    摘要: A thermal protection system suitable as a heat shield for a space vehicle includes a flexible insulation mat that is adhesively bonded onto the outer skin of the space vehicle, a cover layer made of at least one ply of a ceramic fiber composite material secured onto the insulation mat, and a coating of an inorganic material applied onto an outer surface of the ceramic cover layer. The cover layer is secured to the insulation mat by adhesive bonding, stitching with ceramic threads or the like, or by a snap fastener button connection. The ceramic fiber composite materials of the cover layer include inorganic fibers which are preferably oxides, carbides or mixtures thereof embedded in a matrix of the same compositional components, whereby the components can be selected appropriately depending on the requirements of the particular application. The overall thermal protection system remains flexible, lightweight, and highly effective for thermal shielding, so that it may be used not only on the relatively cooler portions of the space vehicle, but also on the most highly thermally loaded areas such as the nose and the leading edges of wings and the like.

    摘要: Within a cell-oriented communication network, a switching equipment (CCa) located at the start of a path pair duplicates a message cell stream supplied thereto for redirection. The message cell streams resulting therefrom are separately supplied to a switching equipment (CCb) located at the end of the path pair via an active path (AP) and via an alternate path (EP) of the path pair allocated thereto. A decentralized synchronization means (SY) or, respectively, a plurality of decentralized synchronization means (SY1, SY2 or, respectively, SY3, SY4) is or, respectively, are provided therein, a synchronization of the two message cell streams ensuing therein while initially forwarding the message cell stream of the active path. After such a synchronization, only the message cell stream of the alternate path is then forwarded.
