With increasing interest in aviation leisure sports, the demand for ultralight aircraft has increased, highlighting the necessity for robust structural design of the aircraft. In response, this study conducted static structural analysis and free-fall analysis of fuselage frame of ultralight aircraft. Robust design and crashworthiness under operational load conditions and vertical impact scenarios were evaluated by assessing maximum stress and safety factors. Analyses were performed using finite element method-based software ANSYS Workbench. Results including stress distribution and strain were analyzed to verify the safety of the designed fuselage frame. Additionally, this study predicted excessive deformation and failure locations of the fuselage frame during vertical drop impacts.

항공기의 속도는 총알과 비교하여 그 범위가 매우 넓다고 할 수 있겠다. 굳이 제로의 속도도 가능한 기구를 차지하더라도 동력장치를 가진 현대의 초경량항공기도 불과 30여km의 속도로 비행이 가능하며 소리의 속도를 능가하는 전투기의 비행속도까지 항공기가 가지는 운동속도는 그 폭이 매우 넓다는 것을 알 수 있다.<중략>

By aircraft from Aviation regulations and institutional regulatory framework for ensuring the safety is secured. State-of-the-art aircraft, according to the type of development and diversification, modernization and new types of aircraft are operated. In particular, light aircraft and ultralight flying device such as the gyro-plane and unmanned flying devices is introduced a new device, and the device operates at these flight in accordance with the standards of the Aviation Act regulations may not occur often. Variety of light aircraft and ultra-light aircraft assembly, can be adapted for a person engaged in the business of aviation safety management and to perform the legal basis was established. Depending on the classification of newly introduced aircraft, the biggest change is the introduction of the concept of the LSA. In Korea, the various light aircraft are operating, but these aircraft range not clearly Aviation Regulations had difficulty in ensuring safety. This study examined the differences between international rules and regulations of Korea about the classification of aircraft. The LSA are included in aircraft categories internationally, but LSA will not be included in the aircraft categories, which is one of a range of powered flight device exists in Korea Aviation Act. Limit for maximum continuous power speed in a LSA, it is a limit on the right of the people who want using the high-performance plane. Also it is an international trend does not fit in, and is consistent with the intent of LSA manufacturer. Delete the content from a range of future aviation law revisions and light aircraft-related provisions to limit the maximum continuous power speed is considered to be suitable for the purpose of introducing the light aircraft industry. The laws and regulations set up in order to ensure the safety of ultralight aircraft categories existing in ultralight aircraft that exceeds the purpose of the introduction of LSA technology development at home and abroad, and is intended to reflect. These standards complement of aircraft operation is not appropriate for the situation unless the country is difficult to ensure the safety of operations. Also developed in other countries, the introduction of aircraft operating in the country, so many problems occur early revision is required.

정부에서 제시하고 있는 항공레저산업의 활성화를 위해서는 전국에 경비행장을 많이 건설하여 운영할 수 있는 인프라를 제공해야 하지만, 현실적으로 개발이 된 곳은 많지 않다. 그래서 경항공기, 경량항공기 및 초경량비행장치 관련 지속적인 수요 증가에 대비하고, 경항공기, 경량항공기 및 초경량비행장치 산업 활성화를 위한 "경(소형)비행장 개발의 표준화"를 통한 개발 방안에 대하여 생각해보고, 그 사례로 경남 사천 지역의 사천 송포 미래창조 첨단산업단지 조성 사업을 하면서 경비행장을 건설을 계획하고 있어 "경비행장 개발의 표준화"에 객관적인 연구에 의거 그 입지선정 타당성을 검토해보고자 한다.

필자는 고등학교 때 시작한 사진이 인연이 되어 대학과 공군 항공사진병, 10년간 다닌 첫 직장까지 20년 넘게 사진을 업으로 인연을 맺었습니다. 비행기를 좋아하다보니 공군 항공사진병을 지원했고, 회사생활에서도 많은 항공 촬영과 비행기 사진을 접할 기회가 많았습니다. 요즘도 비행기가 좋아서 초경량항공기 조종을 배우고 있다고 자랑한 덕분에 항공기 촬영에 대한 원고청탁을 받고 이제야 내가 좋아하는 두 가지를 동시에 할 수 있어 기쁜 마음으로 수락했습니다. 이를 두고 ''''일석이조''''라고 하든가요.

The base of leisure air activities are consistently expanding and its demand is expected to increase attributed to GDP growth and people's interest in its activity. Utilizing Visual Flight Rule, light sport aircrafts and ultra-light aircrafts are not under the effect of air traffic control center, which resulted in passenger injury due to emergency landing for adverse weather conditions and technical issues after pulling into mountain area, ocean and even urban area. Such events encouraged safety consciousness toward leisure aircraft activities and developing a measure to prevent a recurrence of the accident. This research focuses on suggesting compositive system for preventive safety management system by providing user based Flight information service and operating effective system, necessary for leisure aircraft activities.
