Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention controls the firing speed of a gun by the difference between the target and the actual bullet landing position of a continuous firing gun such as a machine gun or rapid-fire gun, that is, the bullet landing error. To a launch command device.

The firing speed here refers to the number of bullets fired per minute, and is different from the bullet speed.

(Conventional technology) Conventionally, continuous firing guns with variable firing speeds have been used to visually check the landing error. If the landing error is large, the firing speed is slowed to correct the target, and the landing error is corrected And then adjusted to the maximum firing rate. Therefore, it is necessary to perform artificial operation depending on the battle situation, and a high degree of skill is required for this.

(Problems to be Solved by the Invention) A large amount of time and a large amount of materials such as ammunition are required for the above-mentioned advanced skill.

Also, in order to increase the shooting down rate, it is necessary to always fire the bullet at the maximum firing speed, but it is common that the impact error is large in the initial stage after the start of firing, and the probability of becoming an effective bullet is low,
It becomes an invalid bullet and cannot efficiently operate ammunition.

Further, when the firing speed is set to a low value in advance for the purpose of efficient ammunition operation, there is a problem that the shot spray cumulative density is reduced and the shooting down rate is reduced.

DISCLOSURE OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a gun firing speed varying device having high ammunition operating efficiency and a high shot down rate.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the firing command device of the continuous firing gun includes an impact detection circuit 4 that detects a relative positional relationship between the target 1 and the impact position 2. A gun firing speed variable circuit 5 for changing the firing speed, which is the number of bullets fired from the gun per minute, according to the gun landing error signal output from the gun landing detection circuit 4, and this gun fire speed variable circuit 5 And a gun firing command circuit 6 for controlling the firing speed of the gun in accordance with the firing speed command signal.

(Operation) As described above, a deviation (an impact error) between the target 1 and the actual impact position 2 is detected, and this error signal is input to the gun firing speed variable circuit 5 to set the preset " Since the function of “shooting error versus firing speed” is stored in the gun firing speed variable circuit 5, the firing speed is determined according to the firing error signal, and the firing speed is automatically adjusted.

(Embodiment) FIG. 1 is a functional block diagram of a gun firing speed varying device of the present invention. In the figure, 1 is a target to be attacked, and 2 is an impact position of a bullet fired at the target 1. In this case, the target 1 and the landing position 2 need to be within the detection visual field 3 of the landing detection circuit 4.

The deviation between the target 1 and the landing position 2 in the detection field 3 is output from the landing detection circuit 4 as a landing error signal, and the gun firing speed variable circuit 5 determines the firing speed by this output signal,
It is input to the gun firing command circuit 6 as a firing speed command signal.
Based on this input, the gun firing command circuit 6 outputs a firing command to a gun (not shown) to cause continuous firing.

Next, the control operation of this device will be described. FIG. 2 is an operation curve diagram. Based on this curve diagram, the gun firing speed variable circuit 5 stores a function of “shooting error versus firing speed” to be preset. Immediately after the launch is started, the hitting error is generally large, so the hitting error signal obtained by the hitting detection circuit 4 is also large, and the probability of being an effective bullet hitting the target 1 is low. During this period, the firing speed is lowered to suppress the consumption of the ammunition.
If the aim is corrected during this period, the effective shot probability is improved and the shot-off error is reduced. Therefore, the shot-off error signal becomes small, and the change in this signal causes the shot-speed command from the gun-fire speed varying circuit 5 to change. The signal also changes in the direction of increasing the firing speed, and the gun firing command circuit 6 raises the firing speed of the gun to the maximum firing speed.

In this way, the shot-off error signal is always sent to the gun firing speed variable circuit 5
By feeding back to, it is possible to change the firing rate, which is the number of bullets fired from the gun per minute. Therefore, it is possible to fire an effective ammunition number without impairing the shot-down rate.

(Effects of the Invention) As described above, the gun firing speed varying device of the present invention can automatically control the firing speed of the bullets according to the amount of the landing error between the target 1 and the landing position 2, and thus the shooting rate. Optimum firing control regarding the number of shot ammunition can be realized, and the number of shot ammunition can be saved.

Therefore, it can be used for various gun systems having a limited number of ammunition storage capacities.

This savings in the amount of ammunition fired can also improve the ability to continue combating engagements with multiple targets.
