[Detailed description of the invention] The second invention of a weapon fuse readiness timing device, especially for automatic firearms, is This invention relates to a device for preparing and timing the fuse of ammunition that During a series of firing with a single grenade launcher (a so-called grenade launcher) A device for measuring time, which consists of one fuse, a timing element, a transmission means, etc. The fuse consists of an electrically ignited percussion cap and at least one An ignition element with a supply capacitor and a fuse during or at the end of a specific time interval. It has an electric timing circuit that controls the ignition of the bomb, and the ammunition cartridge or ammunition supply means. said time-measuring element attached to said time interval is connected to a power supply and said time interval selection means is connected to said time interval; The transmission means is electrical or magnetic between the timing element and the fuse before firing. A composite signal is transmitted to the fuse via a transmission circuit, and this composite signal is transmitted to the fuse. supply energy to charge the capacitor and pulses indicating the above time intervals. It provides at least one signal.

by a pair of surface electrical contacts placed on the ammunition to delay the fuse. It is already known that a complex signal is transmitted to a delayed fuse; Electrical energy and digital meter for single or continuous drive It is designed to provide time information.

The working principle of such a device is described, for example, in French patent application FR-A 2591327. and external chronometer fuses for small or medium caliber ammunition. An electrical connection is provided with the control device. This connection communicates to the fuse. The composite signal provides the digital clock signal and the electrical energy to be stored in the fuse. It consists of continuous elements that supply Described in U.S. Patent No. 4,424,745 needs to receive a signal through one electrical line, but this signal is It consists of electrical energy for the fire and timing information. However, this information is analog It is transmitted in the form of an energy signal and is integrated into the fuse itself after the energy is It is converted into digital form by an appropriate electrical circuit.

However, all of these devices suffer from interference from electrical or electromagnetic influences. This poses some risk as the events are being prepared or delayed.

This invention aims to eliminate these drawbacks by providing a simple and durable device. This allows the timing to be continuously corrected during firing when used on automatic weapons. The goal is to accurately and reliably measure time quickly.

For this purpose, the present invention proposes the above-mentioned device, in which the above-mentioned composite signal is The electronic fuse itself has at least one electronic lock and The lock is provided with decoding means for receiving a matching code signal and opening the lock.

In a first embodiment, the transmission circuit includes two pairs of transmission circuits, one on the ammunition and one in the timing device. It has electrical contacts.

In other embodiments, the transmission circuit includes a magnetic circuit surrounding the coil in the timekeeping device and an elastic circuit. It has a coil placed inside the medicine.

In a preferred embodiment, the composite signal sequentially delivers electrical energy to the fuse. a charging signal to be applied, a code N, and at least one pulse signal representing a time interval. have. Also, the composite signal consists of two consecutive pulse codes indicating the beginning and end of the interval. It may also have a code.

and needs electronic unit preferably to control fuse ignition and decoder has an electronic interrupter associated with the electronic lock which is controlled by two time intervals If the electronic unit is represented by a pulse signal, the electronic unit immediately receives the pulse signal. It has two counters connected in columns. Electronic locks are these counters connected between. Additionally, fuses usually have a shock switch, and an electronic rotor. A switch is connected between this A5 strike switch and an electronic interrupter.

The timing mechanism includes two manual control means, which control each pulse signal. Define the value of the number.

The manner of carrying out the invention will be explained in more detail in the following appended sections.

FIG.

In Fig. 1.2, a ammunition cylinder 1 is used for firing or rapid firing ammunition 2 supplied in the form of a strip. It is something that This is a well-known military weapon that comes in various forms, including hand-held and vehicle-mounted. There is something. Although such weapons do not rely on fire control systems, this invention attempts to provide a simple construction preparation device that can be manually controlled by the shooter or observer during shooting. It is something to do.

The ammunition 2 has a dome-shaped tip 4 equipped with a fuse 5 and a metal cartridge-type case 3. have. The tip 4 has a metal contact separated by an isolation ring at its tip. 6.

This fuse 5 has a contact 6 forming part of the fuse on the one hand and a ground contact 6 on the other hand. The case 3 is electrically connected to the case 3 which acts as a casing. instead of element 3.6 Two parallel annular bands encircling the center of the ammunition separated from each other may also be used. stomach.

The trajectory of the ammunition shown in FIG. It has three consecutive phases consisting of i.

Special table 13-501517 (3) To is a steady-state safety period for opening, during which ignition does not occur.

T is a selectable variable period that is added to To to postpone the ignition lock period until point 10. After this time, the fuse is ignited by the switch during the period Tl. Tl also selected is an option period and is added to the periods To and T, and when the shock has not yet occurred. This is to determine the ignition point 9.

This principle is well known and has been applied to a variety of ammunition types. Hugh's If the period To is set to a constant value by the structure, the timing mechanism will calculate the values of T and T in the fuse. It consists of memorizing. The above device is used just before the ammunition enters the crucian cartridge, especially during the explosion. This work is done in the

'In the cartridge shown in Figure M3, the ammunition 2 is attached to the feed belt 12 just like a machine gun. Powered by. This belt passes through a timing mechanism 13 equipped with a power source 14.

This power source can be an automatic generator, dry battery, or storage battery used in transportation vehicles, etc. Appropriate.

This timing mechanism 13 stores the value T+%T in the fuse 5 of the ammunition 2. The value can change from one ammunition 2 to the next during the same rapid fire.

These values are represented by a composite coded signal, which is sent to the clock mechanism 1. 3 to each fuse 5. This transmission is carried out by an electrical circuit between two contacts. This is done through a contact means such as a thin plate. As the ammunition passes through the timing mechanism 13, it contacts the surface of its element 3.6.

Although the timing mechanism 13 is shown as being independent from the ammunition cartridge 1 in the figure, the two can be combined together. Of course, it may be configured. The shooter operates two manual selectors 15 and 16. two electrical selectors that operate and determine the periods T+, To in the digital electronic unit; - excite. In this example, the selectors are rotary buttons with 17 markings on each button. ．． 18 is attached. Of course, instead of using a scale like this, which direction is increasing? It is sufficient to simply provide a mark to indicate whether the clock is in the correct direction or not. A digital display section is also provided to display To + TI + rt.

In Fig. 4, the output part of the electric circuit of fuse 5 is composed of two terminals 21 and 22. and these terminals are connected to element 6.3 on the ammunition and terminal 22 is connected to element 6.3 on the ammunition. is being sourced.

This circuit has an electronic circuit 23, of which an interrupter, such as a thyristor, is , when the fuse is connected to the ground conductor 26, the explosion voltage of the fuse 25 Controls vapor ignition. The electrical energy that ignites fuse 25 is supplied by capacitor C. 2, and this charge flows into the conductor 27 through the safety interrupter of the switch 28. It will be done. This switch 28 remains open until a shot is fired and then remains closed. Controlled by a mechanism.

This ignition capacitor C2 is connected via two diodes 30, 31 to the input terminal 21. It is interposed between the terminal 29 connected to the ground and the ground. electronic unit 2 A second capacitor 02 that supplies power to terminal 3 is interposed between the ground and terminal 32. This terminal 32 is arranged between the diodes 30 and 310 and is connected to the electronic unit 23. It is connected to the supply terminal 33 of. The other input terminal 34 of the unit is connected to the conductor 35. It is directly connected to the terminal 31 to receive the polarity signal. Between the conductor 35 and the ground A resistor 36 is interposed to ensure gradual discharge of the residual voltage. Terminal 29 is a die It is connected to the other input terminal 38 of the unit 23 through the output terminal 3 and receives a command. Terminal 38 is configured to discharge the capacitor when

An electronic unit is used to control the interrupter 24 as a function of the period data To, Tr, Tl. The unit 23 is provided with an input logic block 40 and a delay block 41. Input during the steady period To is ensured. This logic block 40 is connected to an oscillator 42. connected to provide a time pulse to ground conductor 26 and further input terminals 34 and 38; Furthermore, it is connected to the conducting wire 27 via an input terminal 43. Block 40.41 The output section is composed of three conductor wires 44 to 46, and these are for a period T, so of'! It is applied to counter 4 of J1 and counter 48 of 's2 for period T2. are connected to each other. Output block 49 excites interrupter 24 and provides an output lead. Apply appropriate voltage to line 540.

In the output block 49, the electronic lock is locked until an unlock signal is received via the conductor 46. Lock the output conductor 50. This output block 49 is further connected via a switch 52. It has an input terminal 51 connected to the conductor 27, and this switch is an IjlE switch. Although it is a touch sensor, it may also be a touch sensor.

FIG. 5 shows the state of the signal processed in the device of the invention, with time T On the horizontal axis, T-0 is the origin. The one shown at the top is the composite coded signal E. Then, the timing mechanism 13 causes the ammunition contact 6 and eventually the fuse terminal 21 to be detected. It is given to

This signal E has a continuous voltage charging signal 60, which is connected to the capacitor CI, By charging C2, the energy required for Need 5 is transferred. coding Signal 61 is preferably a pulse signal representing a digital code. 2 pals The timing signals 62, 62 represent periods T, , T+1, respectively, and the manual setting of the timing mechanism 13. It constitutes a series of pulses defined by the rector 15, 160 positions. write The fuse receives the energy and time data from the same signal at the same time. so only two contacts are required on the ammunition and no generator is required. It is.

In the logic block 40, the digital code of the coded signal 61 received at the input terminal 34 is processed. The code is compared with the stored corresponding code as described below. Two codes match If not, logic block 40 immediately connects the capacitor by grounding terminal 38. -Discharge C1 and C2. In this case, the fuse is required to ignite fuse 25. It has no energy.

If the codes match, logic block 40 changes the state of lock signal Sv on conductor 46. Connect this to output block 49 and open the electronic lock to create this block. be able to move. The number of pulses (T+) of the signal 62 is sent to the counter 47 and the signal 63 That (T*) is stored in the counter 48, respectively.

When the ammunition enters the first cartridge, it is in use! The S-preparation mechanism is energized and the switch 28 is closed. The origin T-0 of the same delay is determined. At this point, the signal on conductor 27 is connected to the capacitor. The value H is equal to the voltage of the circuit 02. In block 40.41, the capacitor Initialized (safety mechanism delay T0) and the point where the fuse 25 is still normal When a fire cannot be started, the terminal 38 is turned off after a relatively long time due to the conventional delay. Discharge the capacitor via.

When the period T0 has elapsed, the υ/D count control signal changes the state of the conductor 44 to The counter 4f, 48 and the output block 49 are excited. *The lead wire 45 is an oscillator A count signal fc based on 420 hour pulses is transmitted to two counters. No. The second counter 47 counts pulses corresponding to T. -48 is locked. Then, when receiving the excitation signal S1, this becomes the output block. It is transmitted to the block 49.

When the ammunition is impacted, from this point on the output block 49 opens the interrupter 24 and Close the switch 52 and apply the signal to the terminal 51. Output block 49 has period T2 Nakakono signal K.

ignition is controlled by That is, this means that the signal Sl is in the H state and the second counter This is when the signal S2 from the controller 48 is in the L state. Signal as shown in Figure 5 If the interrupter 24 happens to close due to the influence of the fuse 25, a high current! is common It causes the ignition 9゛.

If there was no shock, the signal S3 from counter 48 would be at the end of period T2. becomes H. Then, the output block 49 applies voltage to the conductor 50 to conduct the interrupter 24. This causes the fuse 25 to ignite. Thus the tie set by the timer The explosion occurs precisely at the moment of the explosion.

An example of the decoding mechanism 70 is shown in FIG. 40. That is, the decoding block 71 has an input terminal on the one hand. 34 receives a signal E, which in particular includes a decoded signal 61, and on the other hand an oscillator 42. It receives a time signal f0 from . Based on these signals, the decoding block 71 A digital composite signal 72 representing the code is connected to the input line 74 of the AND element 75. The data is given to the memory 73. The other input line 76 of this AND element is memory ( ROM) 77, and this memory 77 stores the code introduced in the memory 73. A reference code is stored for comparison with the standard code.

When the codes match, the AND element 75 sends the H-state output signal 78 to the second amplifier. The other input line of this AND element 79 receives the time signal f0. It receives a signal 80 from a counter 81 which receives 4. This counter is a delay element This function allows comparison only after the code is input into the memory 73. Ru. When both signals are in the H state, the AND element 79 outputs the lock signal Sv in the H state. Open the electronic lock as described above.

Instead of using a ROM as the memory 77, an electronic program as shown by the broken line in the figure is used. A programmable memory (EFROM) may also be used. In this case memory 77 is controlled by program block 88 to cause time signal f to reach input terminal 34. Receive the arriving signal. Memory 77 is thus applied to the input contact of the fuse. can be programmed in response to specially coded signals. Configure like this By doing so, various fuses suitable for various uses can be adopted, and effective cords can be changed. It is also possible to leave the fuse blank and store the desired code immediately before use.

FIG. 7 shows an example of an electronic lock 82 that can be incorporated into the output block 49. It is. The AND element 83 on the input side is the counter 47 of the lock signal Sv and N2. receives the signal sl from. As a result, its output 84 is the code signal at the end of period TI. The state becomes H only when 61 is correct. Roughly OR element 85 is switch 5 2 and a signal S2 from the second counter 48.

Thus, at the end of period T2, the output 86 of the AND element 85 becomes H. state. The output of the electronic lock (conductor 50) is formed by an AND element 87, The input side of this AND element is connected to an AND element 83 and an OR element 85.

Therefore, until the signals SV, Sl, S2 or the signals Sv, St, K+ are in the H state, Then the output (lead 50) is not in the H state or ready to control the fuse ignition. be.

In the embodiment shown in FIG. 8, the composite signal E is transmitted from the timing mechanism 13 to the ammunition 2. Transmission is performed by a magnetic circuit instead of an electric circuit. The advantage of this configuration is the transmission Because it does not require contacts, it is resistant to moisture and ammunition contamination. Ru.

This magnetic circuit 90 includes a magnetic conductor 90a in the timing mechanism 13 and a convex surface 91 of the ammunition. and an auxiliary magnetic conductor 90b placed at the tip. Also a clock The structure 13 is arranged on the convex surface of the box to form a weakly magnetic connection 93 between both conductors 90a and 90b. do. Each conductor has a ring shape with a center diameter 94a, 94b around which the coil 95a195b is wound. It has outer poles 96a, 96b, which cause the ammunition 2 to rotate about its long axis. There's no need to.

As shown in FIG. connected. The composite signal transmitted by magnetic means is the same as signal E in Figure 5. The difference is that an alternating signal is used instead of the signal 60.

The basic advantages of the invention described above are that it uses relatively simple and low cost ammunition; Moreover, it can be continuously adjusted during use as it is memorized just before loading the firearm. The main point is that it can fire automatic weapons while still functioning as a weapon.

Moreover, since timing information can be transmitted using a simple device and is protected by a code, ammunition This makes it possible to prevent unexpected discharges caused by errors or electromagnetic disturbances. coding system Since the system limits the use of ammunition to specific firearms, it is difficult to use ammunition illegally. There is no.

Additionally, the device of this invention can be transported separately and the firearm itself can be modified. It can be easily loaded into a firearm without any trouble. Low cost military like bullets Since it is possible to measure time even with commercial firearms, the scope of use of such firearms expands, Unlike conventional firearms, which easily explode when hit, for example, if you encounter an overwhelmingly superior enemy, This makes it suitable for gunfire postures that should be adopted in the event of an attack. However, this is not the only delay. It is suitable for any firearm that uses ammunition.

In addition to the above description, various changes are possible; for example, the period TI may be set as a steady state. It can also be preset by an electrical register stored in the phase 5. What's going on again? The clock mechanism 13 may be provided with only one manual selector.
