초록

대한항공은 유인 헬리콥터를 무인화 후 원격 조종으로 제자리 비행을 수행하는 것을 무인 헬리콥터 개발의 1단계 목표로 수립하였다. 개발 목표를 달성하기 위해 대한항공은 유인기의 창급정비와 기체 개조 수행 후 체계통합, 지상시험, 안전줄 시험을 순차적으로 수행하며 단계별로 무인 헬리콥터 체계의 조종성과 비행안전성을 검증하였다. 특히 검증의 마지막 단계에서 사용한 안전줄시험 기법은 완전무인화된 무인 헬리콥터 체계에 대해 비행안전성과 조종성을 검증할 수 있는 유효한 방법임을 확인하였다.

Korean Air has set the goal of the first stage of the development of unmanned helicopters to perform in hovering flight by remote control. In order to achieve the development goal, Korean Air carried out system integration, ground test, and safety wire test in sequence after carrying out programmed depot maintenance and aircraft modification of manned aircraft, and verified the controllability and flight safety of the unmanned helicopter system step by step. In particular, it was confirmed that the safety wire test technique used in the final stage of verification was an effective method to verify flight safety and controllability for a fully unmanned helicopter system.
