Abstract

A special part such as a flow passage opening device is required to prevent the disconnection of fuel transfer in a pressurized fuel tank. To meet this requirement, the device utilizing an acceleration follow-up technique was invented. RecurDyn, a dynamic analysis tool, is introduced in this article to predict the device's performance and to determine parameters affecting it. In the analysis, it is shown that balancing weights can open the passage in accordance with fuel position.

항공기 또는 유도무기와 같은 고속 비행체의 가압식 연료탱크에는 연료가 한 방향으로 몰려 이송이 단절되는 것을 방지하기 위해 특별한 유로개방장치가 필요하다. 이러한 필요에 의해 가속도추종 방식의 유로개방장치가 발명되었으며 본 논문에서는 이 장치의 구동성능을 예측하고 성능에 영향을 미치는 주요 파라미터의 선정을 위해 동역학 해석 프로그램인 RecurDyn을 이용해 해석을 수행하였다. 해석결과를 통해 장치의 내부 균형추가 연료의 쏠림을 잘 추종해 유로를 개방시키는 것을 확인하였다.
