Abstract

Surion is required to install radios (U/VHF-AM, VHF-FM) capable of omni-directional communication. Therefore, this paper demonstrates the antenna performance test for the installation of the Surion communication antenna and the selection of optimal location. A simulation pattern analysis was performed employing the antenna, and a coupling test was performed by creating a new evaluation criterion. In addition, the results of the pattern flight test conducted at the previously suggested 1:20 turn and separation distance ratio were observed to be normal. However, the occurrence of voice cutoff was noted in the long-distance flight test. Therefore, in this paper, 1:300 (15 NM) is proposed as a new optimal ratio for predicting the long-distance flight test results in advance. Finally, the effectiveness of the proposed evaluation criteria was verified through long-distance flight tests. Consequently, it is expected to reduce the development schedule and cost by reducing the trial and error of the performance test for the Surion model. Also, the results of this study are expected to be used as standards for the installation of communication antenna and quality tests for other helicopters.

수리온은 전 방위 통신이 가능한 무전기(U/VHF-AM, VHF-FM) 장착 요구도가 있다. 이에 본 논문에서는 수리온 통신안테나 장착 및 최적위치 선정을 위한 안테나 성능시험에 관하여 다루었다. 안테나에 대한 시뮬레이션 패턴분석을 하였으며 새로운 평가기준을 만들어 커플링시험을 수행하였다. 또한 기존에 제시된 1:20의 Turn과 이격거리 비율에서 실시한 패턴비행시험 결과는 정상이었으나 장거리 비행시험에서 음성끊김 현상이 발생하였다. 이에 본 논문에서는 장거리 비행시험 결과를 사전 예측할 수 있는 최적의 비율로 1:300(15 NM)을 새롭게 제시하였다. 최종적으로 장거리 비행시험을 통하여 제시한 평가기준들의 유효성을 입증하였다. 본 연구의 결과로 수리온 기종에 대한 성능시험의 시행착오를 줄여 개발 일정단축 및 비용 절감을 예상한다. 또한 본 연구의 결과는 다른 헬리콥터 기종에 대한 통신 안테나 장착 및 품질 시험의 기준으로 사용 할 수 있을 것으로 기대된다.
