Abstract

A numerical analysis for the internal flow was carried out in order to analyze the leakage flow characteristics inside the damped bypass valve. This research has found that the valve characteristics became stable at above a specific temperature. Very small amount of leakage flow was occurred. But there was no effect in temperature. The more temperature fell, the more maximum pressure rate was increased.

비행조종작동기 제어용 파일럿 밸브의 내부 유동 및 응답 특성을 분석하기 위해 유동의 수치 해석을 수행하였고 내부 누설 특성을 해석하였다. 온도 변화에 따른 누설을 고려한 밸브의 작동온도를 결정할 수 있는 영역을 제안 할 수 있었다. 미량의 작동유체가 누설 영역으로 유출된다는 것을 확인하였으나 누설 효과는 작동 온도에 따라 영향을 미치지 않는 것을 확인하였다. 압력 상승률이 온도가 하강할수록 높아지는 경향을 나타냈다.
