핀틀-노즐 밸브의 압력 거동 특성 연구

국문 초록 (Abstract)

고체 추진기관의 추력 조절 방법인 핀틀-노즐 기술을 적용하여 지상연소시험을 수행하였다. 내탄도 성능 예측과 비교하여, 초기 압력은 예측 결과와 유사하였으나 점진적으로 압력이 증가하는 현상이 나타났다. 이는 목면적 감소효과에 기인하는 것으로, 슬래그 침적 및 핀틀의 열팽창 효과에 의해 나타나는 것으로 확인되었다.

Ground burning tests of solid rocket motors were carried out to study the pintle technology, one of the thrust control methods. Comparisons of pressure-time curves obtained by tests with by internal ballistic and performance analysis showed that the measured initial chamber pressure was similar to the predicted one, however, progressive burning was observed thereafter. It was confirmed that the progressive burning was due to the reduction in the nozzle throat area caused by deposition of slag and thermal expansion of the pintle.
