FIELD: engines and pumps.
SUBSTANCE: invention relates to a system for feeding rocket fuel to a rocket engine (2) comprising a first tank (3), a second tank (4), a first power supply system (6) connected to the first tank (3), and a second power supply system (7) connected to the second tank (4). For cooling the rocket fuel contained in the second tank (4), the first power supply system (6) includes a branch (12) passing through a first heat exchanger (14) built in the second tank (4). The invention also relates to a method of feeding rocket fuel to the rocket engine (2).
EFFECT: maintaining pressure in the tanks above the minimum limit.
