고속 비행체의 비행궤적별 유로개방장치 동역학 해석 (Dynamic Analysis of a Flow Passage Opening Device in Flight Profile of a High-speed Vehicle)

Abstract : 

       A flow passage opening device utilizing an acceleration follow-up technique allows fuel to flow continuously through a pressurized fuel tank system. It is very difficult to test the device in a real flight situation because of severe test condition and a cost problem. In this paper, therefore, the results of a basic negative g test conducted by low-speed airplane are compared with RecurDyn simulation. Dynamic behavior of the device in total flight profile of a high-speed vehicle is also analyzed by using RecurDyn to predict its performance.
