Abstract

Fire is one of important checkpoints in crewed exploration systems, where men inhabit in space. In space, astronaut can't escape from fire out of a spacecraft and not expect any help of fire fighters, either. Accordingly, the best way to stand against fire is to prevent it. But, when fire occurs in space, flame behaviors are quite different from those observed on earth because of micro- or zero-gravity in space. The present paper introduces major research results on flame behaviors under microgravity and fire prevention, detection, and suppression in crewed exploration spacecrafts and international space station based on NASA's FPDS research program.

화재는 인류가 우주 여행을 하거나 우주에서 체류하고자 할 경우, 특히 조심해서 신경을 써야 할 부분이다. 지구상에서와는 달리, 우주에서는 화재를 피하여 외부로 도망을 칠 수도 없고, 진화를 위해 소방서에 도움을 요청할 수도 없다. 따라서 최선책은 화재를 미연에 방지하는 것이 될 것이다. 그러나, 우주에서는 화재가 발생하였을 때, 그 화염의 행태가 지구상에서와는 다른 양상을 띄게 된다. 그 이유는, 지구상에 있는 모든 물질에 작용하는 중력이 우주에서는 없거나 작기 때문이다. 본 논문에서는 미소 중력하에서의 화염의 행태에 대하여 중요한 부분의 연구 결과를 소개하고, 이에 근거하여 유인 우주 탐사선과 우주 정거장 등에서 화염을 방지, 감지, 진화하는 연구에 대하여 미국 NASA의 FPDS 프로그램을 바탕으로 하여 소개하였다.
