Abstract

In this paper, we selected commuting scenarios in the most congested metropolitan area in Korea, and conducted noise analysis during personal air vehicle (PAV) operation using aviation environmental design tool (AEDT)software which was developed by Federal Aviation Administration (FAA). Noise is the second important factor after safety in order to operate PAVs through concepts such as ODM (on-demand mobility) introduced by National Aeronautics and Space Administration (NASA). Noise analysis were performed by modeling low-noise ePAVs as commercial helicopters and predicted residential suitability in order to resolve problems in which accurate NPD (noise power distance) data from PAVs were not released. The application of noise reduction technology such as electric propulsion has significantly reduced noise exposure levels and has reached the conclusion that commuting with PAVs is feasible without noise problems in the metropolitan area.

본 논문에서는 우리나라에서 가장 교통이 혼잡한 수도권에서의 출퇴근 시나리오를 선정하고, 미국연방항공국에서 개발한 AEDT (aviation environmental design tool) 소트프웨어를 사용하여 PAV (personal air vehicle) 운용 시 발생하는 소음분석을 수행하였다. 미항공우주국에서 선보인 ODM (on-demand mobility) 개념에서 PAV를 운용하기 위한 안전성 다음으로 소음이 중요한 고려요소이다. PAV의 정확한 NPD (noise power distance) 데이터가 공개되어 있지 않는 문제를 해결하고자 eVTOL (electric vertical take off and landing) PAV와 같은 저소음 PAV를 민간용 헬리콥터로 모델링하여 소음 분석을 수행하고, 해당지역의 주거 적합성을 예측하였다. 전기추진과 같은 소음 감소 기술의 적용은 소음 노출 레벨을큰 폭으로 감소시켰고, 수도권내에서 소음문제 없이 PAV를 이용한 출퇴근이 실현 가능하다는 결론에 도달하였다.
