Description

The invention relates to the field of military equipment, and more specifically to devices for programming remote fuses of shells in the automatic mode of firing from pre-charged multi-barrel combat vehicles of multiple launch rocket systems.

Known devices (installers) for contactless programming of fuses (US patent No. 4022102, IPC F 42 C 17/00, publ. 05/10/77; US No. 5241892, MPK F 42 C 17/00, publ. 07.09.93; US No. 6170377 IPC F 42 C 17/00, published 01/09/2001; US No. 6189430, USCl. 89 / 6.5, publ. 02/20/2001; European patent EP No. 0894236, IPC F 42 C 17/00, F 42 C 17 / 04, published January 9, 2001; EP No. 0965815, IPC F 42 C 17/04, published December 22, 1999; RU No. 2064160, IPC F 42 C 17/04, published July 20, 1996; RU No. 2066443, IPC F 42 C 17/04, publ. 09/10/96). These devices provide non-contact programming of the fuse of a single artillery shell in preparation for firing (autonomously before loading the gun, on the automatic loader before sending the projectile into the gun’s barrel), after a shot when the projectile moves in the barrel or behind its muzzle. Due to the design features and tactics of the combat use of multiple launch rocket systems, these devices cannot be used for contactless programming of remote fuses of rockets located in the guides (trunks) of pre-charged multi-barrel combat vehicles.

Known installer of an electronic remote fuse (patent RU No. 2066442, IPC F 42 C 17/00, publ. 09/10/96). comprising a mode switch, serially connected a signal generator of a setup (programming), a signal monitoring unit, a flight time calculation unit, a transceiver device, a control unit for an indication unit and an indication unit. The setup (programming) signal generator consists of an AND circuit, two amplifiers, connected in series by a pulse shaper (generator), a counter, a duration shaper, a switch, and the windings of the transmitting device. The specified installer is taken as a prototype.

The reasons that prevent obtaining the required technical result when using the prototype are that the installer provides installation (programming) of the fuse with an inductive control circuit of only a single projectile when it is fed into the breech of the gun (when loading), which leads to a long programming time of the fuse and, as a result, to reduce the rate of fire; a projectile feeding (loading) mechanism is required; excludes the possibility of non-contact programming of a fuse of a charged projectile.

Common features of the invention and said installer are the presence of a control unit, a signal control unit, and a signal shaper of the installation (programming), consisting of a generator and a power amplifier.

The problem to which the invention is directed, is to ensure the formation and delivery of signals to information transmitting devices installed on each guide of the combat vehicle for programming fuses with an inductive control circuit directly in the automatic mode of firing shells with a normalized rate of fire from a pre-charged combat vehicle. In this case, the codes of programming parameters and guide numbers corresponding to the established sequence for launching shells are issued by the launch equipment of the combat vehicle and are received automatically by the device without stopping firing.

The output 26 of the information exchange unit 1 is connected to the decoder 2, the first output of which is connected to the input 27 of the ROM 4, and the second to the input 28 of the RAM 5 of the microprocessor 3 of the control unit. The output of the ROM 4 is connected to the input 29 of the RAM 5, the input 30 of the decoder 11 and the input 31 of the multiplexer 12 of the switch 10. The outputs of the multiplexer 12 are connected to the inputs 32 of the transistor key 15 of the additional switching cell 14 and the inputs 32 (1) -32 (N) of the transistor keys 15 (1) -15 (N) switching cells of the guides 13 (1) -13 (N).

A device for contactless programming of remote fuses of rockets of multiple launch rocket systems works automatically according to the control commands AP 18 combat vehicle as follows. With the supply voltage, the microprocessor 3 of the control unit and the signal processor “programming 38” are started. The carrier frequency 42 is transmitted from the output of the generator 6 to the modulator 7. Upon receipt of the combat vehicle from the AP 18, the input information block 1 of the readiness request code 43 from the outputs of the decoder 2 signal 44 enters the input 27 of the ROM 4 and signal 45 to the input 28 of the RAM of the microprocessor 3. From the output of the ROM 4, the signal 46 is of a duration shorter than the normalized rate of fire, counted by the timer 40, is fed to the input 29 of the RAM 5, the inputs 30 of the decoder 11 31 of the multiplexer 12 of the switch 10. From the output of the multiplexer 12 (if the readiness codes in the ROM 4 and received from the AP 18 match), the signal 47 is transmitted to the control input 32 of the transistor switch 15 of the additional switching cell 14. The transistor switch 15 opens, the switch 16 is activated and connects the first output of the comparator 9 to the switching input 35 of the managed switch of the cell 14 and from its output to the input of the simulator-equivalent of the information transfer device 17 for the time counted by the timer 40. From the output of RAM 5 to the input 33 of the modulate Ora 7 and the input 34 of the comparator 9 are given pulses 48, which are filled in the modulator 7 with a carrier frequency 42 of the generator 6. Through the power amplifier 8 from the first output of the comparator 9 and the switching element of the controlled switch 16 of the cell 14 to the input of the simulator-equivalent 17 receives a test programming command 49 .

When the parameters of the test programming command are set to the current and voltage values from the second output of the comparator 9, a signal is output to the input 36 of the microprocessor 3, which is converted by the microprocessor 3 into a ready response command code coming from the output of the microprocessor 3 to the input 37 of the information exchange unit 1 and from its output 25 readiness response code 50, issued by AP 18. If the parameters of the test programming command do not correspond to the specified values, the signal from the second output of the comparator 9 to the input 36 of the microprocessor 3 is not given out.

If the output 25 of the information exchange unit 1 readiness response code 50 AP 18 automatically outputs to the input 24 of the unit 1 programming parameter code 51 fuses 22 (1) -22 (N). From the second output of block 1, the programming parameter code 51, through the second output of the decoder 2, is supplied in the form of a signal 52 to the input 29 of the RAM 5. The parameters to which the fuses should be programmed are recorded in the RAM memory. When the signal 52 is received, the microprocessor 3 converts it into a response code 53 for receiving programming parameters, which is fed to the input 37 of block 1 and from its output 25 to AP 18.

If there is a response code 53 AP 18 goes into automatic sequential launch of shells with a period corresponding to the normalized rate of fire. At the input 24 of block 1 from the AP, the guide number code 54 (1) -54 (N) is sequentially issued, from the second output of block 1, signals 55 (1) -55 (N) received at the input 26 of decoder 2 and from its first output are also sequentially fed to the input 27 of the ROM 4 of the microprocessor 3. If the code of the guide number recorded in the memory of the ROM 4 and issued by the AP 18 matches from the output of the ROM 4 to the input 29 of the RAM 5, the inputs 30 of the decoder 11 and 31 of the multiplexer 12 of the switch 10 give signals 56 ( 1) -56 (N) duration counted by timer 40.

For each signal 57 (1) -57 (N) from the output of the multiplexer 12 to one of the inputs 32 (1) -32 (N), the transistor switch 15 (1) -15 (N) of the switching cell 13 (1) -13 (N ), the number of which corresponds to the adopted guide number code, opens, its controlled switch 16 (1) -16 (N) is activated and the first output of the comparator 9 is connected to its switching input 35 (1) -35 (N) and, accordingly, to the input 39 (1) -39 (N) of the information transmission device 19 (1) -19 (N) on the selected rail. According to the code of programming parameters 51 recorded in the memory of RAM 5 of microprocessor 3, the pulses 58 (1) -58 (N), the duration of which corresponds to the programming parameters, are output to the inputs 33 of the modulator 7 and 34 of the comparator 9. The carrier frequency 42 of the generator 6 is simulated by pulses. From the output of the modulator 7 and the power amplifier 8, the first output of the comparator 9 and the switching element of the managed switch 16 (1) -16 (N) of the switching cell 13 (1) -13 (N) of the switch 10 is a programming signal 59 (1) -59 (N) enters the input 39 (1) -39 (N) of the information transmission device 19 (1) -19 (N) of the selected guide. The information transfer device creates an alternating electromagnetic field, which is perceived by the fuse receiver 22 (1) -22 (N) and is converted by its circuit into programming signals.

Upon the passage of information to the transmission device, the selected guide signal of the programming signal and when its parameters match the specified values from the second output of the comparator 9 to the input 36 of the microprocessor 3, a signal is issued. The microprocessor 3 converts it into a resolution command code 60 (1) -60 (N), which is fed to the input 37 of the information exchange unit 1 and from its output 25 to the AP 18, which automatically issues the command 61 (1) -61 (N) to igniter 23 (1) -23 (N) for starting the projectile engine 21 (1) -21 (N) from the selected guide 20 (1) -20 (N). If the programming command 59 (1) -59 (N) did not arrive at the information transmission device 19 (1) -19 (N) or its parameters do not correspond to the specified values, then the signal from the second output of the comparator 9 to the input 36 of the microprocessor 3 is not issued, and the permission command code 60 (1) -60 (N) at the output 25 of block 1 is missing.

If necessary, in case of a change in the combat mission, the device provides the ability to change the programming parameters of any fuse without stopping the launch of shells with a normalized rate of fire. Moreover, with the arrival of changed codes 51 from the AP, the programming parameters are automatically updated in the memory of the RAM 5 of the microprocessor 3 and the command device works in a similar way.

Thanks to the device, the tactical and technical characteristics and efficiency of multiple launch rocket systems are significantly increased due to the fact that remote fuses are programmed contactlessly directly in the automatic projectile launch mode with a normal rate of fire in a given sequence, while it is possible to change the parameters of the fuses programming without stopping firing. High tactical and technical characteristics of multiple launch rocket systems are confirmed by numerous tests.
