Abstract

In this paper, the optimal placement of the rotary wing's communication and navigation antennas was evaluated by measuring their performance through ground simulations and flight tests. To select the mounting position of the communication and navigation antenna on the helicopter, after considering the shape and characteristics of the airframe, the radiation patterns, coupling analysis, equipment operation profiles, and antenna type analysis were performed for the aircraft-mounted antenna. Based on the analysis results, a procedure for sequentially performing voltage standing wave ratio (VSWR) measurement and antenna pattern test was established through ground and flight tests of the antenna. The systematic performance measurement method and procedure proposed in this paper were verified through ground and flight tests of the Light Armed Helicopter (LAH) system.

본 논문에서는 회전익 항공기 통신·항법 안테나의 최적 위치와 체계 성능측정 방법에 대해 연구하였다. 통신·항법 안테나의 항공기 최적 장착 위치 선정을 위해 기체 형상 및 특성을 고려한 후 항공기 장착 안테나에 대한 복사패턴, 커플링 분석, 장비 운용 프로파일 및 안테나 종류별 분석을 수행하고, 분석결과에 따라 항공기에 장착된 안테나에 대한 지상시험 및 비행시험을 통해 VSWR 측정, 안테나 패턴시험을 순차적으로 수행하는 절차를 정립하였다. 본 논문에서 제안한 체계적인 성능 측정 방법 및 절차는 LAH(소형무장헬기)체계의 지상 및 비행시험을 통해 입증하였다.
