It is indispensable for a missile to track a target under the flight condition since the tracking capability affects the system performance considerably. The best way to verify the tracker's performance is flight test while it costs too much. Consequently, captive flight test or CFT has an important role in the development of a missile system. CFT, however, cannot simulate missile dynamics and is an offline and open-loop test. In this paper, we propose a new integrated-flight simulation(IFS) method using CFT imagery to overcome the limitation of synthetic image-based IFS method. This method increases the utilization of CFT's outputs and compensates the reality of imagery which lacks in the synthetic image-based IFS. Using this method make it possible to verify the system capability in various simulation modes.

The flight test is last means of compliance to satisfy airworthiness standards and important to evaluate the performance and safety of the developed aircraft. The flight test technologies are obtained from great numbers of experiences and know-hows and protected. In addition, flight test should be conducted efficiently since its various test conditions and items. Therefore, it is requisite to secure efficient flight test methods. This paper discusses the flight test methods for take-off and landing performance and two kinds of techniques are proposed. By performing real flight tests, they are compared with each other and analyzed through the flight analysis.

The exact performance simulation of propulsion system is a key element in the prediction of the aircraft performance. The specification performance analysis using the installed loss of KT-1 showed a large difference with the engine performance measured during the flight tests. This indicates that a method to estimate the more exact performance is needed. The study on the performance simulation with performance map correction along the engine operating line shows the good consistent results through all the flight conditions and engine conditions. The correction factors of the map were resulted from the comparative analysis between the flight test and the simulation of installed engine performance.

In this study, the engine performance data was extracted and analyzed through the flight test of Smart UAV which is tilt rotor aircraft. The flight test was conducted for the transition flight regime where the tilt angle of prop-rotor varies from 90 degree to 0 degree and vice versa. The engine performance data such as engine power and specific fuel consumption gathered from flight tests were compared well with the results of engine performance analysis program.

고흥 항공센터에 2019년(예정) 신규 활주로가 설치되고, 비행시험 관련 시설, 장비들을 단계적으로 구축하여 국가 비행종합성능시험장으로 운영할 예정이다. 국가 비행종합시험장은 공항이 아닌 비행장으로 운영할 예정이다. 비행장에는 특별히 정하는 운영규정이 없는 실정이다. 그러나 특수한 목적으로 신설되는 국가 비행종합성능시험장을 보다 안전하고 효율적으로 운영할 수 있도록 관련법규와 국내 공항 및 비행장 운영관리 현황 조사, 해외의 비행장 운영관련 법규와 운영실태 조사, 해외 항공 전문가 자문 및 출장을 통하여 향후 국내 관련법규 제정 및 비행종합시험장 운영 시 활용할 수 있도록 지침을 제시하였다.

This is a comparative study of three inertia navigation units and focuses on the verification of reliability about GPS/INS for the SmartUAV(DGNS). Those GPS/INS have been tested using a manned aircraft and an automobile. The comparative aspect of units include details about the GPS positions and the inertia sensor performance. With the flight scenario, the DGNS guarantees the reliability of the navigation operation and performs the flight test for the development of the SmartUAV.

In order to ensure the individual and mutual performances among the telemetry system, tracking system, flight termination system, GPS, and inertial navigation & guidance system which are installed in the KSLV-I 2nd stage and ground equipment of the Naro space center, flight test using a light airplane is required. Since the high degree of test efficiency is fulfilled through the minute plan and analysis about selection of the equipment which are applicable to the test, harness, operation strategy, and antenna installation. KSLV-I communication environment and flight profile should be precisely taken into account during the flight test. In this document, overall aspect of the KSLV-I 2nd stage equipment specification, a rack for the installation, harness, the airplane specification, and flight route which are required for the effective flight test are presented.

우주추진기관의 모든 부품은 생산 시 규정된 절차를 거쳐서 작동의 이상유무를 확인하는 시험을 거친다. 우주추진기관은 특별한 경우를 제외하고는 실 비행 상태에서 시험하기가 어렵거나 불편하기 때문에 지상에서 시험을 수행하여 성능 및 안정성 등을 확인하게 된다. 지상연소시험을 수행하기 위해서는 비행용 엔진을 대상으로 엔진 메니폴드에 비행 시와 같은 조건의 추진제가 공급될 수 있게 해줘야 한다. 기존에 시험장이 이미 구축되어 있는 경우 엔진의 운용조건에 맞추어 엔진에 맞게 엔진과 시험설비 연결부분이 수정되게 된다.(중략)
