Abstract

This paper addresses the installation and modification design of airframe structures for new and modified equipment installations that are essential for aircraft performance improvement. Typical performance improvement equipment mounted on the exterior of the aircraft include antenna, radar, electro-optical/infrared (EO/IR), and self-protection system equipment, which require structural reinforcement, modification, and mounting design of the green aircraft for operation. In the interior of the aircraft, console and rack structures are modified or added according to user operation requirements. In addition, this is accompanied by the installation design of equipment to be replaced and added for performance improvement, and the according modification of environmental control system components for internal cooling. The engineering process and cases in which airworthiness was verified through the detailed design of airframe structures with structural integrity, operability, and maintainability of performance-improved aircraft are presented.

본 논문은 항공기의 성능개량에 필수 수반되는 신규 및 변경 장비 장착부에 기체구조물 개조 및 장착설계를 수행한 연구이다. 항공기 외부에 장착되는 대표적인 성능개량 장비로는 안테나, 레이더, 전자광학/적외선 표적지시장치(EO/IR) 및 자체방어체계 장비 등이 있으며, 운용을 위해서 기본항공기의 구조보강, 개조 및 장착설계가 수행된다. 항공기 내부에는 사용자 운용 요구도에 맞게 콘솔과 랙 구조물이 개조 또는 추가된다. 또한 성능개량을 위해 교체 및 추가되는 장비의 장착설계와 이에 따른 내부 냉각을 위한 환경제어계통 구성품 개조가 수반된다. 성능개량 항공기의 구조건전성, 운용성 및 정비성이 확보된 기체구조물의 상세설계로 감항 적합성이 검증된 엔지니어링 과정과 사례를 제시하였다.
