Description

FIELD OF TECHNOLOGY

The claimed technical solution relates to military equipment, namely to devices for installing fuse shells.

BACKGROUND

From the prior art, devices for remote installation of fuses of shells are known, in which the transmission of installation signals occurs using inductive coupling between the installer and the fuse (patents RU No. 2064160; RU No. 2076303; RU No. 2086904; RU 4955279; RU No. 2359215; RU 253909 ); in this case, the projectile must necessarily have a receiver of transmitted installation signals. Such devices complicate the construction of the gun barrel and launchers of the launcher, which is described in the above patents: in the device according to the patent RU No. 2240495 for transmitting installation signals by an electromagnetic field to a charged projectile, holes are required in the tubular guides; in the device according to US patent No. 6170377 for the best penetration of the magnetic field from the installation device to the fuse, the part of the gun barrel should be made of non-magnetic material. Another common drawback of the above devices is the placement of the blocks of inductive signal transmission fuses on the outside of the barrel (guide). This increases the weight of the barrel (guide), and also exposes these blocks to the flame effect of rockets, which reduces the reliability of the device.

In all described devices, the electromagnetic signal is used as a carrier of the installation signals.

The purpose of the utility model is a remote automatic prelaunch installation of fuses of charged shells, using a normalized rate of fire, which does not require the placement of any blocks and devices on the surfaces of the barrel (guides), and also does not require changes in the design of the barrel (guides).

Known portable electronic temporary device 9P628 for installing fuses (installer) of rockets of multiple launch rocket systems (MLRS) in the prelaunch mode using an electromagnetic field. The specified device does not require any changes in the guides of rockets and does not need to constantly place any of its parts on the surfaces of the guides. To install the fuse for each shell requires putting on the installer on the head of the shell.

The device comprises: a control unit, an electric signal generator of the installation, a signal emitter of the installation.

This device is adopted as a prototype. Common signs of the claimed model and prototype is that their application does not require any changes to the guide, and also does not require the placement of any parts of the device on the surface of the barrel or on the guide. The reason that prevents obtaining the required technical result when using the prototype is that the specified device provides for the installation (programming) of the fuse only for a single shell during prelaunch preparation, which does not allow for the remote and automatic installation of fuses of charged shells and leads to high time costs , and also prevents the use of the specified device in the normalized rate of fire.

To achieve this goal, ultrasound is used as a signal carrier for the fuse installation, which is generated and modulated by the fuse programming signals in the installation device and transmitted through the metal parts of the gun and the projectile to the fuse. In this case, the programmable fuse of the projectile must contain a receiver that converts ultrasonic mechanical vibrations into voltage of the installation signals.

The successful use of ultrasound in devices for the remote transmission of information is known and disclosed in patents: US No. 59982297; US 20120182836; US 20110160582 A1; US20050036630 A1.

The use of ultrasound to remotely transmit information to projectile fuses is currently unknown.

To solve the problem, which is aimed at the technical result, the proposed device comprising a control unit, a signal generator for installing fuses, an ultrasonic signal emitter of the installation is introduced, which contains: an ultrasonic frequency voltage generator, a modulator, a matching amplifier, an ultrasonic frequency voltage converter into mechanical ultrasonic vibrations . In this case, the programmable fuse of the projectile must contain a receiver of ultrasonic mechanical vibrations, which converts these vibrations into electrical signals of the fuse programming voltage.

On command from the control unit, the setup signal generator generates a pulse voltage in which the fuse installation information is encoded. This voltage is supplied to the modulating input of the emitter modulator. The input of the carrier frequency of the modulator receives the voltage of the ultrasonic frequency of the generator. As a result, at the output of the modulator, ultrasonic frequency voltage fluctuations are generated, modulated by the fuse installation signals. After amplification by a matching amplifier, these voltage fluctuations are fed to the input of the ultrasonic transducer of the emitter, where they are converted into ultrasonic mechanical vibrations. The ultrasonic transducer of the emitter is mounted on the gun with pressed to the metal element of the barrel (guide). The direction of ultrasonic mechanical vibrations of the transducer should coincide with the direction of transmission of vibrations to the barrel (guide). Through the barrel (guide), through the charged projectile, through the fuse body, ultrasonic vibrations arrive at the input of the ultrasonic transducer of the fuse receiver. Ultrasonic mechanical vibrations are converted by the transducer of the receiver into voltage fluctuations, from which the electronic unit of the receiver extracts the fuse programming signals, which are stored in the electronic memory of this unit to perform the flight mission of the projectile.

A piezoelectric element is used as a transducer of electrical vibrations to ultrasonic mechanical vibrations using the inverse piezoelectric effect, in which an alternating voltage applied to the piezoelectric element is converted by it into elastic mechanical vibrations. To create more powerful ultrasonic mechanical vibrations that transmit installation signals, a magnetostrictor is used.

To convert ultrasonic mechanical vibrations into electrical vibrations, a direct piezoelectric effect can be used in the receiver.

The use of ultrasound allows the simultaneous installation of fuses with ultrasonic receivers of all the shells in the multiple launch rocket system, since all these shells are pressed against the guides by their own weight, which are interconnected by common metal fastening elements, such as membranes, and form a single metal structure. For the simultaneous installation of fuses with ultrasonic receivers of all charged MLRS shells, the ultrasonic transducer of the installation device is mounted on the common rail mounting unit so that ultrasonic mechanical vibrations of the converter are transmitted through guides and shells to all fuses with minimal losses.

In this case, the mechanical ultrasonic vibrations of the attachment point of all the guides reach the fuses of all the charged shells and perform their simultaneous installation in the pre-launch mode. The number of MLRS shells fired with the same installation of fuses is determined by the combat mission.

DISCLOSURE OF A USEFUL MODEL

The utility model is illustrated in the block diagram of FIG. one.

The device includes: control unit 1; signal conditioning apparatus 2; the signal emitter of the installation, which includes: an alternating voltage generator of ultrasonic frequency 3; modulator 4; matching amplifier 5; ultrasonic transducer installer 6.

IMPLEMENTATION OF A USEFUL MODEL

According to the firing data, from the control unit 1, the installation commands are sent to the input of the signal shaper of installation 2, which generates at its output a sequence of voltage pulses for programming the fuse. This voltage is supplied to one input of the modulator 4. An alternating voltage of the ultrasonic frequency from the output of the generator 3 is supplied to the other input of the modulator 4. At the same time, the alternating voltage of the ultrasonic frequency is modulated in the modulator by programming signals and is supplied to the output of the modulator 4 in the form of a modulated voltage of the ultrasonic frequency. From the output of the modulator 4, this voltage is fed to the input of the matching amplifier 5, the output of which is connected to the ultrasonic transducer 6 and matches the output voltage level of the modulator with the required voltage level for the transducer 6. The transducer transducer converts the ultrasonic frequency voltage signals that contain fuses programming information into the corresponding signals of ultrasonic mechanical vibrations. These vibrations are transmitted, as indicated above, through metal parts to the barrel or gun guides and are used to program projectile fuses located in the barrel or on the guides.

When using the proposed utility model for installing MLRS shells, the following procedure for installing pre-charged shells can be applied: fuses of all charged shells are installed according to the first identical program, then after launching the required number of shells with the first installation program, fuses of all remaining shells are installed according to the second necessary program, after the next launch of the required number, if necessary, the next program change occurs, etc. before launching the required number of shells.

Thus, the goal is achieved: remote automatic prelaunch installation of fuses of charged shells, using a normalized rate of fire, which does not require the placement of any blocks and devices on the surfaces of the barrel (guides), and also does not require changes in the design of the barrel (guides) .
