Description

이중성형작약탄두 수직 정치 관통 시험용 치구 {Vertical setup tester for penetration test of double shaped charge}Jig for vertical stationary penetration test of double shaped charge warhead {Vertical setup tester for penetration test of double shaped charge}

본 발명은 시험 정확성 확보와 비용 절감 효과가 둘 다 얻어질 수 있는 이중성형작약탄두 수직 정치 관통 시험용 치구에 관한 것이다.The present invention relates to a fixture for vertical stationary penetration testing of a dual-shaped peony warhead that can both secure test accuracy and reduce costs.

이중성형작약탄두는, 전차의 반응장갑(판)으로 인해 탄두의 위력이 감소하는 것을 극복하기 위하여 개발된 것으로서, 선구탄두와 주탄두가 직렬로 배치된 이중 탄두로 구성되어 있으며, 선구탄두가 먼저 폭발하여 반응장갑(판)을 무력화하고, 뒤이어 주탄두가 폭발하여 주장갑(판)을 무력화(관통)한다.The dual shaped charge warhead was developed to overcome the reduction in power of the warhead due to the tank's reactive armor (plate). It consists of a dual warhead with a precursor warhead and a main warhead arranged in series, with the precursor warhead coming first. It explodes to neutralize the reactive armor (plate), and then the main warhead explodes to neutralize (penetrate) the main armor (plate).

이중성형작약탄두의 위력을 확인하기 위한 방법으로서, 종래에는, 고온의 메탈제트가 수평방향으로 형성되는 수평 정치 관통 시험이 행해졌다.As a method for confirming the power of a double star warhead, a horizontal stationary penetration test was conventionally performed in which a high-temperature metal jet was formed in the horizontal direction.

종래의 수평 정치 관통 시험은 시편받침대 위에 수평방향으로 정렬시킨 다수의 시편(주장갑의 대용품) 중 제일 앞쪽에 놓여 있는 시편 앞에 반응장갑을 배치하고, 탄두받침대 위에는 이중성형작약탄두(시험 탄두)를 설치한 후, 탄두를 연쇄 폭발시키는 방식으로 진행되었다.In the conventional horizontal stationary penetration test, reactive armor is placed in front of the specimen placed at the front of a plurality of specimens (substitutes for main armor) arranged horizontally on a specimen holder, and a double-shaped charge warhead (test warhead) is placed on the warhead holder. After installation, the warheads were exploded serially.

이러한 수평 정치 관통 시험은 시편받침대 및 탄두받침대 등과 같은 시험 기자재의 제작에 비용과 시간이 많이 들고, 시편받침대 위에 수평으로 정렬하는 시편끼리의 사이에 틈이 생기기 쉬워 정확한 시험을 행하기 어려운 단점이 있다.This horizontal stationary penetration test requires a lot of cost and time to manufacture test equipment such as a specimen stand and a warhead stand, and has the disadvantage of making it difficult to perform an accurate test because gaps are easily formed between specimens aligned horizontally on the specimen stand. .

한편, 본 발명과 동일·유사한 기술이 있는지 조사해 보았지만, 고온의 메탈제트가 수직방향으로 형성되도록 하는 관통 시험에 관한 선행기술문헌은 찾아내지 못했다. 다만, 방위 분야에서 행해지는 탄두 관련 시험의 대부분은, 특허문헌 1∼3에 개시된 바와 같이, 시험에 관련된 기자재와 시험 대상이 수평방향으로 정렬되어 행해지는 수평 시험인 것을 재차 확인할 수 있었다.Meanwhile, although we investigated whether there was a technology identical or similar to the present invention, we could not find any prior art literature regarding a penetration test that causes a high-temperature metal jet to be formed in the vertical direction. However, it was confirmed again that most of the warhead-related tests conducted in the defense field are horizontal tests in which the equipment and test objects related to the test are aligned in the horizontal direction, as disclosed in Patent Documents 1 to 3.

본 발명은 종래 수평 정치 시험에서의 단점을 해결하기 위한 것으로서, 시험 기자재의 제작에 소요되는 비용과 시간을 줄이고, 실제 운용 환경과 유사한 환경하에서 시험이 실행됨으로써 시험의 신뢰성·정확성을 확보할 수 있도록 하는 이중성형작약탄두 수직 정치 관통 시험용 치구를 제공하는 것에 목적이 있다.The present invention is intended to solve the shortcomings of the conventional horizontal stationary test, to reduce the cost and time required to manufacture test equipment, and to ensure reliability and accuracy of the test by performing the test in an environment similar to the actual operating environment. The purpose is to provide a fixture for testing vertical stationary penetration of a dual-shaped peony warhead.

상기 과제를 해결하기 위해, 본 발명에 따른 이중성형작약탄두 수직 정치 관통 시험용 치구는, 시험 탄두(이중성형작약탄두)와 시편 적층체를 수직방향으로 소정(설정) 거리만큼 이격시켜 정렬할 수 있고, 첫 번째(최상층) 시편 위에 배치하는 반응장갑(또는 대용품)의 설치각도를 조정 가능하게 구성한 것을 특징으로 한다.In order to solve the above problem, the fixture for vertical stationary penetration test of a dual-shaped peony warhead according to the present invention can align the test warhead (double-shaped peony warhead) and the specimen stack by spaced apart by a predetermined (set) distance in the vertical direction. , It is characterized by an adjustable installation angle of the reactive armor (or substitute) placed on the first (top layer) specimen.

후술하는 실시형태에서, 본 발명의 이중성형작약탄두 수직 정치 관통 시험용 치구는, 테두리만 남기고 모든 면이 개구(開口)된 육면체 구조의 받침대와, 받침대의 하측 테두리 아래로 하단부가 돌출되는 형태로 받침대의 후측 테두리에 고정되는 후면판과, 받침대의 하측 테두리 아래로 하단부가 돌출되는 형태로 받침대의 전측 테두리에 고정되는 전면판과, 받침대의 상측 테두리에 지지되며 메탈제트가 통과 가능한 관통구멍이 중앙부분에 형성된 덮개와, 덮개의 관통구멍의 둘레에 지지되는 가이드링과, 반응장갑의 일측이 지지될 수 있도록 받침대의 전측 테두리의 하단측에 설치하거나 받침대의 하측 테두리의 전단측에 설치하는 고정대로 구성되어 있다.In an embodiment described later, the fixture for vertical stationary penetration test of a dual-shaped peony warhead of the present invention includes a base of a hexahedral structure with all surfaces open except for the edge, and a base with the lower end protruding below the lower edge of the base. The rear plate is fixed to the rear edge of the stand, the front plate is fixed to the front edge of the stand with the lower end protruding below the lower edge of the stand, and the center part is supported on the upper edge of the stand and has a through hole through which the metal jet can pass. It consists of a cover formed on the cover, a guide ring supported around the through hole of the cover, and a fixture installed on the lower side of the front edge of the stand or on the front end of the lower edge of the stand so that one side of the reactive armor can be supported. It is done.

본 발명에 따르면, 시편 적층체와 시험 탄두가 하나의 받침대에 의해 수직방향으로 정렬되므로 시험 기자재의 제작 비용이 종래보다 절감되는 효과가 있고, 다수의 시편이 수직방향으로 간극 없이 적층되어 실제(운용 환경)와 유사한 조건하에서 관통 시험이 진행되므로 정확한 시험 결과가 얻어지는 효과가 있다.According to the present invention, the specimen stack and the test warhead are aligned in the vertical direction by one stand, which has the effect of reducing the manufacturing cost of the test equipment compared to the conventional method, and multiple specimens are stacked in the vertical direction without gaps for actual (operational) use. Since the penetration test is conducted under conditions similar to the environment, accurate test results are obtained.
