Abstract

Contrail is type of clouds which are formed by a condensation of water vapour from the aircraft exhaust when the aircraft is flying the cold atmosphere. Since contrails have considerable effect on greenhouse-effect and military stealth efficiency, researches about contrail avoidance technology has been conducted for decades. However, none of the previous researches concerning contrail avoidance was carried out in Korea. Thus, review of the previous study regarding contrail reduction is absolutely needed. In this paper, researches conducted by several countries are categorically introduced, and practicabilities of their methods are analyzed. This paper also suggests some practical and systematized way to conduct future researches about contrail avoidance.

비행운은 항공기가 차가운 대기를 비행할 때 엔진 배기의 수증기가 응축하여 발생하는 구름을 말한다. 비행운은 지구 온난화의 원인중 하나로 지목되고 있으며 군사적으로는 항공기 스텔스 기술과 연관되어 있으므로, 이를 저감하기 위한 관련 연구가 진행되었다. 그러나 우리나라의 경우 관련 연구가 전혀 진행되지 않은 실정이므로, 연구 수행을 위한 기초자료로써 선진국의 비행운 저감 기술 사례를 집중적으로 분석할 필요가 있다. 본 논문에서는 선진국에서 수행되었던 비행운 저감 기술 동향을 카테고리 별로 파악하고, 제시된 각 기술들의 타당성과 실현 가능성을 분석하였다. 또한 관련 기술의 적용 및 상용화를 위한 방향을 제안하였다.
