초록

전 세계의 많은 대도시는 도시화에 따른 지상 및 지하 교통망이 포화되고 있다. 또한 지구온난화 방지를 위한 탄소배출 규제가 더욱 엄격해지고 있으며 이러한 문제의 해결책으로 복잡한 도심에서도 운행 가능한 eVTOL이 차세대 친환경 교통수단으로 각광받고 있다. 본 연구에서는 eVTOL을 멀티콥터형, 양력+순항형, 추력편향형으로 분류하여 각 유형별 eVTOL들의 호버 효율과 회전판 하중을 계산하였으며 공력해석 프로그램인 OpenVSP, Fluent와 JavaProp을 이용하여 각국의 감항당국 및 우버 사에서 발표한 보고서를 바탕으로 가까운 미래에 실현될 eVTOL의 원활한 운행에 필요한 배터리 비에너지를 계산하고 분석하였다.

In many metropolitan cities around the world, ground and underground transportation networks are saturated due to urbanization. In addition, regulations on carbon emissions to prevent global warming are becoming stricter, and eVTOL, which will be operating in complex cities, is gaining popularity as the next generation of eco-friendly transportation. In this study, the hover lift efficiency and disc loading of eVTOLs for each type were calculated by classifying eVTOLs into following types: multicopter, lift+cruise, and vectored thrust. In addition, using the aerodynamic analysis programs OpenVSP, Fluent and Javaprop, the specific battery energy required for the smooth operation of eVTOL, which will be realized in the near future, was calculated and analyzed base on reports published by Uber and airworthiness authorities of each country.
