Description

The invention relates to systems for providing certain groups of foot soldiers with the required information in real time in areas of direct combat contact with the opposing side during police, counter-terrorism and other local operations, and in particular to their inexpensive disposable components in the form of ammunition for portable throwing devices, for example to individual and grenade launchers, small-caliber mortars, etc.

Considering the suddenness of the occurrence and the transience of operations in which airborne intelligence systems are used, one of the main requirements for them is to provide the largest field of view of the field of view for the greatest time.

The nomenclature of the main surveillance and reconnaissance systems, including airborne, is presented in the Foreign Military Review, 2011, No. 4, pp. 45-53.

From the above list of airborne reconnaissance systems, the American Huntir system with M1070 Huntir ammunition (p. 52) and the ammunition system based on a standard 81-mm illuminating mine (p. 52-53), which are selected as analogue and prototype for the present invention, respectively.

In the analogue of the M1070 Huntir, the ammunition, which is a container with a payload, is fired from individual and grenade launchers M79, M203, MilkorM32 and AG36 with a speed of about 100-110 m / s to the required height. At this height, the front cover is dropped from the container and a parachute is thrown out, which stabilizes the container and provides it with a smooth decrease at a low speed. During the container descent time, the IR camera located in it provides shooting in video or photo mode from the maximum height of the territory, equal to a circle with a diameter of 1.5 km. The received images are transmitted in real time to the field minicomputers of the grenade launcher and the commander of the squad or company.

From the description of the analogue, it follows that the following components are placed in the container of the shot ammunition:

- IR camera, which is located in the lower part of the container with the lens in the direction of the propellant charge of the munition shell;

- a parachute stowed in front of the container under its front dropable lid;

- a repeater with an antenna, the role of which is played by the aluminum case of the container, transmitting information (image) from the IR camera to field microcomputers;

- power supply of the camera and the repeater by electric current in the form of one or more batteries;

- a device for dumping the front cover of the container and ejecting a parachute from it, which is a small powder charge placed under the parachute;

- a remote initiating device to turn on the device for dumping the front cover of the container and ejecting a parachute from it at the required height;

- a device for connecting the power supply to the IR camera and the repeater by the time the parachute opens.

On the container, in order to protect the IR camera lens from the influence of hot powder gases of the propellant charge during firing, a rear cover is installed, which is dropped immediately after firing (leaving the grenade launcher barrel) or when the front cover is dropped and the parachute is ejected from the container.

The disadvantage of the analogue is the complexity of the device and, therefore, the unreliability of the entire structure. So, for example, a device containing two pairs of lockable, after firing, electrical circuits is included in the ammunition.

Another disadvantage of the analogue is the use of batteries as a power supply, because they have a limited shelf life and are unreliable at low temperatures.

The disadvantages of the analogue are partially eliminated in the prototype: an ammunition created on the basis of a standard 81-mm lighting mine.

To launch the prototype, a standard mortar is used, with which ammunition is thrown to a height of 550-600 m and a range of up to 5000 m.

The prototype consists of a casing in which a remote initiating device is placed in the form of a simple pyrotechnic moderator mounted in the bottom of the casing adjacent to this device of a powder charge, which destroys the casing at the required height (550-600 m) and throws a container with a parachute out of it. The container contains almost the same elements as in the analogue, however, instead of a video camera, a camera is installed and an additional self-destruction device is installed at the end of the work. The camera lens is closed by the back cover of the container, which protects the lens from hot powder gases of charge (towards which the lens is placed), which destroy the case and release a container with a parachute from it. The electric power supply unit also consists of batteries, and the electric circuits between the power supply unit and all equipment are closed using a special device only during the shot.

From the description of the prototype it can be seen that it has a simpler remote initiating device and a simpler connection with the powder charge, destroying the casing and emitting a container with a parachute from it, which increases the reliability of its operation and simplifies the design, however, in general, the prototype, like its analogue, remains a constructively complex and unreliable product.

The presence of a container self-destruction device in the prototype for this type of ammunition is an unnecessary and unnecessary complication of it, because this ammunition is used in fleeting operations and the enemy cannot take adequate countermeasures against the opposing side when capturing an exhausted camera.

The technical task of the present invention is to eliminate the disadvantages of the known munitions of airborne reconnaissance systems, similar to the analogue and prototype, namely, simplifying their design and increasing reliability.

The solution of the technical problem according to the invention is achieved by the fact that:

- in the munition of an air reconnaissance system containing the munition housing, in which a bottom remote initiating device is placed, an adjacent powder charge, fired from it and destroying the munition housing at the required height, and a container adjacent to the powder charge containing the housing in which the equipment is located photo or video recording, a repeater with an antenna for transmitting the results of the equipment to the ground control panel for their display and the power supply unit with electric current of the photo or video recorder traction and repeater, a parachute fastened to the container and placed above it in the cavity of the head part of the munition shell, the new thing is that the power supply in the initial state is electrically connected to the photo or video recording equipment and the repeater and is made in the form of a pyrotechnic current source installed by the end its pyrotechnic equipment to the powder charge, the photo- or video-recording equipment is placed at the opposite end of the container body with the lens towards the parachute, and between the parachute and the container a bracket is placed in the rum, the ends of which are located along the container and surround it from diametrically opposite sides, while the ends of the bracket are pivotally connected to the container in a place maximally displaced along the axis of the container body to its end, where the pyrotechnic current source is placed, while the parachute is attached with slings the jumper of the bracket, and the container is kept from moving in the longitudinal direction by the ends of the radial protrusions made in the head of the housing.

In a particular case:

- the bracket is made of spring sheet metal;

- if the container body is made of plastic, then the repeater antenna is formed by a bracket;

- the jumper of the bracket is equipped with a plastic or metal, made integrally with it, a reflector of the combustion products of the pyrotechnic current source, made in the form of a disk, the outer diameter of which is slightly smaller than the inner diameter of the housing.

The essence of the invention is illustrated by the drawing, in which Fig. 1 shows a sectional view of the ammunition of the invention, Fig. 2 and Fig. 3 are cross-sections of the ammunition in Fig. 1, Fig. 4 is a particular case of the execution of ammunition with a jumper strap equipped with a product reflector combustion pyrotechnic current source, and figure 5 is a cross section in figure 4.

Ammunition (see figure 1, 2 and 3) consists of a housing 1 and a bottom 2, which are fastened to each other by glue. In bottom 2, a bottom remote initiating device 4 is placed, a powder charge 3 triggered from it, and channels 15 are provided for the passage of powder gases into the cavity of the housing 1. A container 5 adjoins the powder charge, the housing of which contains a pyrotechnic current source 6, relay 7, photo- or a video camera 8. The container 5 is connected by a swivel joint 9 to a bracket 10, which, in turn, is connected by a jumper 11 to a parachute 12. The swivel joint 9 is formed by radial protrusions 13 that are maximally offset along the axis of the container body pa 5 to its end, where is situated a pyrotechnic power source, and under these holes 17 at the ends of the bracket 10. The head portion of the housing 1 provided with radial projections 14 that hold the container 5 from longitudinal displacement in the part of the munition.

If sufficiently large particles of hot slag are ejected from the combustion surface of the pyrotechnic current source, then the parachute 12 can be protected from them by a reflector 16 (see Figs. 4 and 5), made in the form of a disk with a diameter smaller than the inner diameter of the housing 1. The disk can be made of plastic and fastened with a jumper 11 of the bracket 10 or of metal and made integrally with a jumper 11. In this case, it is the reflector 16 in the form of a disk mounted with emphasis in the radial protrusions 14.

The work of the ammunition is as follows: when the throwing device leaves the barrel, the remote initiating device 4 fires, which ignites the powder charge 3 at the required height. The gases of the burning powder charge 3 pass through the channels 15 of the bottom 2 into the cavity of the housing 1, destroy the connection of the housing 1 and bottom 2 and disconnect them, simultaneously igniting the pyrotechnic current source 6. The current source begins to generate electricity, which is transmitted to the repeater 7 and the photo or video camera 8. After undocking, the housing a 1 and a bottom 2, a container 5 with a current source 6, a repeater 7, a camera or a video camera 8 and a bracket 10 out of the casing 1 and pulls the parachute 12. When opening, the parachute 12 holds the jumper of the extension bracket 11 with its slings, and the container 5, fastened with a bracket 10 by a swivel joint 9 (due to the displacement of the latter to the end face of the container body 5, and, therefore, remote from the center of mass of the container), rotates around the hinge axis by 180 degrees, providing the possibility of photo or video shooting.

From the description of the ammunition of the present invention it is seen that it:

- electrical circuits between the power source and all equipment are constantly closed;

- special protection of the lens of photo or video equipment is not required, as it is significantly removed from the place of combustion of the powder charge;

- a pyrotechnic current source and sufficiently reliable protection of the parachute from the combustion products of its equipment are used.

These technical solutions significantly increase the reliability of the ammunition and simplify its design.
