FUEL TANK Russian patent published in 2007 - IPC B60K15/03 B64G1/22 B64D37/06 

FIELD: aerospace engineering.

SUBSTANCE: invention relates to fuel tanks of spacecraft operating at zero-G and when changing from zero-G to G-loads. Proposed fuel tank has housing with intake and drain holes and cross partition hermetically fastened on housing walls. Partition is depressed in direction of intake hole, and hole with permeable element is made in its central part. According to invention, in peripheral part of said partition additional holes are made with fitted-in permeable elements. All permeable elements are made in form of capillary-porous elements of foamed metal based on corrosion-resistant metal or alloy. Capillary-porous element of central hole is arranged in cylindrical shell. The latter has solid base in lower part pointed to intake hole, and is provided with side ports at this base. Partition can be arranged in area of intake hole.

EFFECT: provision of stable repeated starting of engine plant of spacecraft at zero-G, reduced weight of fuel tank.
