Thermal Testing
- Andreas Mussger (ESA)
A common hardware used by thermal engineers in spaceflight projects are polyimide (Kapton®) and all-polyimide foil electrical resistance heaters. Typical applications range from thermostat-controlled survival heaters, operational heaters, to test heaters (either to simulate internal or external heat dissipation sources, for example radiators).
Same as with any other aerospace hardware, also...
The presentation deals with the thermal testing of a deployable reflector which is part
of a spaceborne SAR payload.
The different challenges, solutions and lessons learnt of the QM thermal vacuum test
will be presented.
Due to the design of the deployable reflector, three different cavities – one external
and two different internal sections – needed to be qualified simultaneously. Due...
The Plato normal front end electronics (N-FEE) unit is an iso-statically mounted structure with high radiative coupling to the telescope cavity. The mechanical mounting consists of thermally isolating Ti6Al4V blades, which result in a high dependency on radiative heat exchange with the telescope to dissipate the heat generated by the PCBs. Previous attempts to correlate the N-FEE thermal model...
