Spatial correlation for transmitters in MIMO optic communication
Pressurization system is very important in a flight vehicle propulsion system. Using the normal temperature gaseous helium to pressurize is one of the important means in propellant tank pressurization system of liquid propellant rocket engine. The regular operation of pressurization system ensures propellant supplying steadily and the engine operating normally. But in the fast and transient priming process of high-pressure gaseous helium, the unsteady gas flow is likely to cause unsteady pressue, consequently brings on violent vibrations of the whole gas pipeline system, which can seriously destroy the structure of the system and make the pressurization system invalid. Therefore the study on the transient priming process of high-pressure gaseous helium in pressurizing gas pipeline system of a launch vehicle is significant.
