Abstract

The propulsion technology used in unmanned Aerial Vehicles (UAVs)—which represent one of the most important development directions in aviation—is significantly related to their flight performance. This review paper discusses the different types of propulsion technologies used in unmanned aerial vehicles, namely the internal combustion engine (reciprocating, rotary, and gas turbine engines), the hybrid system, and the pure electric system. In particular, this paper presents and discusses the classification, working principles, characteristics, and critical technologies of these types of propulsion systems. These findings are expected to be helpful in establishing a development framework, comprehensive views, and multiple comparisons of future UAV propulsion systems.

무인기에 적용되는 다양한 추진기관 기술은 항공의 중요한 개발 방향 중의 하나인 무인기의 비행 성능에 크게 관련이 있다. 본 논문에서는 무인기의 내연기관(왕복엔진, 로타리엔진, 가스터빈엔진), 하이브리드 및 순수한 전기 추진시스템에 대하여 조사를 수행하였다. 특히 이러한 추진기관들의 분류, 작동사이클, 특성 및 주요 기술들에 대하여 제시하였다. 그러므로 미래의 무인기 추진시스템의 개발 틀, 종합적인 예측 및 다양한 비교를 정립하는데 도움을 줄 것으로 판단된다.
