| Abstract: | A high-pressure and low-temperature storage tank was designed,which can be used to obtain and store 20 K@35 MPa cold helium gas coupling with Stirling refrigerator.It has liquid hydrogen temperature test capability without using liquid hydrogen,so as to meet the gas source requirements of cold helium pressurization system experiment for rocket.The heat leakage analysis of the tank was carried out.Solidworks and Matlab were used to simulate and calculate the pre-cooling process and heat transfer process.The pro-cooling and heat transfer time are found to be 3 hours and 47 hours respectively. |
