Abstract

FIELD: armament, in particular, control systems of artillery guided missiles with a laser guidance.

SUBSTANCE: the complex has a correctable artillery missile with a semi-active homing head and a flying mission setter functionally bound up with the firing tables. The complex is provided with communication radio sets, laser target indicator-range finder with an "own" code setter conjugate to the receiving channel of the communication radio set, and an airborne transponder, which is installed in the correctable artillery missile for transmission of a signal of "ready" to reception of the flight mission after the shot after a time limit to the receiving channel of the communication radio set. Besides, the transponder provides for a subsequent reception of information on the approach time and information on the "own" code via the transmitting channel of the communication radio set, as well as for transmission of the respective "own" code and the command for actuation of laser radiation on expiration of the approach time from the transmitting channel of the airborne transponder via the receiving channel of the communication radio set to the laser target indicator-range finder.

EFFECT: automated process of guidance of a correctable artillery missile, enhanced antijamming capability and reduced time of preparation at missile loading.

Description

The invention relates to high-precision artillery weapons. Known [1] artillery complex for firing 155 mm guided artillery shell (UAS) "Copperhead".

The disadvantage of this complex is the need to load four switchings for installation: fuse mode, start time, homing code and autopilot program, and errors in the installation of the last two can lead to deviations of several kilometers.

The UAS is equipped with a homing gyrohead, planning autopilot, steering gears, which reduces the reliability of the complex and requires periodic monitoring. The UAS requires a 15-second laser backlight, which reduces the noise immunity of the complex.

Known [2] is a method of firing an artillery guided projectile, including setting a pre-firing code corresponding to the selected portion of the firing ranges, according to which, during the flight, the time intervals wired into it are read from the read-only memory device to activate the on-board systems. The disadvantage of such an electronic mission transmitter is the need to mechanically set the code on the UAS three-toggle register before firing, in addition, the on-board electronic controller does not ensure the timely launch of the laser rangefinder.

This complex is adopted as a prototype.

The objective of this technical solution is to automate the guidance process, increase the noise immunity of the complex, reduce the preparation time when loading a projectile. The task is achieved by the fact that the composition of the complex of corrected artillery weapons with laser guidance, containing the corrected artillery shell (CAS) with a semi-active laser homing head, configured to record the CAS flight time from the moment of the shot by means of an electronic temporary device, and an electronic mission assignment unit, functionally associated with firing tables, connected radio stations installed at the command and observation point and firing it, a laser target designator-range finder with an installer of “its own” code, paired with the receiving channel of a connected radio station, and an airborne transceiver installed in the CAS with the possibility of issuing after a shot after a specified time to the receiving channel of a connected radio station installed at the firing position, the signal is “ready ”To receive the flight task and the subsequent reception through the transmitting channel of the connected radio station of information about the flight time and information about“ their ”code, as well as transmission after the flight time from the transmitting channel of the onboard transceiver through the receiving channel of a connected radio station to a laser target designator-rangefinder of the corresponding “own” code and the command to turn on the laser radiation.

The novelty and inventive step of the proposed complex is determined by the introduction of devices to automate the process of generating and transmitting a flight task using an electronic master located on the base station through the transmitting channel SR to the UAS, the introduction of a base station that provides a readiness signal for receiving a base station, receiving a base station and issuing a launch command LCD, also the introduction of devices that ensure the development of only "their" codes.

The proposed complex according to the structural diagram shown in the drawing contains a corrected artillery shell 1 with a laser homing head 2, an electronic temporary device 3 and an airborne transceiver 4, at a command and observation point 5, a laser target designator-rangefinder 6 with a connected radio station 7, at a firing position 8 electronic master 10 with a connected radio station 9. The proposed complex operates as follows. Before the shot, according to the initial data about the target (IDC) and the “own” code of laser radiation (LI) entered into the electronic controller 10, a flight task is programmed using firing tables. After a regulated time after the moment of the shot, the on-board electronic temporary device 3 generates a “Ready” signal for receiving the PZ, which is transmitted through the on-board transceiver 4 to the receiving channel of the connected radio station 9, coupled to the electronic master 10, in response to which the PZ through the transmitting channel of the connected radio station 9 comes in the form of a radio signal to the input of the airborne transceiver 4, and then in the form of a digital code in the EVU 3. After the flight time specified in the PP expires from the EVU 3 from the transmitting channel of the airborne P 4 through a reception channel connected to the input station 7 is supplied by the LCD 6 corresponding to "his" code and the command to switch the laser HF.

The proposed complex allows you to automate the guidance process, ensuring optimal time interaction between CAS 1 and LCD 6 at the beginning of CAS 1 homing, increasing the noise immunity of the complex during guidance, reducing the time of preflight training, and also monitoring the information received for the presence of “your” codes.
