Description

Speed counting fuse for aerial bombs {TURNS-COUNTING FUZE FOR AIR BURST MUNITION}

The present invention relates to an air explosive bomb that maximizes the killing effect by air exploding in front of a target or on top of a concealed target in order to effectively attack enemies hidden in trenches, firewalls, or inside a building in ammunition for personal and public firearms. .

In general, mechanical and chemical fuses in ammunition are classified into impact functions that explode and collide with explosives and time functions that explode by a set time. These mechanical / chemical fuses are robust and simple in structure, but have limitations in terms of their ability to effectively kill enemies hidden in concealment and cover.

On the other hand, electronic fuses have a proximity function using radio waves, including the functions of mechanical / chemical fuses, and can combine various functions such as self-destructive function for safety and impact delay function that explodes after penetration. These electronic fuses are compact and have the advantage of combining a variety of functions. However, there are limitations such as securing a small special power supply device suitable for the purpose and securing reliability in a harsh environment.

Conventional rifle bullets and impact bombs do not have a killing effect on concealment / covering, and the electronic melee coal is difficult to apply to a personalizer on a small screen and is not suitable for a personalization machine. Therefore, in order to reinforce it, a new concept of ammunition that can be applied to personal devices and suitable for personalization is required.

Developed by this necessity is an explosive bomb. At this time, the electronic fuse for aerial bombs, the distance to the target is measured by a laser range finder and the time corresponding to the distance is input to the fuse from the fire control device is used for the shots fired. The shots are measured in real time during flight and explode in the air as soon as the fuse reaches the set distance.

In order to measure a real-time flight distance, an explosive bomb has a time-loading method of measuring a flight time. 1 is a block diagram of a conventional fire control apparatus and an electronic fuse for a time-loaded air explosive bomb. In the fire control device 10, the microprocessor 13 synthesizes a signal generated from the target distance input from the shooter with the power supply and sends it to the fuse charging device 19. The fuse 20 separates the power supply and the target distance signal through the fuse inserting device 19, charges the power to the power charging circuit, calculates a clock according to the target distance in the clock circuit 25, and reaches the corresponding clock. The detonation occurs when the detonation circuit 28 outputs the detonation signal.

However, this method is a method of automatically charging the flight time corresponding to the target distance from the communication device in the conventional time-fuse fuse, the correction function according to the change in the barrel bullet speed is possible to explode at the correct distance. In other words, since the shot of the barrel leaves the barrel, the speed of the shot must be measured and the corrected value must be input to the shot. Therefore, the structure becomes complicated and the production cost increases greatly.

The present invention solves the problems of the prior art as described above, and replaces the conventional time input method with a value corresponding to the distance to the target, and at a precise distance without complicated speed measurement and correction. The purpose is to provide a fuse that explodes.

Another object of the present invention is to provide a fuse for a revolution-loading aerial explosive bomb that can reduce the development and production costs of firearms and ammunition.

When the output value of the counter and the set explosion condition match by the comparison, the pulse generator 150 is stopped to complete the explosion condition signal. And transmitted to the fuse as the target flight speed.

Figure 2 is a block diagram of the firing control device and the electronic fuse of the rotating-load-type air-bombs according to the present invention.

Further, between the fire control device 100 and the electronic fuse 200, there is a fuse loading device 190 for charging the synthesized signal to the electronic fuse.

The electronic fuse 200 includes an external input blocking circuit 210 for blocking external input when signal transmission is completed; A power / signal separation circuit 220 separating the power and pulse signals; A power charging circuit 230 for charging the separated power; Electron fuse power 240 for storing the charged power; An electronic fuse memory / determination device 250 for storing the separated pulse signal, counting the number of revolutions of the bullet in flight, and determining an explosion condition; A rotation sensor 260 for detecting a rotation speed of the flying bomb; A detonator circuit 280 for receiving the signal and operating the detonator when an explosion signal of the memory judging device is satisfied; Electronic safety loading device 270 to secure a safety distance; It consists of an electric detonator 290 to detonate the explosives.

Hereinafter, the operation according to the configuration of the present invention will be described in detail with reference to FIG. 2.

First, in the fire control apparatus 100, the distance to the target measured by the laser range finder 110 mounted to the gun is input to the microprocessor 130, and the explosion type and the firing condition set by the external input device 120 are set. Input to the microprocessor 130. The microprocessor 130 calculates the explosive condition that combines the explosive distance converted into the rotational speed and the explosive form in consideration of the shooting condition into binary and inputs it to the comparator 140. The explosion condition signal is generated by combining the explosion conditions waited by the pulse generator 150 and the comparator 140.

Then, the power signal and the explosion condition signal of the power generator 170 are synthesized by the power / signal combining circuit 180 and supplied to the electronic fuse 200 through the fuse charging device 190 attached to the gun. Load the condition signal at the same time.

On the other hand, when charging of the power and the rotation is completed, the external input blocking circuit 210 operates to block external noise. The input power and the rotation speed are separated through the power / signal separation circuit 220. At this time, the power is stored in the electronic fuse power source 240 through the power charging circuit 230, the explosion condition signal is stored in the memory / judging device (250).

When the memory is completed in the memory / determination device 250, the bomb is automatically fired by sending the detonation signal toward the detonator circuit 280. Immediately after the shot is fired, the rotation speed detection sensor 260 detects the magnetic rotation speed of the shot during flight and inputs it to the memory / determination device 250. When the magnetic rotation speed of the shot reaches the set rotation speed, the detonation circuit The electric detonator 290 operates through 280 to explode air.

An electronic safety loader 270 is provided between the output of the memory / determination device 250 and the detonator circuit 280 to secure a safety distance. This is to prevent the risk that the external signal is generated in the memory / determination device 250 and the other circuits, so that a wrong signal is input and explodes within a safety distance. The electronic safety loader 270 refers to a circuit that limits the detonation signal so that it does not explode before leaving the safety distance from the launching point in order to secure a safety distance when the bullet is fired. The detonation signal from the memory / determination device 250 to the detonation circuit 280 passes only when the rotational speed is satisfied. At this time, the flight time is counted by an electronic timer, and the cumulative number of revolutions is counted by a rotation sensor.

In addition, when the shock is detected after the safety switch is out of the impact switch 300, the electric detonator 290 operates through the detonator circuit 280 to explode.

On the other hand, when the detonator is not operated even after the effective explosive distance is far enough after shooting, the memory circuit / determination device 250 may be initialized by disabling the reset circuit 310 in consideration of safety, and the explosion function may be disabled. .

As mentioned above, although this invention was demonstrated with reference to the Example and drawing, this is for the convenience of understanding of this invention, The scope of the present invention is not limited to this. Even if the reduction, addition and change of some components of the present invention are carried out, it cannot be denied that they belong to the right of the present invention as long as the scope of the present invention is defined by the appended claims.

As described above, the air-explosive-rotation-speed modulus electronic fuse according to the present invention has the effect of killing not only the exposed but also concealed / hidden enemy when the air-explosive effect at the correct setting distance is exposed to the rifle and impact bomb. It's very high and very effective in street fighting, making it possible to provide ammunition that gives you an edge over the battlefield. In addition, since the rotation speed charging type, there is no muzzle speed correction device compared to the time setting type, the gun can be simplified, the weight and manufacturing cost of the gun can be reduced, and the reduction of the rotation speed and the reduction of the bullet speed complement each other. By acting, the explosive distance is accurate in the atmosphere of atmospheric pressure change and rainy weather.
