Abstract
A hybrid propulsion unit, for a space vehicle or rocket, includes an external body defining a combustion chamber configured to receive a block of solid propellant, a pressurized reservoir configured to receive a liquid propellant, and a nozzle to eject the combustion gases produced by the reaction of the propellants. The pressurized reservoir being placed inside the external body, surrounded by the block of solid propellant. The propulsion unit further includes a plurality of liquid-propellant injectors disposed axially between parts of the solid propellant to improve the efficacy of the combustion. A space vehicle, of the launch vehicle type, equipped with such hybrid propulsion unit.

Abstract
The present invention relates to a hybrid thruster (100), for a spacecraft or vehicle, comprising an outer body (10), defining a combustion chamber (15) intended for receiving a block of solid propellant (20), a pressurised tank (30) intended for receiving a liquid propellant (40), and a nozzle (50) for ejecting the combustion gases produced by the reaction of the propellants, the pressurised tank being placed inside the outer body, surrounded by the block of solid propellant, the thruster further comprising a plurality of liquid propellant injectors (31) arranged axially between parts of the solid propellant in order to improve combustion efficiency. The invention also relates to a space vehicle, of the booster type, equipped with such a hybrid thruster.
