Abstract:
An autogenous pressurizer device for a main propellant tank, the device includes a pressurizer pipe connected to the main tank to inject propellant into the main tank, a pressurizer valve arranged on the pressurizer pipe, and a heater for heating the propellant upstream from the pressurizer valve. The pressurizer device includes a buffer tank connected to the pressurizer pipe upstream from the pressurizer valve.
Abstract:
A feed device (20) for feeding propellant to at least one rocket engine propulsion chamber (19) of a propulsion assembly (21) comprises a main propellant tank (1, 2), and a main feed pipe (3, 4) extending between the main tank (1, 2) and the propulsion chamber (19) and having a main feed valve (VAH, VAO) placed thereon. The feed device further comprises an auxiliary tank (11, 12) for said propellant and an auxiliary feed pipe (13, 14) provided with an auxiliary feed valve (VH1, VO1) connecting the auxiliary tank (11, 12) to the main feed pipe (3, 4) downstream from the main feed valve (VAH, VAO).
