Abstract

An aerial refueling provides for extension of operational time and range for aircraft and enhances mission effectiveness, hence it application by most military aircrafts. The receiver aircraft should have the aerial refueling clearance that is established by performing technical and operational compatibility assessments to certify it for aerial refueling with a specific tanker model. The compatibility assessment includes aerial refueling handling qualities, functional, fuel, lighting system testing and it is finally verified through flight testing. However, since aerial refueling compatibility assessments have never been performed in Korea, there is no experience to determine the test requirements and the scope and size of the test program for a new development aircraft. This paper therefore introduces the common techniques of aerial refueling and aerial refueling flight test methods to understand the aerial refueling FCS (Flight Control System), OFP (operational flight program) and system validation, and aerial refueling envelope clearance of a fixed wing aircraft for a boom and receptacle refueling system that is being introduced into Korea Air Force.

공중급유 능력은 항공기의 임무시간 증대와 운용영역 확장을 제공함에 따라 많은 군용기에 적용 및 운영되어왔다. 피급유기가 지정된 급유기로부터 공중급유를 받기 위해서는 기술 및 운용호환성평가를 통해 공중급유허용을 확보해야 한다. 적합성 평가에는 공중급유 조종성, 기능성, 연료, 조명시스템 평가를 포함하고 있으며 비행시험을 통해 최종 검증된다. 그러나 한국에서는 신규개발항공기에 대한 공중급유 적합성 평가를 수행한 사례가 없기 때문에 시험 요구도, 범위 및 프로그램 규모를 결정하기 위한 경험이 없는 상황이다. 본 논문에서는 공중급유 유형 소개와 한국 공군에 도입된 Boom & Receptacle 시스템에 대한 고정익 항공기 공중급유 FCS (Flight Control System) OFP (operational flight program) 검증, 시스템 검증 및 영역 허용 관련 공중급유 비행시험 방법을 연구하였다.
