    1475461 Self-draining liquid storage tanks OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 12 Feb 1975 [21 Feb 1974] 5941/75 Heading B7W A self-draining tank particularly for space craft comprises a casing 11 and a porous body 15 located within the casing and in contact with the inner surface thereof, the body being formed with compartments 19. The dimensions of the compartments and of the pores of the body decrease in the general direction of liquid flow towards the tank outlet 31. In the embodiment shown the pores decrease in size both from the periphery towards the axis 21 and from the end 13 towards the outlet end 14, the outlet comprising a wick 31 sunk into the end of the porous body. The porous body is formed from a nickel or cobalt felt, and a part of the inner surface of the casing may be provided with a porous lining (not shown) in contact with the porous body. A particular liquid to be contained within the tank is caesium.

    (54) SELF-LIQUID BAKDLE FOR LIQUIDS SUPPLIED TO THE ENGINE UNDER CONDITIONS OF WEIGHT
    one
    The device relates to space technology and can be used in the design of the elements of a system for supplying liquid fuel to an engine under conditions of weightlessness.
    The device for supplying liquid from the fuel tank under zero gravity conditions, based on capillary forces. For example, a ciliydric fuel tank is known, in which there is a set of compartments in the form of spherical sectors converging to the axis, and reducing the cross section of the compartments as it approaches the axis promotes the movement of fluid from the periphery to the center, to the drain hole 1.
    However, this tank is difficult to manufacture and does not ensure reliable discharge of fluid from the tank, since the capillary action is comparatively weak.
    A fuel tank is also known, including a ciliatedric shell with a drain hole, inside of which a block of a porous material like a nickel-based felt is placed, with the pore size 2 decreasing in the direction of discharge.
    This tank is heavy, as the porous mass fills the tank shell with a cavity.
    The purpose of the invention is to reduce the weight of 5 tanks and improve the flow of fluid.
    This goal is achieved by the fact that, in a tank containing a cilidric shell with a drain hole, inside of which is placed a block of porous material, on a nickel-base type, with sizes that go in the direction of discharge, in a porous block, longitudinal channels with a cross section are made in the form of circular sectors, angled to the longitudinal pocks of the tank, while the porous material is made of tubular fibers.
    The drawing shows the tank. The tank has a cylindrical shell 1 90 with a drain hole 2, made in the bottom 3, which has a gradually decreasing cross section, and bottom 4. Inside the shell is a block 5 made of porous material and nickel base, in which 25 longitudinal channels 6 with a cross section are made in the form of circular sectors, and angled to the longitudinal axis of the tank 7. A wick 8 of porous material is introduced into the drain hole 2.
    The liquid is drained from the tank under conditions of weightlessness due to capillary forces acting in the direction of narrowing the tubular pores of the porous block 5, while the fuel moves to the drain hole 2 and is fed through the wick 8 to the engine.
