ASC(Avionics System Computer) was developed to control weapon delivery and navigation sensors, and to perform man-machine interface with pilots for XKO-1 aircraft. The data communications between ASC and UFC(Up Front Controller), DC(Data Concentrator) were implemented by RS422 serial data bus. Also, SCIL(Standard Computer Interface Library) was designed to facilitate control and management of the computer hardware resources and is embedded in the ASC. These structures have a merit of noise immunity and a reduction of wire harness for signal lines, and enable OFP(Operational Flight Program) programmers to use the SCIL easily without knowing hardware details. Manufactured system was on installed on XKO-1, and peformed for BIT(Built In Test) and interface test with UFC and DC. The test results show that it meets the system requirements.

In this paper, we have described an aircraft captive flight test for the development test of weapon systems. We have conducted a captive flight test for the development of core onboard parts and sensors of airborne weapons and guided missiles. We have used KTX-1/XKO-1 aircraft as a platform for the captive flight test. In order to perform a captive flight test, we have made a captive test pod as a shape of external fuel tank in the XKO-1 and have modified XKO-1 aircraft for a system interface. We have taken a development test about all kinds of seekers, navigation & guidance systems, and core part of guided missile through the aircraft captive flight test.

지금까지의 기술자료관리는 수작업의 비효율성과 복잡한 절차로 인해 업무의 시간 손실을 발생시켜 왔다. 대용량 저장장치, 그래픽 디스플레이 및 네트워킹 같은 정보기술 진보는 효과적인 전자문서 처리를 가능하게 했다. 본 논문에서 기술하고자하는 XKO-1의 통합기술 정보시스템 모델은 방대한 문서 데이터베이스를 개발하고 XKO-1 항공기의 도면, 기술문서 및 비행시험 자료의 관리와 처리를 지원하기 위한 기술을 보여주기 위한 것이다. 또한 ITIS 프로그램은 워크플로우를 이용한 문서저장기능과 스캐너를 사용해서 문서를 디지탈화, 전자화, 색인화 및 압축화하여 데이터베이스에 저장할 뿐만 아니라, 프로세스에 따라 검색 및 분배된다.

In this paper, we summarize the results of free drop wind tunnel test, separation analysis and flight test in order to verify the safety during the separations of an external fuel tank and the LAU-131 rocket launcher from XKO-l. The wind tunnel test was conducted to show the safety in free drop of the stores and to gather the trajectory data for fine tune of MSAP(Multi-body Separation Analysis Program). The enhanced MSAP was then used to predict the trajectories of the stores with and without the ejector forces. A correlation of MSAP results for free drop case was also made to show the safety of jettison with the free drop type bomb rack. Moreover, the flight test was conducted. and its results were compared to analysis results. Finally, the safe jettison boundary was determined from the flight test.

A Decal Panel is developed for the Night Vision Imaging System of XKO-1 aircraft. The Decal Panel is a kind of lighting system kits and is installed on each system switch box in crewstation. The Decal Panel consists of upper panel made of polycarbonate and lower panel which is a printed circuit board. This paper includes the design, manufacture, test and evaluation of Decal Panel in addition to items and conditions of environmental test. Besides it is confirmed the Key for manufacturing a decal panel, is depth of paint, dry time period and frequency, and diffusion material for spreading of light.
