According to the invention, after a tank (18) is filled with liquid oxygen (20) to be used to supply a rocket engine (10) with fuel, but before the engine (10) is operated, the tank is pressurized by injecting gaseous nitrogen (N) therein. During the operation of the engine (10), liquid oxygen (20) is collected and heated such as to obtain gaseous oxygen, and the gaseous oxygen is injected into the vapor space (42) of the tank, the pre-pressurization nitrogen forming a nitrogen buffer (40) between the liquid oxygen present in the tank and the gaseous oxygen injected into the vapor space. |
