Abstract: The invention relates to the field of rocket engines, and more particularly to a propulsion assembly (10) comprising a first tank (11) for a first liquid propellant, a second tank (12) for a second liquid propellant, a pressurizer device (60) configured to maintain a substantially higher pressure in the second tank (12) than in the first tank (11), and a single-shaft turbopump (30) comprising a turbine (33), a first pump (31), and a second pump (32). The turbine (33) is actuated by expansion of the first propellant after it has passed through a regenerative heat exchanger (44), and in turn it acts via the single rotary shaft (34) of the turbopump (30) to drive said first and second pumps (31, 32) respectively pumping said first and second propellants in order to feed a propulsion chamber (40).

Abstract: The invention relates to a device and a method for feeding a propulsion chamber 5 of a rocket engine 1 with at least with a first propellant. The device comprises at least a first tank 2 for containing said first propellant, a first feed circuit 4 connected to the first tank 2, and a first electric pump 10 within said first tank 2 in order to pump said first propellant through the first feed circuit 4. In the method, the first propellant is pumped through the first feed circuit 4 from the first tank 2 by at least said first electric pump 10 that is immersed in the first propellant within the first tank 2.
