As unmanned aerial vehicle (UAV) has been utilized for military operation, efficient ways for controlling UAV has been necessary. In particular, instead of conventional approach using console control, speech recognition based UAV control is essential for military environments in which rapid command operation is required. But research on this novel approach is not actively studied yet. In this study, we introduce efficient ways of speech recognition system operation for voice-driven UAV control, focusing on mission command control from manned aircraft rather than ground control center. We propose an efficient way of system operation for UAV control in cooperation of aircraft and UAV, and verify its efficiency via speech recognition experiment.

This study focuses on building the wartime air operation model to evaluate the airfield capability. There are some uncertainties in the process of air operation such as mission flying time, turn around time, mission damage or kill rate, weather condition, and so on. Airplanes, on the way to the airbase after completing mission flight, may have been in queue on the holding point due to the unusable condition of airfield. And then, they may sometimes need to go other airbases due to the shortage of fuel. Under those uncertainties, this model is to evaluate the airfield capability in the wartime air operation using simulation.

최신 전투기로 발전할수록 증가되는 소프트웨어 의존도와 네트워크 중심전으로의 작전 수행 개념의 변화, 그리고 무기체계에 대하여 지속적으로 발전하는 사이버 위협의 증가는 전투기 소프트웨어에 대한 강화된 보안 대책을 요구하고 있다. 이러한 상황의 변화는 전투기의 운용 및 소프트웨어 결함에 대한 감항인증 뿐만 아니라, 전투기 소프트웨어에 대한 사이버 위협의 보안 대책도 함께 요구한다. 따라서 본 연구에서는 항공기 및 시스템 감항 보안 인증기준인 DO-326A와 DO-356을 적용하여 전투기 운용 환경을 고려한 항공무기체계의 특성과 항공기에 대한 사이버 공격에 대해 살펴보고, 이를 바탕으로 감항 보안 프로세스를 적용해 본다.

효과적인 조종사의 임무수행을 지원하는 소프트웨어인 비행임무지원체계가 현대 항공작전의 필수 요소로 주목 받고 있다. 첨단 항공기를 위한 비행임무지원체계의 개발을 위해서는 많은 시간과 비용이 소요되며 높은 개발수준을 요구하고 있으나, 국내 실정은 기본 프레임워크 조차 없는 단일 응용 프로그램 개발 수준에 불과하다. 따라서 차기 항공기를 지원하는 향상된 한국형 비행임무지원 체계를 개발함에 있어, 재사용이 가능하며 품질을 향상시켜줄 수 있는 프레임워크의 개발은 매우 중요한 과제이다. 이에 본 논문에서는 한국형 비행임무지원체계의 개발에 적합한 개발 프로세스를 제시하고, 이에 따른 비행임무지원체계의 프레임워크의 설계 및 개발 방향을 제시하고자 한다.

조류충돌(Bird Strike)은 경제적 손실, 인명적 피해를 야기하여 공군의 항공작전을 제한하는 위협요소이다. 현 공군에서는 조수퇴치조(Bird Alert Team)의 경보 발령에 의존하거나 조류의 행동을 연구하는 등 인적 역량에 의존하는 시스템을 채택하고 있다. 본 연구는 CNN을 이용하여 활주로의 유해조류를 인식 및 분류하는 자동화 시스템에 대한 제안이다. 웹캠을 활용한 실시간 유해조류를 인식하는 연구를 통해 향후 운항관제대와의 연계, 지향성 조류퇴치 장비와의 연동 방안을 제시하여 공군의 조수퇴치조(Bird Alert Team)에 대한 자동화를 실현하고 공군에서 추진중인 스마트 비행단에 이바지하고자 한다.

Armed helicopter is an integral part of armed forces, which conducts vital missions, such as anti-armor attack, close air support, escorting air assault operations, and reconnaissance. A typical cockpit arrangement of armed helicopters has been a tandem configuration. This is to reduce the frontal area, which in turn increases the forward speed as well as reduces the chance of being hit by enemy fires. However, many armed helicopters in the world are now being developed as a side-by-side configuration. Such configuration is quite different from the conventional cockpit arrangement in light of the crew communications and situational awareness. Therefore, the main objective of this study is to find the optimized combination of mission tasks among pilots in a side-by-side configuration cockpit by measuring the workload using the NASA Task Load Index method. The experimental results indicate that the workload of crew members differ as disparate tasks are being performed.

This paper presents a methodology for evaluating suitability of a manned-unmanned aerial vehicle team for a complicated mission. The study identified vehicle performance, equipment performance and level of autonomy as the key factors that affect the mission effectiveness. A manned and an unmanned aircraft were compared, and their performance was quantized in these respects. SEAD was chosen as a representative manned-unmanned team mission. The SEAD mission was broken down to a sequence of tasks. Mission experts evaluated the importance of each mark item for the mission legs. Combining the results showed proper type of aircraft for each leg depending on the complexity, safety, and importance of the task. Finally, the whole mission plan was laid out as a time-based sequence which alleviate pilot workload significantly.

Modern state-of-the-art military aviation assets are operated with independent embedded real-time operating systems(RTOS). These embedded systems are made with a high level of information assurance. However, once the systems are introduced and installed on individual platforms for sustaining operational employment, the systems are not actively managed and as a result the platforms become exposed to serious threats. In this paper, we analyzed vulnerability factors in the processing of mission planning data and maintenance-related data for fighter aircraft. We defined the method and form of cyber attacks that modulate air data using these vulnerabilities. We then proposed a detection module for integrity detection. The designed module can preemptively respond to potential cyber threats targeting high - value aviation assets by checking and preemptively responding to malware infection during flight data processing of fighter aircraft.

This study presents a method to efficiently advance the Republic of Korea's Unmanned Systems through the analysis of the development of the U.S. Unmanned System Policy. After the occurrence of the September 11 attacks, the U.S. developed Unmanned Systems as a part of RMA and became the leader in this area. The system went through numerous trials and errors during the development and acquisition. From these experiences, the U.S. had embodied Unmanned Systems acquisition methods by establishing Unmanned Systems Development Guidance and DoD Autonomy Community of Interest in 2012. In addition, as diverse unmanned programs started to proceed, it promoted Core Technology development sharing and simplification of functions of the Unmanned Systems to exclude budget-wasting elements such as duplication of programs. The Republic of Korea must politically build a collaborative system between industry/academia/research institute/military and apply evolutionary development strategies from the first step of the development of the Unmanned Systems the future Game Changer. In operations, concepts of the Manned/Unmanned Systems complex operation should be established and intelligent S/W, Open System, and Cyber Security technologies to materialize them developed.

Link-16 is a representative TDL operated by US air force and NATO and supports structure of Multi-net. Under Multi-net, military operation can be conducted effectively since terminal nodes in Link-16 hop over total frequency band simultaneously. As air traffic is rapidly increasing, new aeronautical system is introduced or existing system should be expanded to accommodate increasing air traffic and frequency band assigned for operating this system is scarce. It is scheduled to implement frequency remapping to solve frequency scarcity. With limited frequency band for operating Link-16, as frequency remapping is implemented, degradation of Multi-net performance can happen since multiple access interference in Link-16 is increasing so it is difficult to conduct multiple military operations. Thus, Group-based frequency hopping scheme is proposed to solve this problem. We verified the performance of the proposed scheme is improved.
