수소비행체를 위한 수소공급밸브 연구 = A Study on Hydrogen Supply Valve for Hydrogen Aircraft

다국어 초록 (Multilingual Abstract)

Fossil fuel phase-out is a main issue which should be solved for all sector of mobility. Especially for the aviation sector, a hydrogen fuel cell-based aircraft is under development according to its inevitable emission effect and in following to carbon offsetting and reduction scheme for international aviation(CORSIA) by international civil aviation organization. In this study, shape change of hydrogen supply valve has been experimented with flow and magnetic field analysis under aviation running circumstances. Comparing to a normal vehicle driving, aviation is running under different circumstances such as altitude, temperature, pressure and etc. K-epsilon model has been used for the numerical analysis. With redesigning suction force about 10 % and spring constant, it has been improved for hysteresis deviation of hydrogen supply va
