Abstract
A tank for propellant in a space vehicle includes a trap defined by two walls which are substantially permeable to liquid but not to vapour. One wall (16) allows liquid to flow into the trap. The other (7,8) allows liquid to flow out via an outlet port. Vapour in the trap escapes via a vent (19,20). The wall (16) which allows liquid to flow to the outlet include a plurality of plates (1) clamped together. The surfaces (9) of the plates (1) are grooved such that plate surfaces engage to form fine passages (10) permeable to liquid but not vapour.
