Abstract

KARI (Korea Aerospace Research Institute) is developing a design framework for the concept and preliminary design of eVTOL aircrafts. A low fidelity mission analysis tool was developed for the eVTOL aircrafts of Lift-Tilt Concept, which have tilt propellers and lift propellers, using open source SUAVE package. For its development, a review for the propeller performance analysis functionality was made. To find the trim solution at each mission segment automatically, an algorithm is implemented, using a global optimization technique through parallel processings and DOE(design of experiment). Using the tool, the one seated eVTOL OPPAV(optionally piloted personal air vehicle) was modeled and evaluated, which results were compared with the preliminary design data.

항우연은 eVTOL 항공기의 개념설계 및 기본설계를 위한 설계프레임워크를 개발하고 있다. 오픈소스 SUAVE 패키지를 활용하여 틸트 프롭 및 리프트 프롭을 갖는 Lift-Tilt 개념의 전기수직이착륙기에 대한 저충실도 임무분석도구를 개발하였다. 그 개발을 위하여 SUAVE의 프롭성능해석 기능을 검토하였다. 매 임무 세그먼트에서 트림해를 자동적으로 찾기 위해 병렬처리 및 실험계획법을 통한 전역최적화 기법을 적용한 알고리듬을 구현하였다. 동 도구를 사용하여 1인승급 전기추진 수직이착륙 유무인 겸용 개인항공기(OPPAV)의 임무분석을 수행하고 동 항공기의 기본설계데이터와 비교하였다.
