Shrouded Impeller

In December 2018, spin and burst tests of four additively manufactured turbo pump impellers were carried out successfully. Turbopump impellers are highly loaded and highly demanding components used in liquid fuel rocket engines.

Thermochanical test facility

Special non-standard test facilities are developed and manufactured in-house, for thermal mechanical fatigue testing of internally cooled specimens, which represent gas turbine blades for aero engine.

Aerogels

Aerogels are nanostructured, open-porous solids which are synthesized by a sol-gel process. All kinds of aerogels are low density materials, have a low thermal conductivity, possess a large inner surface, are good sound absorbers and can additionally be functionalizedhen.

Mechanical material tests are performed under various loads, which can be uniaxial but also biaxial. Measurements are possible in air, vacuum, and corrosive environments at varying temperature ranges (-196° up to +1,400°C).

The work of the Institute of Materials Research focuses on the development of new materials and the associated process technologies for applications in the aerospace, energy and automotive sectors. In cooperation with other DLR institutes and national and international partners, the Institute carries out both fundamental and applied research. Its research portfolio extends across the areas of metallic structures, hybrid systems and intermetallics, structural and functional ceramics, thermoelectric systems, aerogels and aerogel composites as well as high-temperature and functional coatings.
