고정익 항공기 구성품 고·저온 시험 대체 유효성 검증 방안 연구 = A Study on the Validation Method of High/Low Temperature Test Replacement of Fixed-wing Aircraft Components

다국어 초록 (Multilingual Abstract)

This study explores the possibility of an alternative test method to efficiently verify the temperature impact of radios mounted on fixed-wing aircraft. Radios mounted on aircraft are exposed to extremely high and low temperature environments during flight. The test to verify high- and low-temperature requirements is carried out with an experimental method using an environmental chamber based on the MIL-STD-810 standard, but this method takes a considerable amount of time and money. In this study, the possibility of replacing the existing test procedure is analyzed by comparing its results with test results of high- and low-temperature components of radios with improved performance by utilizing the measured data accumulated in a pre-airplane temperature test. In addition, the effect of changes in the aircraft structure after the whole environmental test on the temperature distribution was technically reviewed, and the effect of structural differences on the performance of the radios was also considered. The results of this study suggest the validity of the proposed verification approach using existing environmental test data, and can be used as basis data to achieve efficiency from future environmental tests on radios for aircraft, and for verification period/cost reduction.
