[0002] During the propellant loading process (mainly fuel and oxidizer) of a liquid rocket before launch, the propellant needs to be transported from the storage container to the rocket's engine via a loading hose. The loading hose is typically a corrugated hose with a diameter of 50mm or 100mm, and its length is determined by the distance between the loading system and the rocket. In the design of loading systems at space launch sites, the length of the loading hose is generally between several meters and tens of meters.
