Abstract

Companies around the world are actively developing Personal Air Vehicle (PAV) to solve the serious social problem of traffic jams. Airworthiness certification for PAV is required, since it is a manned vehicle. As with aircraft, the critical threat to the safe operation of PAV is lightning strike with strong thermal load and magnetic fields. Lightning certification issue also remains important for PAV, since there are still insufficient development of PAV-related lightning certification technologies, guidelines, and requirements. In this study, the SAE Aerospace Recommended Practice (ARP), an international standard certification guideline recognized by the Federal Aviation Administration (FAA), was analyzed. In addition, the guideline of lightning certification was applied to a PAV. The impact of lightning on PAV was also analyzed through computational software. Finally, the basis for the establishment of the PAV lightning certification guidance was presented.

세계 여러 기업에서는 교통체증이라는 심각한 사회 문제를 해결하기 위해 개인용 항공기 PAV(Personal Air Vehicle) 개발이 활발히 이루어지고 있다. PAV는 사람이 탑승하는 유인운송수단이므로 반드시 감항인증이 요구된다. 항공기와 마찬가지로 PAV의 안전 운항에서 치명적인 위협을 가하는 요소는 고온의 열과 자기장을 동반한 낙뢰이다. 현재 PAV 관련 낙뢰 인증 기술, 지침 및 요건 개발이 미비한 실정이기 때문에 PAV 낙뢰 인증은 더욱 중요하다. 본 연구에서는 미연방항공청(FAA)에서 인정하는 국제 표준 인증지침서인 SAE ARP를 분석하여 낙뢰 인증지침을 PAV에 접목하였다. PAV의 낙뢰에 대한 영향성을 전산 소프트웨어를 통해 분석하였고 향후 추진될 PAV 낙뢰 인증을 위한 실무지침 수립의 근거를 제시하고자 한다.
