Developments in aircraft require safety verification through flight testing for many hours with prototype design and production. The test evaluation step of performing flight tests was an important process that determines the success in the development of the system. In particular, safety development through flight tests in the armed flight test is important for the development of attack helicopters. In the development of attack helicopters, the evaluation period and cost related to the armed flight test are closely related to the required ammunition requirement. Therefore, this paper presents the amount of ammunition required for the military flight test between attack helicopter developments through an analysis of the AH-1 helicopter in a similar case and ADS-44-HDBK of military specification. The AH-1 can be used to calculate the ammunition demand by considering the exclusion of redundant firing tests and configuration differences. In the case of the machine gun-equipped configuration, approximately 10,500R was required, and approximately 324R was required in the case of a rocket-mounted configuration. In addition, if the armed integrated bench is used properly, it is expected to promote efficiently the flight test in the armed flight by identifying the possible risk factors with armed flight tests and excluding them.

This paper describes the design of the circuit card assembly to eliminate the communication error on a servo control unit installed in the automated resupply vehicle K56. K56 is a weapon system that automates the supply and loading of ammunition on the K-55A1 self-propelled artillery. As the core item responsible for ammunition movement control, the servo control unit is required to have good communication stability and reliability, but the conventional unit has recognized a problem that communication error intermittently occurs, resulting in an emergency stop phenomenon. We analyzed the communication signal of the servo control unit and identified the failure cause of the circuit card assembly to solve this problem. In addition, the signal interference in data/address line of the circuit card assembly was confirmed through analysis of the failure cause, and redesigned to avoid the interference, such as adjustment of the distance between communication lines and position change. Finally, the proposed cause analysis and redesign were verified through the component of servo control unit and attachment test on K56. We expected these study results to be used as reference for the design of other similar items.

This paper is the study of a design to eliminate the communication error that occurs between the main controller and the servo controller of the K56 ammunition-carrying armored vehicle. The K56 assists in the operation of the K-55A1 self-propelled gun by automating the supply and loading of ammunition. The CAN communication board of the ammunition carrier is a key-function product mounted inside the main controller and installed for communication with the servo controller. It was confirmed that an undefined error would occur intermittently in the existing CAN communication board, interrupting the operation of the ammunition supply system during the loading process. In this paper, in order to solve the problem, the cause of the failure is identified through analysis and a functional test of the communication signal between the main controller and the servo controller. The error was resolved by redesigning and improving the Read/Write algorithm. Finally, the proposed cause analysis and design effectiveness were verified through the CAN communication board single item test and a system equipment application test. It is expected that this study will serve as a reference for improving defense capabilities through improving the reliability of CAN communication boards and by improving the reliability of the overall electronic equipment using DPRAM.

종말유도포탄과 동등한 효과를 올리기 위해서는 센서신관부의 탄약에 의한 사격은 통상 약 3배의 탄두수를 필요로 한다. 그러나 탄가가 약 4분의 1-5분의 1로 싸기 때문에 포탄수의 증가가 비경제적이라기 보다 비용대 효과면에서 오히려 유리하게 된다는 것이다. 수년 전에는 센서신관부의 탄약개발이 국제적으로 유행되어, 서독에서는 Diehi사와 Rheinmetall사가 참가하여 HABICHT 및 ZEPL 계획이라고 하는 2개의 프로젝트가 추진되었다. 그 후 이것은 하나로 통합되어 SMArt 155(155미리 포용 센서신관부 포탄의 약어)가 되었다

21세기 첨단과학기술의 발전과 불특정 위협 그리고 세계적 무기체계 발전추세를 감안한 화포의 사거리 증가는 한계에 도달하고 화력운용개념 또한 정밀타격을 요구하고 있는 상황하에서, K9 신형 155밀리 자주포를 통하여 종심지역의 적 전차 및 인원표적을 공격하는 능력을 갖추며, 지능형 탄약을 개발할 수 있는 기반을 조성하고, 국내 독자적인 장거리 탄약개발기술을 확보했다는 측면에서 개발의의 및 성과가 매우 크다 하겠다. 따라서 한국의 지정학적인 전략적 요충지로서 항상 주변 강대국 위협에 대비하는 전투력을 구비하도록 방위산업체 주도의 무기개발이 일반화되어야 할 것이다.

탄약 비군사화 심포지엄에 참석하여 안전하고 환경친화적인 불용탄 처리관련 기술현황을 분석하고 실제 운영중인 일부시설을 견학할 수 있었다. 또한 이 기간중 DAC의 주선하에 태평양지역 국가들의 회의 참석자들과의 별도 화합으로 Demil 정보를 교환하였다. 이와 같은 미국의 노력은 이 지역의 Demil 기술 종주국으로서 지도자 역할을 자임하려는 노력이 역력하였다. 현재 미국의 비군사화 사업은 대 테러전이 계속 진행됨에 따라 예산지원 우선순위에서 낮아져 향후 1-2년간은 사업규모의 축소 또는 지연이 예산된다. 따라서 정부내의 타부서와의 기술협력을 모색하여 기술개발은 꾸준히 이루어 질 것이다.
