초록

전술 표적에 대한 정보를 획득하기 위해 전투기에 탑재하는 EO/IR 정찰용 파드는 일반적으로 항공기 동체 하단에 장착 운영한다. 이러한 외부 장착물을 장착한 항공기는 외부 장착물 없이 비행하는 항공기에 비하여 복잡한 공력 및 관성력 특성을 갖기 때문에 개발 초기에 개발 위험요소를 사전에 식별하여 설계에 반영할 수 있는 시스템 성능 분석 도구가 필수적으로 필요하다. 본 연구에서는 고기동 환경에서 안정적으로 측정 데이터를 획득할 수 있는 파드를 개발하기 위해 필요한 모델링 및 시뮬레이션 도구 개발 방안을 제시하였다. 우선, 고기동 항공기에 탑재한 파드의 한계 운용조건을 도출하고, 한계 운용조건에 따른 탑재 파드의 공력 및 관성 하중을 분석하였으며, 탑재파드를 장착한 항공기의 임무 모사를 통한 비행데이터 생성 및 전송 시스템을 개발하였다.

The EO/IR targeting pod mounted on a fighter to acquire information about tactical targets is typically mounted and operated at the bottom of the aircraft fuselage. Since the aircraft equipped with such an external attachment has complexed aerodynamic and inertial characteristics compared to the aircraft flying without an external attachment, a method of system performance analyses is required to identify development risk factors in the early stages of development and reflect them in the design. In this study, a development plan was presented to provide the necessary modeling and simulation tools to develop a pod that can acquire measurement data stably in a highly maneuverable environment. The limiting operating conditions of the pods mounted on the highly maneuverable aircraft were derived, the aerodynamics and inertial loads of the mounted pods were analyzed according to the limiting operating conditions, and a flight data generation and transmission system were developed by simulating the mission of the aircraft equipped with the mounted pods.
