도심항공모빌리티 비행체 PAV 탑승자 실내행위에 영향을 미치는 제약 요소 도출 및 인체 영향 수준에 따른 설계 기준 = Derivation of Constraint Factors Affecting Passenger’s In-Vehicle Activity of Urban Air Mobility’s Personal Air Vehicle and Design Criteria According to the Level of Human Impact

다국어 초록 (Multilingual Abstract)

Recently, prior to the commercialization of urban air mobility (UAM), the importance of R&D for air transportation-related industries in urban areas has significantly increased. To create a UAM environment, research is being conducted on personal air vehicles (PAVs). They are key means of air transportation, but research on the physical factors influencing their passengers is relatively insufficient. In particular, because the PAV is expected to be used as a living space for the passengers, research on the effects of the physical elements generated in the PAV on the human body is essential to design an interior space that supports the in-vehicle activities of the passengers. Therefore, the purpose of this study is to derive the constraint factors that affect the human body due to the air navigation characteristics of the PAV and to understand the impact of these constraint factors on the bodies of the passengers performing in-vehicle activities. The results of this study indicate that when the PAV was operated at less than 4,000 ft, which is the operating standard, the constraint factors were noise, vibration, and motion sickness caused by low-frequency motion. These constraint factors affect in-vehicle activity; thus, the in-vehicle activities that can be performed in a PAV were derived using autonomous cars, airplanes, and PAV concept cases. Furthermore, considering the impact of the constraint factors and their levels on the human body, recommended constraint factor criteria to support in-vehicle activities were established. To reduce the level of impact of the constraint factors on the human body and to support in-vehicle activity, the seat's shape and built-in functions of the seat (vibration reduction function, temperature control, LED lighting, etc.) and external noise reduction using a directional speaker for each individual seat were recommended. Moreover, it was suggested that interior materials for noise and vibration reduction should be used in the design of the interior space. The contributions of this study are the determination of the constraint factors affecting the in-vehicle PAV activity and the confirmation of the level of impact of the factors on the human body; in the future, these findings can be used as basic data for suitable PAV interior design.

최근 도심항공모빌리티(UAM) 상용화에 앞서 도심 내 항공 교통수단 관련 산업에 대한 연구개발 중요성이 급격히 증가하고 있다. 도심항공모빌리티(UAM) 환경을 조성하기 위해서 핵심 항공 이동 수단 비행체인 개인용 항공기 (PAV) 기체에 관한 연구가 수행되고 있으나, 탑승자 관점의 연구가 상대적으로 부족한 상황이다. 특히 PAV는 탑승 자의 새로운 생활공간으로 활용될 것으로 예상되기 때문에 탑승자의 실내행위를 지원하는 실내공간 설계를 위해서 는 PAV 기체에서 발생하는 물리적 요소가 인체에 미치는 영향에 관한 연구가 필수적으로 이루어져야 한다. 이에 본 연구의 목적은 PAV의 공중 운항 특성으로 인해 인체에 영향을 주는 제약 요소를 도출하고, 이러한 제약 요소가 실내행위를 수행하는 탑승자 인체에 미치는 영향을 파악하는 것이다. 본 연구 결과, 항공 이동 수단 비행 기체 PAV 는 4,000ft 이하에서 운항해야 하는 기준에 따라, 운항고도에 따른 제약 요소는 소음, 진동, 저주파 운동에 의한 멀미 로 나타났다. 이러한 제약 요소가 실내행위에 영향을 미친다는 관점에서 PAV에서 행할 수 있는 실내행위를 자율주 행 자동차, 비행기, PAV 컨셉 사례를 활용하여 도출하고 인체에 미치는 영향과 수준을 고려하여 실내행위 지원을 위한 제약 요소 권장기준을 설정하였다. 또한 실내행위 지원을 위한 제약 요소의 인체 영향 수준을 감소시키기 위해 서는 시트의 형태 및 내장기능(진동 저감 기능, 온도조절, LED조명 등), 개인 좌석별 지향성 스피커를 활용한 외부소 음 감소, 소음과 진동 감소를 위한 내장재 등을 실내공간 설계에 반영해야 함을 제시하였다. 본 연구는 PAV 실내행 위에 영향을 주는 제약 요소를 도출하였고, 인체에 미치는 영향 수준을 확인하였으며, 추후 PAV 실내 설계 시 기초 자료로써 활용할 수 있다는 점에서 의미가 있다.
