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.

Turbine inside volcanic ash test rig

The test rig and its mea­sure­ment equip­ment are used to in­ves­ti­gate, how vol­canic ash acts on air­craft tur­bines.

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.

Materials research test hall

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.
