- W2138251013 abstract "고온/고압, 장시간 연소조건에서 비삭마에 가까운 삭마 특성을 갖는 초소형 목삽입재 선정을 위한 연구를 수행하였다. 평가 소재로서 C/SiC, CIT, W/<TEX>$Y_2O_3$</TEX>를 선정하였으며, 연소시간 20초의 내열성능평가모타로 시험하였다. 시험 결과 W/<TEX>$Y_2O_3$</TEX>가 가장 우수하였으나, 균열이 발생하였다. 본 연구를 통하여 각 소재들의 열반응 특성 및 내열 성능을 이해할 수 있었으며, W/<TEX>$Y_2O_3$</TEX>의 적용가능성을 확인하였다. This paper describes the research on the non-eroding throat insert materials under condition of high-temperature, high-pressure, and long-burn time. C/SiC, CIT and W/<TEX>$Y_2O_3$</TEX> were chosen and tested in thermal protection evaluation motor of burning time 20 seconds. From the test results, a heat resistance of W/<TEX>$Y_2O_3$</TEX> was the most excellent among them, but was happened crack on material surface. Thermal reaction characteristics and heat resistance of these materials and feasibility of W/<TEX>$Y_2O_3$</TEX> as throat material were ascertained." @default.
