Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a ground flying object with a homing device equipped with a non-guided submunition.

[Conventional technology]

A conventional submunition-equipped ground flying object,
It merely sprayed submunitions, and the situation of the target group was confirmed by homing, and it was not possible to optimally adjust the submunition dispersion range according to the situation.

[Problems to be solved by the invention]

The above conventional ground flying object has the following problems to be solved.

That is, since the range of the submunition dispersion cannot be adjusted in accordance with the situation of the target group, particularly the size of the target, for a narrow target group, the dispersion range is relatively widened, so that not only the power cannot be exerted but also the number of wasted bullets increases. This is uneconomical, and the spraying range is too local for a wide target group, and the spraying purpose cannot be achieved.

[Means for solving the problem]

The present invention provides a homing device for grasping a situation such as a scale density of a target group, and a target group grasped by the homing device in a ground flying object with a homing device equipped with an unguided submunition as a means for solving the above problem. A means for adjusting the range of dispersal of a submunition according to the situation is provided.

[Action]

The present invention has the following effects because it is configured as described above. (1) The flying object first checks the status of the ground target group, especially the scale, using a homing device, and thereby adjusts the range of the submunition to be optimally distributed. To achieve.

(2) Further, the inertia error of the flying object is corrected by the homing guidance, thereby enabling a long range.

〔Example〕

One embodiment of the present invention will be described with reference to FIGS. In FIG. 1, a homing device 3 is provided at the tip of the flying object 1, and an inertia device serving as a reference for determining a flying route is mounted behind the homing device 3. Immediately after that, there is a so-called warhead and a large number of submunitions 4 are filled. As shown in FIG. 1 (b), the submunitions 4 are arranged along the shaft on the outer periphery of the inner airbag 6 which can be rapidly inflated by gas filling, and are also surrounded by the outside. A two-stage arrangement is provided with the outer airbag which can be rapidly inflated by gas filling and which is arranged on the outer periphery of the outer airbag.

In addition, the outer airbag 5 and the inner airbag 6
As shown in the schematic air supply circuit diagram of the figure, the outer upper airbag 5a, the outer lower airbag 5b, and the inner upper airbag 6a, respectively.
And an inner lower airbag 6b, into each of which the valves 7, 8, and 9 are opened in an appropriate combination so that the filling gas flows in from the air bond 10 and expands. The submunitions 4 are accelerated and scattered by the inflation speed of the airbags. At that time, in order to adjust the flying distance so as to be able to adapt to the range of dispersion of the submunition 4,
The outer upper airbag 5a and the inner upper airbag 6a are inflated quickly with high pressure on the high pressure side inside the air bond 10,
The outer lower airbag 5b and the inner lower airbag 6b are basically configured to gently inflate at a relatively low pressure and communicate with the lower pressure side in the air bond 10 so as to reduce the flying distance. However, for example, when the valve 7 is opened while the valve 8 in FIG. 2 is closed, only the upper side is opened. It has become.

Next, an example of use of the above embodiment, that is, an operation will be described.

One embodiment of the present invention configured as described above will be described with reference to FIGS.

When the flying object 1 approaches the expected target position, the homing device 3 acquires data on the status (position, scale, etc.) of the target group, and replaces it with the target group size 11 as shown in FIG. . The flying object 1 releases the submunition 4 in the following two cases while guiding homing.

(1) When the target group is dense (the target size 11 is small): The valves 7, 9 shown in FIG. 2 are opened. Then, as shown in FIGS. 3 (a) and (b), gas is simultaneously sent to all the inner upper airbags 6a and the inner lower airbags 6b,
The submunitions 4 are released all at once to reduce the scatter area. In addition,
FIG. 3 (b) is a diagram corresponding to FIG. 1 (b).

(2) When the target group is large (target size 11 is large):
The valves 7, 8 shown in FIG. 2 are opened. And (c) of FIG.
At point A, the outer upper airbag 5a and the outer lower airbag 5b
To discharge the submunition 4. Outside upper airbag 5a
Since the gas pressure of the upper side is higher than that of the outer lower airbag 5b, the upper submunition 4 flies far. These situations are shown in (e) corresponding to (b). In addition, the airbag on the inside at point B
The upper and lower gas pressures are sent to the lower airbag 6a and the inner lower airbag 6b in the same manner as in the case of the point A, so that the spray range of the submunition 4 is optimally widened. These situations are shown in (f).

In the above, the embodiment has been described with an example in which the air bond 10 having a different gas pressure is prepared in advance. For example, the discharge distance of the submunition 4 is adjusted by adjusting the opening of the valves 7, 8, 9 to adjust the gas flow rate. Of course, it is also possible to adjust the spraying range appropriately.

Since the present embodiment is configured as described above, the submunitions are emitted at a stroke to the dense target group, and are emitted with a relatively small scatter distance by the inner airbag, and are discharged to the wide target group. In addition to providing a time difference between the inflation of the outer airbag and the inner airbag, the flying distance between the upper and lower airbags can be changed to distribute the submunitions evenly over a wide area, making the target group wider, narrower and lighter and darker. It is possible to perform the spraying optimally in response.

〔The invention's effect〕

The present invention has the following effects because it is configured as described above.

(1) The submunition has a longer range.

(2) It is possible to spray submunitions according to the situation of the target group.
