  "textContent": "An auxiliary propulsion system for a cryotechnic launch vehicle with a main nozzle (1) has a supplementary nozzle (4) connected to the fuel tank (2) via a duct containing a catalytic housing (6) between a downstream end (51) connected to the nozzle and an upstream end (52) connected to the fuel tank (2) and an oxidant tank (3). The two ends of the duct are connected through a heat exchanger (9). The catalyst contains platinum or palladium, the fuel tank contains hydrogen, and the oxidant tank can be the main oxidant tank or an auxiliary one.",
