MODE FOR INVENTION

[0060] Hereinafter, a cluster bomblet having a bomblet body for protecting a fuse according to the present invention will be described with reference to the accompanying drawings.

[0061] As illustrated in FIGS. 8 to 16, the cluster bomblet according to the present invention includes: a cylindrical bomblet body portion 10 packed with high explosives 11; a fuse assembly 20 including a striker screw 21 for igniting the high explosives 11 and being connected to a top side of the cylindrical bomblet body portion 10; a conical penetrator 15 provided inside a rear end portion of the cylindrical bomblet body portion 10; and an upper cover 30 sealing the top side of the cylindrical bomblet body portion 10, a connecting tube 33 connecting a fuse tube of the fuse assembly 20 and the connecting tube 33 being installed in the upper cover 30, and a stud 22 assembled to the fuse assembly 20 being inserted into the upper cover 30.

[0062] Here, the upper cover 30 may have an assembly surface portion 31 on which the fuse assembly 20 is seated and a side wall portion 32 extending upward from an edge of the assembly surface portion 31 to prevent the separation of the mounted fuse assembly 20. The assembly surface portion 31 has a connecting-tube mounting hole 31a in which the connecting tube 33 is disposed and a stud insertion hole 31b into which the stud 22 is inserted. The side wall portion 32 may extend to a lower side of the assembly surface portion 31.

[0063] The upper cover 30 may have an opening 34 formed in one side thereof, a slider 25 of the fuse assembly 20 being inserted into the opening 34. The cylindrical bomblet body portion 10 may have an opening 12 formed in an upper one side thereof and corresponding to the opening 34 of the upper cover 30. However, the opening 12 of the cylindrical bomblet body portion 10 may not be formed according to an insertion position of the upper cover 30.

[0064] A height, at which the upper cover 30 is connected to the cylindrical bomblet body portion 10, may be variable and may be appropriately adjusted as in FIG. 14.

[0065] That is, as illustrated in (a), the upper cover 30 may be deeply connected to the cylindrical bomblet body portion 10 such that the assembly surface portion 31 of the upper cover 30 is disposed at a height lower than that of an upper end of the cylindrical bomblet body portion 10. As illustrated in (b), the upper cover 30 may be connected to the cylindrical bomblet body portion 10 such that the assembly surface portion 31 of the upper cover 30 is disposed at a height equal to that of the upper end of the cylindrical bomblet body portion 10. As illustrated in (c), the upper cover 30 may be connected to the cylindrical bomblet body portion 10 such that the assembly surface portion 31 of the upper cover 30 is disposed at a height higher than that of the upper end of the cylindrical bomblet body portion 10. In this case, the respective connection conditions are selected depending on exterior exposure environments of a bomblet and a fuse according to characteristics of a mother bomb or depending on requirements, such as an amount of filled powder according to requirement performance of the bomblet. In addition, in the cases of (b) and (c), since the assembly surface portion 31 of the upper cover 30 is disposed at a height equal to or higher that of the upper end of the cylindrical bomblet body portion 10, the opening 12 of the cylindrical bomblet body portion 10 does not need to be formed.

[0066] As illustrated in FIG. 15, in a process of stacking and loading the cluster bomblets into a cluster bomb (mother bomb), since the fuse assembly 20 of an adjacent cluster bomblet is inserted into the conical penetrator 15 of an upper cluster bomblet and a portion of the side wall portion 32 of the upper cover 30 of the adjacent cluster bomblet is inserted through a lower end of the cylindrical bomblet body portion 10 of the upper cluster bomblet, the cluster bomblets according to the present invention are firmly stacked.

[0067] As illustrated in FIG. 16, the side wall portion 32 of the upper cover 30 may at least extend to a height higher than that of the slider 25 of the fuse assembly 20 of the upper cluster bomblet and may extend to a position of an end of the penetrator of the upper cluster bomblet. Due to the aforementioned structure, the fuse assembly 20 is firmly disposed inside of the upper cover 30. In addition, when the cluster bomblets are stacked, the reliability of a staking state is further improved by deeply inserting the side wall portion 32 of the upper cover 30 through the lower end of the cylindrical bomblet body portion 10 of the upper cluster bomblet.

[0068] Meanwhile, the upper cover 30 may be formed separately from the cylindrical bomblet body portion 10, and the upper cover 30 and the cylindrical bomblet body portion 10 may be integrally formed as illustrated in FIG. 13. In this case, the openings 34 and 12 are formed in the upper cover 30 and the cylindrical bomblet body portion 10, respectively.

[0069] The technical idea of the present invention has been described with reference to specific embodiments. In addition, there may be simple variations or simple expansion examples not included in embodiments described in the present specification, but the technical idea of the present invention should be construed on the basis of the appended claims rather than a technical interpretation category of embodiments.
