile is carried out when the LDM is located at a depth of 100 m. The LDM is performed with a base made in the form of an annular table with equipment with nozzles of propulsion motors for moving the LDM. When driven by LDM propulsion motors to the starting point by means of electrical connections between the base and the lifting cylinders, shut-off valves are opened to pass compressed air from the compressed air reservoir to the lifting cylinders under the pistons, due to which the pistons rise along the lifting cylinders. The upper part of the lift cylinders above the pistons is constantly in communication with the ocean water, and when the pistons are raised, the water is squeezed out of the upper part of the lift cylinders and the LDM rushes up. When the combat missile reaches the overwater position, the main engine of the combat missile is turned on and its flight begins along a pre-calculated trajectory, the LDM without a combat missile is lowered into a submerged position, and air from the lifting cylinders is again pumped into the compressed air reservoir. The flight control of the combat missile is carried out according to the program recorded in the onboard computer of the combat missile. If deviations of the actual trajectory from the programmed one occur, then the flight of the combat missile is corrected with the participation of the satellite navigation system. The programmed flight path of a combat missile has a variable course and altitude. Initially, the flight of a combat missile is aimed at a false target, upon approaching which the course of a combat missile changes sharply and it flies to a real target. The LDM radio station is turned on for reception at times according to a predetermined schedule and is additionally turned on by order from the command post. The pop-up antenna of the LDM radio station is constantly submerged and pops up only when the radio station is operating, and the radio station itself and the LDM computer are located on the base. Upon request from the command post, this radio station can transmit the coordinates of the LDM location and its operative condition with the participation of the LDM computer and the satellite navigation system receiver. When receiving information from the command post, the LDM computer selects the route of its movement, and also, with the participation of the onboard computer of the combat missile, selects the target and launches the combat missile. The transmission of coordinates to the command post is carried out with planned distortions. To obtain the actual values of coordinates, you need to know the correction factors, which are set in advance and depend on the date and time of day.

EFFECT: reducing material costs for a launch device with a missile (LDM), reducing missile flight time to the target, creating conditions that make it as difficult as possible to locate the LDM.

Implementation of the invention

For effective use of the BR 13, it is advisable to place it in close proximity to the enemy's territory in a place hidden from enemy detection devices. For this, the underwater basing of PUR 42 is suitable. To complicate the search for PUR 6 by enemy technical devices, it must move at a depth of 100-300 m from the ocean surface of PO 10. The radio station BUR 6 (not shown in Figs. 1, 2 and 3) is switched on for reception and can carry out short-term transmission of encoded information at the request of KP 4 about the coordinates of the BUR 6 and its good condition. In addition, the BUR 6 via radio communication receives information about the number of the target to be hit (for aiming the BR 13 at the target) and the missile launch time. PUR 6 has a minimum set of technical means for exchanging information with KP 4, determining the coordinates of the location of the BUR 6 using the satellite navigation system of the Russian Federation (not shown in Figs. 1, 2 and 3). The radio station BUR 6 works for reception at moments of time according to a predetermined schedule and can be additionally turned on by order from the CP 4. The pop-up antenna 9 is constantly in a submerged position and pops up only when receiving or transmitting information. The transmission of information about the coordinates (x, y, z) of the location of the BUR 6 to KP 4 is carried out with planned distortions. To obtain the actual values of the BUR 6 coordinates, it is necessary to know the correction factors, which are set in advance and take new values every 2 hours.

The flight path of the BR 13 from each zone (area with a radius of 200-1000 m) of its location to the target is calculated in advance and has a variable course and altitude. The initial flight path of the combat missile 7 corresponds to the decoy target 5, located at a distance of 100-300 km from the actual target. When the BR 13 approaches the false target, the BR 13 missile sharply changes its course and also continues its flight to the actual target in a zigzag manner (not shown in Figs. 1, 2 and 3). During the flight, the BR 13 is controlled only by the onboard computer in accordance with the selected program and the coordinates of the BR 13, obtained using the satellite navigation system of the Russian Federation. External electromagnetic fields do not affect the missile's course.

FIG. 1 shows a block diagram of the location of objects. On the territory of the first state 1 (the Russian Federation or a friendly state), as well as when sea-based in a submerged position, command post KP 4 is located with information exchange devices and antenna 8. In close proximity to the territory of the second state 2 (enemy territory) in a submerged position under the surface ocean PO 10 at a depth of 100-300 m a launcher with a PUR 6 rocket is placed. The launch of BR 13 is carried out when the PUR is at a depth of 100 m - the launch horizon of GZ 11. This makes it possible to carry out a high-speed ascent of PUR 6 to the ocean surface of PO 10. BR 13 rocket rises above the surface of the ocean 10, where the main engine BR 13 is turned on.

The maximum immersion horizon of the GMP 12 is 300 m below ocean level, which makes it possible to protect the BUR 6 from depth charges and from water pressure.

FIG. 2 and 3 show a side view and a top view of a launcher with a PUR 6 rocket, respectively.

According to the program embedded in the PUR computer, as well as by commands from KP 4, PUR 6 moves in a given zone with a change in the horizon (with the participation of the nozzle of the SD 38-41 propulsion engines). Before the launch of the BR 13, the PUR 6 receives information about the target number and the launch time. The on-board computer receives information and, at a given time, launches the BR 13 at a given target, taking into account the initial guidance of the BR 13 to a false target. At the same time, the PUR 6 is fed by means of propulsion motors (nozzles of the SD 38-41 engine) to the place from which the start will be made, ascends to GZ 11 and starts. In this case, the shut-off valves ZV 28-31 through circuits 33-36 receive an order to release air from the reservoir with compressed air РЗ 32, the air is passed into cylinders 14-17. Pistons 24-31 rise and squeeze water out of the upper parts of cylinders 14-17. The top of the cylinders is in constant communication with ocean water. BUR 6 rushes up. When the BR 13 enters the surface position, the main engine is switched on (not shown in Figs. 1, 2 and 3) and the BR 13 starts flying. PUR without a rocket is lowered into a submerged position. The lifting of the BR 13 in a submerged position is carried out with the participation of stops at 18-21 on the BR 13 and stops 22 and 23 on the BR 13 (only two stops are shown in Fig. 2). Then the air from cylinders 14-17 is again pumped into РЗ 32 and the PUR without a rocket goes down.
