Abstract

Airworthiness certification of military aircraft is a government's certification that it must have airworthiness and ability to demonstrate its requested function and performance. NATO released STANAG-4671 to establish the minimum airworthiness requirements for UAVs between 150kg and 20,000kg MTOW in 2009. Up to now, there are no clear airworthiness certification criteria and guideline for small UAV which is less than 150kg. STANAG-4671 is used for military UAV airworthiness certification in Korea as Other Airworthiness Certification Criteria. However, since STANAG-4671 requires the same Target Level of Safety without regard to MTOW, excessive Target Level of Safety or design requirements could be applied to relatively small-medium UAV. In this paper, classification and criteria of airworthiness certification for military UAV were investigated and a Target Level of Safety was analyzed based on MTOW using ground victim criteria.

군용항공기 감항인증은 감항성을 가지고 요구된 성능과 기능을 발휘할 수 있음에 대한 정부의 인증이다. 북대서양조약기구(NATO)는 최대이륙중량 150kg 이상의 군용무인기에 대한 감항인증 요구도인 STANAG-4671을 2009년에 배포하였다. 최근 150kg 미만의 소형무인기에 대한 감항인증 요구도인 STANAG-4703을 내부적으로 배포하여 검토 중에 있다. 우리나라는 국제적으로 통용되는 감항인증 기준인 STANAG-4671을 기타감항인증 기준으로 준용하여 군용무인기에 적용하고 있다. 하지만 STANAG-4671은 중량에 관계없이 동일한 목표안전수준을 요구하여 낮은 중량의 중 소형무인기에 대해서는 목표안전수준이나 설계 요구도가 과도하게 적용될 수 있다. 따라서 본 연구에서는 군용무인기 분류와 감항인증 기준을 분석하고, 지상피해 평가기법을 적용하여 최대이륙중량별 목표안전수준을 제시하였다.
