A fiber composite plastic overwrap for a spacecraft container shell (), in particular in connection with spacecraft containers, provides burnup as complete as possible on re-entry into the Earth's atmosphere despite good strength properties and simple production with the aid of conventional fiber winding processes. The overwrap comprises at least one winding tape () of a plastic matrix () in which at least two tape layers () arranged one above the other in a transverse tape direction (y) are embedded. Each of the tape layers () comprises a plurality of fiber bundles () extending unidirectionally in the longitudinal tape direction (x), Fiber bundles () of a tape layer () adjacent in the longitudinal tape direction (x) directly adjoin one another in abutment regions () provided at least once per winding turn, and fiber bundles () adjacent in the transverse tape direction (y) are offset relative to one another in the longitudinal tape direction (x), forming an overlap region ().

A fluid tank for integration into a structure of an unmanned aircraft includes a shell having a first axial wall, an oppositely arranged second axial wall, an upper side, a lower side, and an enclosed interior, at least one receiving chamber in the interior for storing fluid, and a collection chamber, which is arranged on the lower side and which is fluidically connected to the at least one receiving chamber. The collection chamber includes a bottom surface, through which there extends a drain, wherein a covering surface is arranged above the bottom surface and covers at least a portion of the collection chamber. At least one flow opening could be arranged on an upper side of the collection chamber, which flow opening allows gas bubbles to escape in the direction of the upper side of the fluid tank.
