DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and these embodiments are examples and can be implemented in various different forms by those skilled in the art to which the present invention pertains, and thus are not limited to embodiments disclosed herein.

[0021] Referring to FIG. 1, a simultaneous ignition cluster laser device 1 is composed of a laser cluster 10 and a hollow modular charge 30.

[0022] The laser cluster 10 is composed of six first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 that are grouped in a circle, and each of the first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 radiates a high-power laser using a single spot laser beam.

[0023] The circular shape of the first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 is configured so that the first laser oscillator 11 and the fourth laser oscillator 14, the second laser oscillator 12 and the fifth laser oscillator 15, and the third laser oscillator 13 and the sixth laser oscillator 16 are each arranged at 180 in a polar coordinate system.

[0024] Therefore, when the first laser oscillator 11 is positioned at 0, the second laser oscillator 12 is positioned at 60, the third laser oscillator 13 is positioned at 120, the fourth laser oscillator 14 is positioned at 180, the fifth laser oscillator 15 is positioned at 240, and the sixth laser oscillator 16 is positioned at 300.

[0025] Therefore, a path of the laser beam is adjusted at an inlet of each of the first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 so that a laser may be radiated to inner diameter black powder coating parts of unit charges Nos. 1, 2, 3, 4, 5, and 631, 32, 33, 34, 35, and 36 that match the laser oscillators.

[0026] The hollow modular charge 30 is composed of six unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 that have a propellant 37, and each of the unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 is a hollow propelling charge having a charge inner diameter 38 drilled at a central portion thereof.

[0027] The unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 are arranged in series between the unit charge No. 1 31 and the unit charge No. 6 36 in the order of the unit charge No. 232, the unit charge No. 333, the unit charge No. 4 34, and the unit charge No. 535 to linearly align the charge inner diameters 38. In this case, the unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 may be named as unit charges Nos. 1 to 6.

[0028] In addition, each of the unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 includes a gunpowder coating part 39 on the propellant 37 in the charge inner diameter 38, and the gunpowder coating part 39 is formed using black gunpowder.

[0029] Therefore, the laser cluster 10 radiates a laser beam to the charge inner diameter 38 of the hollow modular charge 30, and the first laser oscillator 11 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 131, the second laser oscillator 12 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 232, the third laser oscillator 13 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 3 33, the fourth laser oscillator 14 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 434, the fifth laser oscillator 15 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 535, and the sixth laser oscillator 16 radiates a laser beam to a gunpowder coating part 39 of the unit charge No. 636.

[0030] Referring to the developed view of the charge inner diameter of FIG. 2, in the description that the laser cluster 10 radiates the inner diameter surface of the charge in the farthest direction, the farthest direction may be described in a state of increasing a 360 rotation region by 60.

[0031] That is, this is a method of radiating a laser beam by matching the laser oscillator with the unit charge by refracting the path of the laser beam in the first laser oscillator 11 positioned at 0 (e.g., a 12 oclock direction) to radiate the black gunpowder coating part at a 180 position (e.g., a 6 oclock direction) of an inner diameter of the unit charge No. 131, refracting the path of the laser beam in the second laser oscillator 12 positioned at 60 (e.g., a 2 oclock direction) to radiate the black gunpowder coating part at a 240 position (e.g., a 8 oclock direction) of an inner diameter of the unit charge No. 232, refracting the path of the laser beam in the third laser oscillator 13 positioned at 120 (e.g., a 4 oclock direction) to radiate the black gunpowder coating part at a 300 position (e.g., a 10 oclock direction) of an inner diameter of the unit charge No. 3 33, refracting the path of the laser beam in the fourth laser oscillator 14 positioned at 180 (e.g., a 6 oclock direction) to radiate the black gunpowder coating part at a 0 position (e.g., a 12 oclock direction) of an inner diameter of the unit charge No. 434, refracting the path of the laser beam in the fifth laser oscillator 15 positioned at 240 (e.g., a 8 oclock direction) to radiate the black gunpowder coating part at a 60 position (e.g., a 2 oclock direction) of an inner diameter of the unit charge No. 535, and refracting the path of the laser beam in the sixth laser oscillator 16 positioned at 300 (e.g., a 10 oclock direction) to radiate the black gunpowder coating part at a 180 position (e.g., a 6 oclock direction) of an inner diameter of the unit charge No. 636 among the first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16.

[0032] This is to maximize the intensity of the laser beam radiated per unit area (i.e., minimize a reduction in intensity).

[0033] Meanwhile, the simultaneous ignition method for the hollow modular charge 30 using the cluster laser 10 includes positioning the laser cluster 10 for oscillating a laser beam at an inlet of the charge inner diameter 38 of the hollow modular charge 30 and radiating a laser from the laser cluster 10 in a direction that is close to the inlet of the charge inner diameter 38 and igniting the gunpowder coating part 39 positioned at the inlet side of the charge inner diameter 38. In this case, the gunpowder coating part 39 is black gunpowder coated on a surface of the propellant inside the charge inner diameter.

[0034] In addition, the simultaneous ignition method for the hollow modular charge 30 using the cluster laser 10 includes positioning the first laser oscillator 11 among the plurality of first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 forming a circular shape at an inlet of the unit charge No.1 31 among the plurality of unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 arranged linearly and radiating a laser from the first laser oscillator 11 to the charge inner diameter 38 of the unit charge No. 1 31 and igniting the gunpowder coating part 39 of the unit charge No. 1 31.

[0035] In particular, when the position of the first laser oscillator facing the unit charge No. 1 is 0, the laser radiation direction is matched in the order of the second laser oscillator and the unit charge No. 2, the third laser oscillator and the unit charge No. 3, the fourth laser oscillator and the unit charge No. 4, the fifth laser oscillator and the unit charge No. 5, and the sixth laser oscillator and the unit charge No. 6 for every 60 increase.

[0036] As described above, the simultaneous ignition method for the hollow modular charge using the cluster laser according to the present embodiment can maximize the intensity of the laser beam per unit area radiated to the gunpowder coating part 39 by adjusting the path of the laser beam from the first, second, third, fourth, fifth, and sixth laser oscillators 11, 12, 13, 14, 15, and 16 igniting the gunpowder coating parts 39 through one-to-one matching with the unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36 having the charge inner diameter 38 as they goes away due to the linear arrangement of the unit charges Nos. 1, 2, 3, 4, 5, and 6 31, 32, 33, 34, 35, and 36, thereby simultaneously igniting the plurality of lasers in a cluster-shaped combination.

[0037] The simultaneous ignition method for the hollow modular charge using the cluster laser according to the present invention can simultaneously ignite all of the plurality of hollow propelling charges, thereby minimizing ignition delay.
