선진 항공기 개발국들은 인간공학적인 조종사-항공기 인터페이스의 중요성을 제2차 대전시에 깊이 인식하였으며, 현재는 개발되고 있는 항공기별로 40~50명의 연구원들이 인간공학적 연구를 하고 있다. 또한 항공기 무기체계 개발과 마찬가지로 전차, 군함, 잠수함, 유도 미사일 등의 무기체계에도 반드시 사용자의 인간 공학적인 요소들이 적용될때, 성능이 최대로 보장될 것이다

In wartime conditions, the communication system of military aircraft is exposed to jamming, and it is necessary to mount communication equipment with high anti-jamming performance in order to perform air operations smoothly even in an environment where jamming attempts are made. In this paper, we check in detail the jamming and anti-jamming technology that can be applied to wireless communication, and the data disclosed on the difference in specifications of the next-generation anti-jamming radio with frequency hopping method and the improvement of anti-jamming performance according to these changes. It was briefly analyzed within the scope. In addition, the points to be considered when designing a new domestic aircraft and the possibility of installing the next-generation anti-jamming communication equipment on the currently operating aircraft were confirmed, and the tactical usefulness of improving the anti-jamming capability of the next-generation anti-jamming communication equipment was confirmed.

The demands of Unmanned Aerial Vehicles (UAVs) are growing very rapidly with the era of the 4th industrial revolution. As the technology of the UAV improved with the development of artificial intelligence and semiconductor technology, it began to be used in various civilian fields such as hobbies, bridge inspections, etc from being used for special purposes such as military use. MAVLink (Macro Air Vehicle Link), which started as an open source project, is the most widely used communication protocol between UAV and ground control station. However, MAVLink does not include any security features such as encryption/decryption mechanism, so it is vulnerable to various security threats. Therefore, in this study, the block cipher is implemented in UAV to ensure confidentiality, and the results of the encryption and decryption performance evaluation in the UAV according to various implementation methods are analyzed. In addition, we proposed the security requirements in accordance with Common Criteria, which is an international recognized ISO standard.

Among various fields of the CNS/ATM, the surveillance field which includes ADS-B system, MLAT system, and WAM system is implemented. These next generation systems provide superior performance in tracking aircrafts. However, They still have error. In this paper, filtering algorithm is proposed in order to enhance aircraft tracking performance of ADS-B, MLAT, and WAM systems. The proposed method is a Robust Interacting Multiple Model filter, called Robust IMM filter, that improves IMM filter. The Robust IMM filter can not only improves the aircraft tracking performance but also track aircraft continually using estimates calculated from the filter when data losses occur. The simulation results of the proposed aircraft tracking methods show that the filtering data provides a better performance up to an average of 19.21%.

The performance analysis code has been developed for vertical take-off and landing(VTOL) UAV which can be utilized as a trade analysis tool in the pre-conceptual design phase. The UAV requires VTOL capability and high speed cruise performance. The main logic of this performance analysis code is to estimate performance parameters of each mission segment by mission fuel weight iteration. The reliability of this performance analysis code is discussed by comparing the data of existing dual flight mode VTOL UAVs such as Boeing CRW and Bell Tilt Rotor.

지난 8월 1일 "군용항공기 비행안전성 인증에 관한 법률"이 본격 시행됐다. 국제적 수준의 비행안전 인증 체계를 마련함으로써 이제 우리도 우리 손으로 만든 국산 군용항공기의 비행안전성을 체계적으로 검증하고 국가가 그 성능을 보증할 수 있게 된 것이다. 뿐만 아니라 감항인증 관련 비용 및 시간을 대폭 단축할 수 있어 우리 손으로 만든 KT-1과 T-50의 해외 수출에도 큰 도움이 될 것으로 전망되고 있다. 군용항공기 감항인증제도 시행과 관련하여 현재까지의 진행경과 및 감항인증제도 도입 의의를 정리했다.

There are typically two categories of Flight Test Programs- commercial and military. Commercial flight testing is conducted to certify that aircraft meets all applicable safety and performance requirements of government certifying agency. Military programs differs from commercial in that the government contract with the aircraft manufacturer to design and build an aircraft to meet specific mission capabilities. The final phase of military aircraft flight test is the Operational Test(OT). OT is conducted by a government-only test team with the dictate to certify that the aircraft is suitable and effective to carry out the intended mission. This paper presents the current trends of military aircraft airworthiness certification using civil aircraft certification practices.
