Way transfer of gelling propellant

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing the blockage of a transfer pipe in pressure transferring a gelled propellant from one tank through a transfer pipe to the other tank. ;SOLUTION: When a gelled propellant for which liquid propellant is gelled by adding gelling agent is pressure transferred from a tank 1 through a transfer pipe 3 to a tank 2, inner pressure in the tank 2 is set to be not less than liquefying pressure of the liquid propellant and inner pressure in the tank 1 is set to be greater than the inner pressure in the tank 2.;COPYRIGHT: (C)2001,JPO
