This paper describes development contents and flight tests of an ACMI simulator based on LVC integrating architecture. ACMI is the system that provides air combat training and ground bombing training for improving fighting efficiency, that is the live simulation involving real people to operate real systems. ACMI simulator was developed for technic acquisition of LVC interoperability by using data link communication. ACMI simulator simulated maneuvering of a fighter by operating an UAV, a fighter can be distinguished from an UAV by maneuvering characteristics. This study proposes maneuvering simulation method by using flight data of the UAV, and performed its flight test for verifying similarity of fighter maneuvering.

This paper describes the parachute dynamics modeling and simulation results for the development of training simulator of a HALO (High Altitude Low Opening) parachute, which is currently in use for military purposes. The target parachute is a rectangular shaped parafoil and its dynamic model is derived based on the real geometry data as the 9-DOF nonlinear equations of dynamics. The simulation was conducted through the moment of inertia and its aerodynamic derivatives to reflect the real characteristics based on the MATLAB/Simulink. In particular, its modeling includes the typical characteristics of the added mass and moment of inertia, which is shown in the strong effects in Lighter-Than-Air(LTA) flight vehicle. The proposed dynamic modeling was evaluated through the simulation under the spiral turning flight conditions of the asymmetric control inputs and compared with the performance index in the target parachute manual.

In 2017, the world's first WIG ship (WIG: Wing In-Ground) pilot's license written test was conducted in Korea. The WIG ship is a ship that combines the characteristics of ships and airplanes. Therefore, the pilot of the WIG ship was allowed to apply only for those who had the aircraft pilot's license and the 6th class marine nautical license. The WIG ship pilot's license system was first introduced by Korea, so there are no international standards for the license system, and the introduction of a domestic qualification system also requires institutional arrangements due to various restrictions such as pilot training. However, in order to become a valuable industry as a future growth engine for the ocean, several urgent problems need to be solved, and that is the training of manpower for WIG ships. Therefore, I reviewed the institutional issues related to pilot training as this subject. Since 2001, various countries around the world have been discussing this issue, centering on IMO, and Korea has continued to participate and cooperate in IMO meetings. And the national qualification test for surface flying ships was conducted in Korea from 2011. However, there are still problems to be solved, and I pointed out the advancement of the manpower training system, the education and training system, and the designated national educational institution system. As a solution to this, it was suggested through the improvement of the license system and the operation of designated educational institutions. Among these solutions, I believe that the best way is to entrust the operation of designated national educational institutions to private educational institutions. However, I propose a plan that the government entrusts to private educational institutions, but the government is responsible for licensing and supervision. WIG ship will be a new market for the aviation industry and aviation workers.

모션플랫폼은 4D 효과의 가장 큰 부분을 차지하는 모션을 제시하는 장비로써, 영화, 엔터테인먼트, 군용 비행 조종훈련, 특수장비 전문가 양성 등의 다양한 응용분야에서 가상현실 기술과 접목되어 적절한 모션을 제공함으로써 사실적인 체험을 극대화할 수 있도록 한다. 기존의 초대형 정밀 군사 시뮬레이터를 유지하기 위한 공간과 비용을 줄이고자 하는 시도와 함께, 단순히 순간순간의 충격만을 전달해주는 저가의 4D 의자가 주는 효과의 한계성을 뛰어넘고자 하는 요구사항이 증가함에 따라, 그 접점에서 새로운 형태의 모션 제공을 통해 모션플랫폼의 신 시장을 창출될 것으로 기대된다. 본고에서는 가상현실을 기반으로 한 모션플랫폼을 응용분야와 동작방식에 따라 분류해 보고, 그에 따른 시장 및 기술개발의 지향점에 대해서 기술한다.

최근 드론이 상용화되면서 전문가뿐만 아니라 일반 사람들이 실생활에서 드론을 사용하는 사례가 늘어나고 있다. 하지만 드론을 원하는 대로 안정적으로 조종하기 위해서는 오랫동안 훈련을 해야 한다. 현재 드론을 정확하고 안정적으로 비행할 수 있도록 지원하기 위한 여러 가지 연구들이 활발히 진행되고 있다. 본 논문에서는 드론이 전복되거나 원치 않는 방향으로 이동하는 것을 방지하기 위해 드론의 기울임 정도를 예측하는 방법을 제안한다. 이를 위해서 드론의 센서 값과 프로펠러의 회전속도 값을 인공 신경망을 이용하여 학습시키고, 그 결과 드론이 기울어지는 방향을 예측한다.

FAA AC120-40B Level D flight dynamics model for T-50 Full Mission Trainer was successfully developed. Since AC120-40B Level D requires the quantitative validation tests for simulation model compared with flight test data, T-50 flight test data for each validation test item was gathered, and also automatic test environments which include AFT (Automatic Fidelity Tester) and STA (Simulation Test Analyzer) were developed. The final test results after the iterative test-tuning processes were all within the tolerances specified in AC120-40B Level D. Qualification Test Guide, QTG contains the detail test processes and results.

초등훈련기 KT-1의 주 추진기관인 터보프롭엔진(PT6A-62)의 정상상태성능해석 프로그램을 개발 하였다. 비행 마하수 0의 조건에서 장착손실을 고려하여 정상상태 성능해석을 수행하였다. 해석결과는 엔진 제작사에서 제시한 성능 및 상용 정상상태 성능해석 프로그램인 GASTURB와 비교하였다. 해석결과 공기유량, 축마력은 고도상승시 감소함을 나타내었고 비 연료 소모율은 미소한 상승을 확인할 수 있었다. 장착조건과 비 장착 조건의 비교 결과 엔진 전체 손실이 증가할수록 축 마력은 감소하고 비 연료 소모율은 증가함을 확인할 수 있었다.

An aircraft simulator for ergonomics testing and pilot training was developed from the joint work Agency for Defense Development(ADD) and Daewoo Heavy Industry, LTD, in Korea at first time. It is basically to satisfy the requirements established by FAA-AC-120-40C ( 1995-JAN-26). The aircraft simulator will be used mainly for ergonomics testing and pilot training for basic trainer on ADD and Korea Air Force in near futrue. This simulator reproduces faithfully the cockpit and flight characteristics of the KTX-1 aircraft. It is one of the latest full flight simulators that have the CGI(computer graphic image) visual system and six degree of freedom motions system. Development efforts focused on user-oriented design approach for ergonomics testing and flight training of pilots. Main characteristics of each subsystem are described such as cockpit, instruments, control loading system, motion system, visual system, aural system, instructor operation station and aircraft simulation softwear.

In order to study the correlation between the pilot's cognitive ability and recovery ability by applying a physical element that can cause spatial loss of position to the pilot, a turntable was installed on the top of the motion system to give a quantitative rotational error. We propose a method of simulating flight movement to reduce a difference in feeling and an intuitive method of forward kinematic analysis.
