Abstract: PURPOSE: A fragment for a cannon ball and a manufacturing method thereof are provided to ensure low air resistance and rapid scattering speed since the width of a fragment is smaller than the diameter of a ball-type fragment. CONSTITUTION: A fragment(100) for a cannon ball comprises a 14-surface body(110). The body comprises 24 apexes(121,131) and 36 edges(123,133). 8 corners of the reguarl hexahedron of the body are cut to 33-37% depth from the edge toward the center of the regular hexahedron from the apex of the corner to remove triangular pyramid-shaped sections.

Abstract: The present invention relates to a penetrating warhead. The penetrating warhead includes a body unit in which gunpowder is loaded; a head unit formed in a cone shape on the upper end of the body unit; and a bottom unit blocking the bottom of the body unit and in which a fuse for igniting the gunpowder is inserted. Two or more pairs of side discharge holes formed on the outer side of the body unit, which is away 80-90% from the head unit to the bottom unit, are formed to face each other. As the side discharge hole is formed on the side of the warhead, internal pressure is discharged to the outside through the side discharge hole.

Abstract: 포탄용파편및 그제조방법을개시한다. 본발명의일 실시예에따른포탄용파편은 24개의꼭짓점과 36개의모서리를갖는 14면체형상의몸체또는 32개의꼭짓점과 48개의모서리를갖는 18면체형상의몸체를갖는다. 따라서육면체의코너또는모서리가절단된형상에대응되는다각형의몸체를구비하여정육면체파편에대비하여 3배수이상의꼭짓점과모서리를가짐으로써볼형파편보다우수한관통성과낮은도탄발생률을가지고, 볼형파편과동일한무게에너비는볼형파편의직경보다작음으로인하여볼형파편및 정육면체파편보다낮은공기저항성을가져서비산속도가더 우수하며, 볼형파편또는정육면체파편과비교하여동일부피의포탄(파편조립체)을형성할경우파편밀도가증대되어포탄성능을향상시킬수 있다.
