Abstract :
In order to survive reentry, the Hermes spaceplane is covered with a thermal protection system (TPS). In areas where antennas are located, two types are used: shingles in the hottest areas. and a flexible mattress in the less hot ones. The shingle TPS consists of C/SiC composite boxes filled with internal multiscreen insulator. The shingles are fixed to the aluminum spaceframe. The shingle antennas are integrated in the center of a shingle. Two concepts have been developed: a waveguide antenna and a patch cavity antenna. High-temperature tests have been performed on both concepts. In the tests the antennas were exposed to a thermal environment representative of an atmospheric reentry.<>
