PROPELLANT TANK WITH ON-OFF CONTROL SYSTEM FOR THE FLOW OF PROPELLANT GAS AND SPACECRAFT INCORPORATING SUCH A CONTROL SYSTEM

摘要

The invention concerns a solid or liquid propellant (2) tank (1) for propellant, the tank (1) comprising means for forming a gas (9) in the tank, the tank (1) having an opening (4) of area S for extracting a flow (20) of propellant gas from the reservoir (1). According to the invention, the reservoir (1) comprises an on-off control system for the flow of propellant gas comprising a grid (6) arranged opposite the opening (4) of the tank (1), a first thermal regulation system (11, 21) capable of heating the gas (9) in the reservoir and a second thermal regulation system (12, 22) capable of heating the grid (6), the grid (6) comprising holes of total area greater than the area S of the opening of the tank (1).
