摘要
The invention concerns a tank (10) for a two-phase cold gas propulsion system of a space craft comprising a microporous structure (3) capable of ensuring, in a part of the tank (10) which opposite to an orifice (4) discharging gas outside the tank (10), capillary retention in liquid phase of a two-phase fluid contained in the tank (10). A device for thermal control of the tank (10) comprises at least one heater (2) associated with the part of the tank (10) containing the gas phase, as well as a thermistor (5) in said part, and at least one other thermistor (6) in the part of the tank (6) containing the microporous structure (3) and the liquid phase. The mechanical structure (1) of the tank (10) is mounted on the structure of the space craft through a rigidly mounted interface (7) and a flexibly mounted interface (8). The invention is useful in particular for equipping satellites weighing some tenths to some hundreds of kilograms.
