Description

Air burst projectile bomb and bursting signal transfer device for air burst projectile bomb}

The present invention relates to an airburst bomb that reaches an explosion position and explodes in the air, and an airburst signal transmission device for projecting the bomb.

US registered patent US4,862,785 (registered on September 5, 1989) discloses a device for digitally adjusting a counter to activate a time fuse of an artillery shell. In this device, the transmission control circuit calculates the time to activate the time fuse of the shell by measuring the speed of the shell using the difference in detection time of the bomb passing through the two measuring coils with a known separation distance, and is placed at the rear of the two measuring coils. The time for activating the time fuse of the shell is wirelessly transmitted to the shell through the induction coil to set the counter of the shell.

However, in this technology, since all calculations, such as the calculation of the speed of the shell and the calculation of the time to activate the time fuse of the shell, are performed only on the device side, the time required for these calculations is between the two measuring coils at the front end and the induction coil at the rear end. Since must be sufficiently long, the length of the device has to be increased.

On the other hand, in Korean Patent Registration No. 10-2084670 (published on March 4, 2020), which was previously filed by the applicant of the present invention, a plurality of air explosion signal transmission devices are arranged at regular intervals along the cylindrical body, and information on the distance to the explosion position of the air explosion bomb is provided. Disclosed is an air explosion signal transmission device including a plurality of signal transmission units for transmitting multi-bit information including a to an explosion control system inside an air explosion passing through a cylindrical body.

Both ends of the plurality of signal transmission units are for speed measurement, and signal transmission units between the two signal transmission units for speed measurement are for inputting a distance to an airborne bomb explosion position.

The aerial explosive bullet calculates its speed using the time difference between the two signal transmission units for measuring the speed at which the distance is known in advance while passing through the cylindrical body of the air explosion signal transmission device, and the multi-bit (multi-bit) received from the air explosion signal transmission device. The distance to the airburst explosion position is obtained from multi-bit) information, the arrival time to the airburst explosion position is predicted, and the explosion timer inside the airburst is set.

In contrast to the above-mentioned U.S. patent, this technology inputs the distance to the explosion location of the air explosion signal transmission device, calculates the speed of the air explosion and predicts the arrival time to the explosion location of the air explosion. However, a plurality of signal transmission units transmitting multi-bit information including distance information to the airburst explosion position to the airburst bomb side are provided at regular intervals along the cylindrical body of the airburst signal transmission device. Since it must be arranged individually, this also had to increase the length of the air explosion signal transmission device.

Therefore, the present inventors studied a technique capable of miniaturizing the length of the airburst signal transmission device by simplifying the signal transmission structure for transmitting the distance information to the airburst explosion position on the airburst side.

The air explosion signal delivery device 100 according to the present invention may be implemented in a form detachable from the muzzle of a launcher (not shown), such as a silencer. As shown in FIGS. 1 and 2, the air explosion signal transmission device 100 according to this embodiment includes a cylindrical body 110, two permanent magnets 120, a transmission antenna unit 130, and a control unit. (140).

The tubular body 110 is a tubular portion of a cylindrical metal or high-strength non-metallic material through which the aerial bomb 200 passes. For example, the tubular body 110 may be attached to and detached from the muzzle of the launch pad (not shown). At this time, the diameter of the tubular body 110 varies according to the caliber of the aerial bomb.

The two permanent magnets 120 are spaced apart from each other in the cylindrical body 110 and apply magnetic signals for calculating the projectile velocity of the airburst 200. For example, one permanent magnet 120 may be disposed near the starting position of the cylindrical body 110 and the other permanent magnet 120 may be disposed near the ending position of the cylindrical body 110 .

At this time, the distance (L) between the two permanent magnets 120 is a known value, and the magnetic field sensor (described later) embedded in the aerial bomb 200 passing through the cylindrical body 110 is positioned at the position of the two permanent magnets 120. Since the detection time difference (t2 - t1) of the two magnetic field signals detected when passing through is a calculable value, the airburst speed (V = L / (t2 - t1)) on the airburst 200 side can be calculated.

The transmission antenna unit 130 is disposed in the cylindrical body 110 between the two permanent magnets 120, and the explosion control system inside the air explosive 200 passing the distance information to the explosion position of the air explosive bomb through the cylindrical body ( described later). At this time, the distance to the explosion position of the aerial bomb may be the actual distance to the target, but is not limited thereto, and may be a converted distance adjusted in consideration of the surrounding environment such as wind and the launch angle from the actual distance.

For example, as shown in FIG. 1, the transmit antenna unit 130 transmits a frequency-modulated signal including distance information to an airburst explosion position through magnetic induction or magnetic resonant coupling. ) method may be implemented in the form of a coil antenna that transmits.

Unlike this, as shown in FIG. 2, the transmission antenna unit 130 transmits serial data including distance information to the explosion position of an airborne bomb in a wireless serial communication method (a patch antenna) It may also be implemented in the form of a patch antenna.

The control unit 140 outputs distance information to the airburst explosion position to the transmission antenna unit 130. If the distance information to the airburst explosion position is an 8-bit signal, 256 distances (0m to 255m) can be output, and if a 10-bit signal, 1024 distances (0m to 1023m) can be output.

At this time, the control unit 140 may be implemented to output distance information to the airburst explosion position in the form of a frequency-modulated signal or in the form of serial data.

For example, the control unit 140 may include a modulator (not shown) for generating and outputting a carrier frequency modulation signal indicating a distance to an airburst explosion position.

Alternatively, the control unit 140 may include an encoder that generates and outputs serial data indicating the distance to the explosion position of the airborne bomb.

A signal including information on the distance to the airburst explosion position generated by the control unit 140 and radiated through the transmission antenna unit 130 is received through the reception antenna unit (described later) inside the airburst 200, It is used for estimating the arrival time to the explosion position of the aerial bomb 200 and setting the internal explosion timer.

As described above, the distance (L) between the two permanent magnets 120 of the air explosion signal transmission device 100 is a previously known value, and the magnetic field sensor embedded in the air explosion 200 passing through the cylindrical body 110 ( The airburst speed (V = L / (t2 - t1)) is calculated by calculating the detection time difference (t2 - t1) of the two magnetic field signals detected when the (described later) passes through the two permanent magnets 120 positions.

Then, by receiving a signal including distance information to the airburst explosion position generated by the control unit 140 of the airburst signal transmission device 100 and radiated through the transmission antenna unit 130, the airburst explosion signal is transmitted to the airburst explosion position. The distance (D) to the aerial explosive explosion position obtained from the side of the aerial explosive 200 having obtained the distance (D), and the arrival time (T = D / Estimating V), set the explosion timer inside the aerial bomb.

Accordingly, the present invention can reduce the length of the cylindrical body 110 by disposing the transmission antenna unit 130 having a simple structure and a small size in the cylindrical body 110 between the two permanent magnets 120. It is possible to solve the problem of increasing the length of the device, which is a problem in US Patent No. 4,862,785 and Korean Patent Registration No. 10-2084670 mentioned in the field.

By implementing in this way, the present invention can reduce the length of the airburst signal transmission device by simplifying the signal transmission structure for transmitting the distance information to the airburst explosion position to the airburst side.

In addition, in the present invention, since the air explosive can simply set its own explosion timer using the information on the distance to the explosion position of the air explosive that is input from the airburst signal transmission device having a reduced size, the explosion timer of the airburst can be set manually and directly. The inconvenience of setting can be eliminated.

Meanwhile, according to an additional aspect of the invention, the air explosion signal transmission device 100 may further include a shot detection sensor 150. The bullet detection sensor 150 detects an airborne explosive bullet 200 passing through the cylindrical body 110 .

For example, the shot detection sensor 150 may be installed at the front end of one permanent magnet 120 disposed near the starting position of the tubular body 110 . On the other hand, the shot detection sensor 150 may be implemented by a light sensing method comprising a pair of a laser diode (LD) and a photodiode (PD) or a magnetic induction method using a magnet, but is not limited thereto.

At this time, when the control unit 140 detects the aerial bomb 200 passing through the cylindrical body 110 by the bullet detection sensor 150, the distance information to the explosion position of the aerial bomb is sent to the transmission antenna unit 130. It can be implemented to output.

By implementing in this way, the present invention is that the control unit 140 transmits distance information to the air explosive explosive position through the transmission antenna unit 130 only when the air explosive 200 passing through the cylindrical body 110 is detected. By radiating toward the explosive bomb 200, it is possible to emit distance information to a precise aerial bomb explosion position.

On the other hand, according to an additional aspect of the invention, the air explosion signal transmission device 100 may further include a range finder 160. The distance measuring device 160 measures the distance to the airburst explosion position.

For example, the range finder 160 may be a laser distance sensor that measures a target distance by emitting a laser to a target (an airburst explosion position) and receiving a laser signal reflected from the target, but is not limited thereto.

At this time, the control unit 140 is implemented to output distance information to the airburst explosion position measured by the distance finder 160 to the transmission antenna unit 130, so that the distance to the airburst explosion position can be automatically input. there is.

At this time, the automatically input distance to the explosion position of the aerial bomb may be the actual distance to the target, but is not limited thereto and may be a converted distance adjusted in consideration of the surrounding environment such as wind and the launch angle from the actual distance.

By implementing in this way, the present invention can measure and automatically input the distance to the airburst explosion position through the distance finder 160, so it is inconvenient to manually calculate and input the distance to the airburst explosion position. and distance input errors can be improved.

The airburst speed is calculated, and the arrival time to the airburst explosion position is estimated from the obtained distance to the airburst explosion position and the calculated airburst speed, and an explosion timer inside the airburst is set.

At this time, the explosion control unit 330 determines the speed of the air explosion from the distance between the two permanent magnets 120 of the air explosion signal transmission device 100 known in advance and the detection time difference between the two magnetic field signals detected by the magnetic field sensor 320. It can be implemented to calculate

The distance (L) between the two permanent magnets 120 of the air explosion signal transmission device 100 is a previously known value, and the explosion control unit 330 is an explosion mounted inside the air explosion 200 passing through the cylindrical body 110. The magnetic field sensor 320 of the control system 300 detects the time (t1, t2) passing through the two permanent magnet 120 positions, respectively, and calculates the detection time difference (t2 - t1) of the two magnetic field signals to be detected. Calculate the airburst velocity (V = L / (t2-t1)).

In addition, the explosion control unit 330 receives a signal including distance information to the airburst explosion position radiated through the transmission antenna unit 130 of the airburst signal transmission device 100 through the reception antenna unit 310, The distance (D) to the airburst explosion position is obtained, and the arrival time (T = D / Estimating V), set the explosion timer inside the aerial bomb.
