윤흥수,류연승 한국융합학회 2018 한국융합학회논문지 Vol.9 No.7

상용차량 확대계획 및 군수품 상용화 정책에 의해 군용차량은 민간차량의 플랫폼을 사용하여 개발되고 있다. 그러나 민간차량의 플랫폼 정보가 정비지침서, 전장회로도 등에 담겨 공개되고 있기 때문에 민간차량과 동일한 플랫폼을 사용하는 군용차량도 관련 정보가 노출될 수밖에 없다. 특히 군용차량에 미사일, 레이더 등을 탑재하면 전투 목적을 가진 혼성장비가 되므로 기술보호 적용을 검토하여 정보 유출을 차단해야한다. 혼성장비는 2가지 이상의 장비로 구성된 장비를 말하며, 주장비 부분과 보조장비 부분으로 구분된다. 본 연구에서는 국내 혼성장비 차량부 시험평가 제도 및 방위산업기술 보호체계의 문제점을 도출하고, 전문가 인터뷰를 통해 개선방안을 도출하는 방법으로 연구를 진행하였다. 개선방안으로 전력화 시점을 기준으로 당시 최신 배출가스 기준이 반영된 엔진을 탑재한다는 조항을 추가하여 민간법령과 육군규정의 혼선을 줄이고, 상용화로 된 군수품의 역할 및 기능을 고려하여 방위산업기술의 요소기술로 선정하였다. The military purpose vehicles are developed by using the platform of civil vehicles according to the commercial vehicle expansion plan and military supplied product commercialization policy. But the information related to the military purpose vehicle which adopts the same platform with the civil vehicle is forced to be exposed because its information is revealed by containing into the maintenance manual and electric circuit diagram. Especially, the information disclosure should be blocked by reviewing the application of technology protection because the military vehicle becomes combating purposed mixed equipment when the missile and radar are mounted. The mixed equipment means the one configured with more than 2 types of equipment, and it is categorized into the main and sub equipment. This study was performed to derive the problems in Korean system for vehicle part test evaluation on the mixed equipment and the defense industry technology protection system, and to derive the methods for improving through interviews with the specialists. The conflicts between the civil laws and army regulation were reduced by adding a clause that the engine reflected with the newest emission gas standard should be mounted based on the time of force integration, and the commercialized military supplies were designated as element technology of defense industry technology in consideration of its roles and functions.

군용차량 배출가스 규제 개선에 관한 융합적 고찰

윤흥수 한국융합학회 2020 한국융합학회논문지 Vol.11 No.1

Civil technologies and parts occupy big ratio in military vehicle as military supply goods were commercialized. In case of the military vehicle engine, the civil purposed engine has been militarized without developing engine for defense industry. Because of this, it happens that Euro-5 version is mounted in spite of Euro-6 at present because the civil laws on the civil purpose engine and required operational capability for militarization are applied by overlapping. Therefore, this study focused on current situation and issues on the military vehicle emission regulation and suggested how to improve through analyzing the theses, articles, Korean laws and systems. For improving methods, imposing the emission certification duty and exempting the certification for the vehicle of high strategical importance were suggested through aligning the related laws. Consequently, it is expected that this study will be used for basics of checking the civil laws and connection with military systems for commercialization of military supplied goods. 군용차량은 군수품 상용화에 의해 민수 기술 및 민수품의 비중이 크다. 군용차량 엔진의 경우 방산용 엔진을 개발하지 않고 민수용 엔진을 군용화 하고 있다. 이로 인해 민수용 엔진에 대한 민간 법령 및 군용화에 필요한 작전요구성능이 이중으로 적용되어 현재 유로-6임에도 불구하고 유로-5 버전이 탑재되는 현상이 발생한다. 이에 본 연구는 논문, 기사, 국내 법령 및 제도 등을 분석하여 군용차량 배출가스 규제의 현 실태 및 문제점을 고찰하고 개선방안을 제시하였다. 개선방안으로 관련 법령을 정비하여 배출가스 인증 의무를 부과하고 전략적 중요도가 높은 차량에 한해 인증을 면제하는 방안 등을 제시하였다. 이로써 향후 군수품 상용화에 따른 민간법령 및 군 제도의 연계성을 점검하는데 기초연구로 활용될 것으로 기대된다.
