ABSTRACT:
The surface tension tank is designed to feed a liquid propellant to a main engine and to at least one auxiliary engine or receiver of a space vehicle or satellite. The tank comprises a common shell containing at least two compartments of different sizes that are separated by a diaphragm provided with at least one strainer for providing communication between the large compartment and the small compartment. A pressurization gas feed orifice opens out into the large compartment. A liquid expulsion device is placed in the small compartment, and means for delivering liquid to the members to be fed are essentially disposed along a direction that differs little from the direction of the main acceleration imparted by the main engine, in such a direction as to accelerate liquid flow therealong. Means provided with at least one outlet strainer constitute a gas barrier and are provided for removing at least a substantial fraction of the liquid contained in the large compartment directly to the liquid delivery means without the liquid transitting through the small compartment, such that the tank makes it possible to obtain a maximum liquid outlet flow rate that may be about 100 times the minimum authorized flow rate.
