A fuel tank pressurization system of a propulsion system with a pressurized gas, such as helium, comprises tanks with drainage and safety valves, high pressure pumps, cylinders for compressed helium and automatic units, which are connected by a main line of pressurization to the free volume of the tank, while the cylinders with compressed helium are placed outside the tank with liquid oxygen in the tail section, in a special container, which is provided with thermal insulation, a drain valve, a level gauge, a fill-discharge valve of coolant. The cylinders with compressed helium are placed outside the tank of liquid oxygen in the tail section, in a special container, which is provided with a thermal insulation, a drainage valve, a level sensor, a fill-discharge valve of coolant, an ejector, wherein the bottom protection and container bottom have the inserts of a material, which transmits thermal radiation (primarily infrared radiation), while the inserts of the container and bottom protection are arranged coaxially both opposite each other and with the cylinders. |
