A composite tank for a reusable launch vehicle comprises a composite wall, having a first coefficient of thermal expansion. The composite wall comprises a first end, a second end, a central axis, which passes through the first end and through the second end, and a cylindrical interior surface. The composite tank also comprises slosh baffles, formed from a second material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. Each of the slosh baffles is attached to the cylindrical interior surface of the composite wall. Each of the slosh baffles is annular and is separated from the cylindrical interior surface of the composite wall by a radial gap, selected, in part, based on a difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion. The radial gap is configured to change responsive to changes in temperature of the composite tank.

Composite tanks for reusable launch vehicles and methods of fabricating thereof

A fuel tank comprises an interior wall, a sump, and a baffle that comprises a center fitting, a full-length containment petal, a partial-length containment petal, a dump tube. The full-length containment petal comprises a full-length side edge, extending radially outward from the center fitting. The partial-length containment petal comprises a partial-length side edge, extending radially outward from the center fitting. The dump tube is connected to the sump. The full-length side edge of the full-length containment petal is longer than the partial-length side edge of the partial-length containment petal. All of the partial-length side edge of the partial-length containment petal is attached to a linear portion of the full-length side edge of the full-length containment petal.
