Abstract

As the current ground transportation system becomes saturated, there is a need to develop a roadable personal air vehicle (PAV). Therefore, researches for PAV development and operation system development are being actively carried out in various countries around the world. PAV, the next generation transportation system, is a new concept of personal transportation that combines ground transportation, air traffic, and IT industry. Also, the development of PAV can solve the saturation of traffic congestion and shorten the travel time dramatically. In this study, we analyzed the certification criteria of FAR Part 23, which is going to be revised, and analyzed the patents and folding mechanism of Terrafugia Transition and Aeromobil 3.0, which are the most advanced of roadable PAV. Also, we used $OpenVSP^{(R)}$ for the reverse configuration design of the existing Terafugia transition and Aeromobile 3.0. Aerodynamic analyses were performed for the reverse configuration design using the $XFR5^{(R)}$ program.

현재의 지상 수송 교통 체계가 포화상태에 이르러 그 대안으로 도로주행형 개인용 항공기(PAV; personal air vehicle) 개발의 필요성이 대두되고 있다. 이에 따라 세계 각국에서는 PAV 개발과 운용체계 개발을 위한 연구가 활발히 이루어지고 있다. 차세대 운송 수단인 PAV는 지상 교통, 항공 교통, IT산업을 융합시킨 신개념의 개인 운송수단이다. 또한 PAV의 개발은 교통체증의 포화를 해소시킬 수 있고 이동시간을 획기적으로 단축시킬 수 있을 것이다. 본 연구에서는 개정 예정인 FAR Part 23의 인증기준에 대해 분석하고 도로주행형 개인용 항공기 중 가장 앞선 테라푸지아 트렌지션과 에어로모빌 3.0의 특허와 접이방식에 대해 분석하였다. 또한. $OpenVSP^{(R)}$를 이용하여 기존의 테라푸지아사의 트렌지션과 에어로모빌 3.0에 대한 형상 역설계를 수행하였다. 역설계한 형상데이터를 사용하여 공력해석을 $XFR5^{(R)}$프로그램을 사용하여 수행하였다.
