  • 자율운항선박시대에는 인공지능기술이 VR, AR과 결합하여 더욱 진화된 몰입형 경험을 제공할 수 있을 것이다. 몰입 기술은 사용자의 오감을 현혹시켜 실제와 유사한 경험과 감성을 제공할 수 있다. VR이나 AR을 통해 자율운항 시 선원이 운항에 몰입할 수 있고 가상의 선박과 상호작용할 수 있는 자연스런 환경을 제공해 주는 것이 필요하다. 본 연구에서는 자율운항선박시대를 대비하여 선원들이 VR이나 AR을 통해 자율운항 시에 몰입형 사용자경험을 구현할 수 있는 핵심 특성이

  • In this paper, pilot flight training procedure of VFR (Visual Flight Rule) flight procedure was investigated through basic aviation training device (BATD) using VR HMD (Virtual Reality Head Mount Display). In order to evaluate the efficiency of the pilot training, the experimental pilot group was divided according to the similar piloting ability, then same VFR flight procedure was carried out using both the VR BATD and the conventionl BATD. The comparison of the X, Y and Z position of the aircraft from the extracted flight data was conducted. As a result, it was confirmed that the VR BATD shows better steering training efficiency tendency than the conventional BATD.

  • In this paper, two different flight training devices were constructed to verify the effectiveness of a pilot training system based on a Virtual Reality Head Mount Display. VFR Flight Procedure and IFR Flight Procedure were conducted by high level pilots with Commercial Pilot Licence. Flight data and pilot's visual data for each flight procedure were extracted, compared and analyzed with two training systems. Finally, the effectiveness of the training systems based on the VR HMD was demonstrated by assessing the given mission and the flight results.

  • This study performed precision instrument landing procedures for pilots with a commercial pilot license using VR HMD flight simulators, and assuming that the center of the pilot's gaze is in the front, 3-D.O.F. head tracking data and 2-D eye tracking of VR HMD worn by pilots gaze tracking was performed through. After that, AOI (Area of Interesting) was set for the instrument panel and external field of view of the cockpit to analyze how the pilot's gaze was distributed before and after the decision altitude. At the same time, the landing results were analyzed using the Localizer and G/S data as the pilot's precision instrument landing flight data. As a result, the pilot was quantitatively evaluated by reflecting the gaze tracking and the resulting landing result using a VR HMD simulator.

  • In this paper, current application of VR in naval architecture and ocean eng. Design is surveyed and VR process is implemented in ship navigation system. So far, very sophisticated VR applications have announced but not published yet. The reason not published may be that the application is for the navy ship of which the information could not be opened to the public. Also there is another area implementing Simulation Based Design, i..e., visualization of the integration process from initial design to the manufacturing. Herein, the tendency of VR in this area is surveyed, so the international application of VR is introduced. Trough the analysis the most appropriate applicability of VR in this area can be distinguished. And to show the application, ship navigation VR is programmed using OpenGL graphics software.

  • The purpose of this study is to develop and technically implement the design and scenario of cabin safety contents for virtual reality (VR)-based cabin safety learning for aviation service majors. The process for developing VR cabin safety learning contents consisted of a total of four stages: learning stage, research stage, verification stage, and application stage. The cabin safety scenario items for the production of VR learning contents reflected the occurrence of an emergency, the procedure for survival from impact, and the evacuation procedure from the aircraft as the core. For the technical implementation of learning contents, modeling work is conducted by checking scenario reviews, types and numbers of objects related to equipment and facilities, and items of interaction. In addition, the connection work with the actual metaverse platform is carried out to enable the utilization of the manufactured facilities and equipment objects. Finally, application tests were carried out to reconfirm supplementary items.

  • As the domestic aviation industry develops, demand for pilots is increasing. As a result, the demand for flight training using flight simulation training devices that implement the same or similar interior of aircraft is also increasing. Despite this increase in demand, domestic laws, regulations and management systems related to flight simulation training devices have remained unchanged since 2009. As a result, the criteria for designation of new or developed flight simulation training devices are ambiguous. In addition, proper improvement of the current system should be prioritized for designation of new devices such as UAM and VR, along with developing flight simulation training devices. It is intended to present measures to improve the domestic flight simulation training system by investigating and analyzing advanced cases overseas.

  • 해상에서 운항되는 선박에서 인명사고가 발생하면 육상과 달리 적시에 의료지원을 받기 구조적으로 어렵다. 특히 연안선박의 경우 원양선에 비해 상대적으로 고령의 선원들이 승무하고 있기 때문에 인명사고가 빈번하며 인명사고에 취약하다. 본 연구는 AR과 VR과 같은 실감기술을 기반으로하는 연박선박의 원격의료지원 모델 개발하기 위한 방향성을 제시하고자 한다.

  • 2025년을 목표로 UAM을 상용화하겠다는 정부의 의지를 바탕으로 국가기관과 전 세계 기업을 중심으로 UAM 기체 개발을 포함한 여러 분야에서 놀라운 성과를 이뤄내고 있다. 또한 최근에는 도심항공모빌리티(UAM) 개념을 기반으로 도심 항공 운용과 관련이 없는 장거리 또는 근거리 도시 간 상용운용, 화물배달, 공공 서비스, 항공 관광, 개인/레저용 기체와 같은 사용을 포함하는 선진항공모빌리티(AAM; Advanced Air Mobility) 개념으로 진화하고 있다. 이처럼 UAM 산업이 기체 개발, Vertiport 설계 및 구축, 항행시스템 등의 다양한 분야에서 활성화되고 있지만, UAM을 이용한 승객 이동 시 저고도 운항 특성과 3차원 내에서의 속도감, 외부 환경에 의한 기체 흔들림 등으로 인한 승객의 공포심과 어지러움 등 신체적 문제에 관한 연구는 지금까지 거의 찾아볼 수 없는 상태이다. 따라서 본 연구에서는 헬리콥터를 활용하여 UAM의 예상 고도와 속도로 비행하면서 실제 영상을 촬영, VR과 Motion이 장착된 UAM 시뮬레이터를 활용하여 일반인들에게 체험함으로써, 추후 UAM 실제 운항 시 발생할 수 있는 승객들의 공포심과 어지러움 등의 신체적 반응을 확인하고, 문제점을 분석하고자 한다.

  • According to the aviation statistics, tail strike incidents and accidents are cyclic. Although many tail strikes occurred during takeoff, these are less than during landing cases. Many cases are related on human factors. In my opinion it is possible to analyze the causes of takeoff tail strikes to some extent. There are major casual factors of tail strike during takeoff such as; (1) Mis-trimmed horizontal stabilizer (2) premature rotation prior to $V_R$ (3) Excessive pitch up rate during rotation (4) Improper use of the flight director. Among these causes improper use of flight director is excluded in this paper because it is recommended that pilot should use flight director after airborne. So I analyzed the other three causes as following. Firstly, because mis-trimmed stabilizer is related to center of gravity(CG), the relationship between stabilizer and CG is reviewed. Secondly, concerned premature rotation prior to $V_R$ I reviewed the background of rotation speed($V_R$) establishment and analyzed theoretically what speed leads to tail strikes. Thirdly, concerning excessive pitch up rate during rotation I analyzed what excessive pitch up rate can decrease ground clearance while using FDR data.
