Abstract

Conventional radar absorbing materials are difficult to apply in high temperature due to their low heat resistance. To enhance the survivability of aircraft, it is essential to apply radar absorbing performance at high temperatures. In this study, we developed a high temperature electromagnetic performance evaluation facility using arc plasma. The developed facility can heat specimens up to 1100℃ at a rate of 500℃/min. Using the developed facility, changes in the performance of the radar absorbing materials with temperature variations were measured.

일반적인 전파 흡수 재료는 낮은 내열성으로 인해 비행체 배기구 영역 및 주변부 등의 고온 환경에 적용하기 어렵다. 생존성 향상을 위해서는 고온 영역에 전파 흡수 성능 적용이 필수적이다. 이 연구에서는 아크 플라즈마를 이용하여 실제 급속 고온 환경을 모사한 전자기 성능 평가 장치를 개발하였다. 개발된 장치는 약 1100℃ 까지 가열 가능하며, 분당 승온 속도는 약 500℃/min 이다. 개발된 장치를 이용하여 전파 흡수 재료의 전자기 성능 평가 결과, 온도에 따른 전파 흡수 성능의 변화를 측정할 수 있었다. 또한 4회 반복 가열 평가를 통해 히스테리시스 평가가 가능한 장치임을 확인하였다.
