Lightweight Structures for Space Applications

In-Situ investigation of ablative heat shield materials
In order to protect spacecraft from the extremely high temperatures apparent during atmospheric entry, ablative heat shields are being deployed. These thermal protection systems are based on the controlled decomposition of the heat shield materials, with processes like charring and melting. To obtain a better understanding of these ablation processes, miniaturized facilities were developed in order to investigate ablation processes in-situ utilizing synchrotron x-ray tomography.

The test stand INDUTHERM is intended for the thermal and mechanical testing of structural components such as load introductions. Heating of the test specimens takes place inductively by a susceptor tube that produces a homogeneous temperature field in its interior.

Lightweight. Reliable. Temperature-Resistant.

The research field 'Lightweight Structures for Space Applications' has a clear focus: to consider the whole system in order to find new solutions for every detail. Spaceflight places many diverse demands on structural systems; they have to be light, reliable and above all resistant to thermal loads of between -250 °C and +2000 °C.

Every day, this research group deals with the whole process chain from the materials through to airworthy prototypes. Their work mainly focuses on the use of fibre-reinforced plastics and ceramics, while integrating production methods and technologies into design and simulation processes. Digitalisation opens up possibilities for generating an increasing number of unconventional and innovative system solutions. The latest, flexibly configurable mechanical and thermal test equipment is used for verification purposes, supplemented by access to flight tests in realistic conditions.

A special feature of this research field is the development of innovative approaches for the cost-efficient development and construction of highly integrated commercial satellite systems, creating new standards in this area in cooperation with industry and university partners time and again.
