세계적인 여러 악재에도 불구하고 항공수요는 거의 매년 증가세를 유지해 오고 있다. 최근 세계 경기 회복세에 힘입어 Boeing 과 Airbus의 수주잔량도 10,639대로 역대 최고치를 보이고 있다. 또한 신흥발전국의 GDP 성장과 더불어 여행 빈도수의 증가에 따라 중국과 인도를 중심으로 아시아의 저가항공사(LCC)의 성장이 증가되고 있다. 이에 따라 대형 항공기뿐만 아니라 중형 항공기 시장도 점점 확대되고 있다. 향후 20년간 대형 항공기의 인도대수는 약 3만대 이상 될 전망이고, 중형 항공기는 12,800대가 인도될 전망이다. 하지만 항공시장의 감소주기 도래와 공급과잉, 유가상승과 같은 요인들로 항공 산업의 전망에 불확실성을 가져 올 수 있다. Despite of the several global disasters, the market demand has been maintaining the increase almost every year. Recently the global economic recovery causes the backlog of Boeing and Airbus to be at all time high as 10639 units. In addition of GDP(gross domestic product) growth in the emerging market, LCCs(low cost carrier) in the asia region continue to prosper according to the increment of trip per capita by leading from China and India. Therefore the regional aircrafts as well as jetliners also expand its market. For twenty years from now the delivery of jetliner will amount to over 30,000 units and the delivery of regionals reach at 12,800 units. However, the advent of decline cycle of aircraft market, the surplus of delivery surplus and the rise of oil price could be the uncertainties for aircraft market outlook.

무인이동체 산업은 4차 산업혁명과 밀접하게 연관된 신산업 중 하나이다. 하지만, 무인이동체 미래선도핵심기술개발사업단(이하 ‘무인이동체사업단’)에서 2016년부터 무인이동체 산업에 대한 실태조사를 시작하기 전까지는 한국의 무인이동체 산업의 통계 자료가 없었다. 무인이동체사업단에서는 구조화된 설문지를 사용하여 국내 무인이동체 산업체에 대해 조사를 수행해 왔다. 실태조사 연구 결과는 무인이동체 산업을 육성시키기 위한 정부정책의 기본 자료와 근거로 활용될 수 있다. The unmanned vehicle industry is one of the new industries closely combined with the fourth industrial revolution. However there has been no statistical data of the Korean unmanned vehicle industries before Unmanned Vehicle Advanced Research Center(UVARC) started a survey study on them from 2016. UVARC has performed its survey on the domestic unmanned vehicle companies using structured questionnaires. The results of survey study can be used as a basic data and rationale for establishing government policy to promote the unmanned vehicle industry.

For loads analysis of airplane, applicable regulation should be determined. Then, loads conditions are prepared from the regulation. Modeling for aerodynamic, mass, and structure are performed. Panel method is usually adopted for aircraft loads analysis to obtain air loads. The ARGON which is a multidisciplinary fixed wing aircraft design software co-developed by the KARI and TsAGI are used for loads analysis. The ARGON can be utilized for flutter and stress analysis as well as for flight and ground loads analysis. In this paper, flight loads analysis for wing structural design of the regional aircraft at the conceptual design phase are performed with the ARGON. FAR 25 is used for the regulation for the load analysis. Shear force, bending moment and torsion diagrams for the wing and shear force and hinge moment for the aileron are presented.

Recently strong interest is focused on unmanned vehicles as like drone (small UAV), autonomous vehicle, and HALE(high altitude long endurance aircraft). A few years ago, unmanned vehicle was considered only for military usage. But depending on technical development and increase of various market need, commercial market demand is increasing dramatically. In this paper, we investigated the market demand of unmanned vehicle which is operated on the ground and marine as well as sky. Furthermore, we performed the market forecast during next 15 years and tried to show our advancing direction of technical development.
