Abstract: A supply system for supplying a rocket engine with at least one propellant, the supply system comprising at least one supply circuit able to circulate the propellant, and at least one reservoir in fluid communication with the supply circuit via at least one communication pipe, so that a fluid contained in the reservoir can flow from the latter up to the supply circuit, and vice versa, via said at least one communication pipe, the reservoir being able to contain a volume of gas, and heating means able to vary the volume of gas in the reservoir, the heating means being configured to vaporize the propellant in the reservoir.

Abstract: A pogo effect corrector system for a liquid propellant feed system of a rocket engine includes a liquid propellant feed pipe portion, and a hydraulic accumulator including a tank connected firstly to the feed pipe portion firstly via at least one take-off passage opening out into a take-off segment of the feed pipe portion, and secondly via at least one rejection passage opening out into the tank at an intermediate level lying between the at least one take-off passage and the top of the tank, wherein the feed pipe portion possesses a constriction segment where the flow section of the feed pipeline portion is less than the flow section of the take-off segment, and wherein at least one rejection passage opens out into the feed pipeline portion in the constriction segment.
