초록

전북대학교 고온플라즈마응용연구센터에서는 지구 재진입 및 고온재료의 열부하 평가를 위해 0.4 MW 급 아크가열플라즈마 풍동을 이용한 내열재료의 삭마 거동 등을 연구해 오고 있다. 아크가열 플라즈마 풍동은 고엔탈피 플라즈마를 발생시켜 다양한 고열부하의 극한 환경을 만들어 낸다. 이를 위해서는 플라즈마 토치내에 공기유량과 입력전류 등을 조절하여 다양한 열유속을 형성한다. 본 연구는 0.4 MW 아크가열 플라즈마 풍동의 다양한 방전 특성에 대해 조사하였다.

Thermal protection materials (TPMs) are very crucial for the survival of any re-entry space vehicles. One of the systems used for rigorous validation of TPMs is an enhanced Huel type segmented arc-heated plasma wind tunnel. A 0.4 MW class arc-heated plasma wind tunnel has been constructed at Chonbuk National University which is capable of producing high enthalpy supersonic flow. In this paper we have studied the characteristics of plasma flow according to power and mass flow parameters.
