Space Simulation Facility

Closed space simulation facility in test operation
In the large-scale facility of the DLR Institute of Space Systems, Navigation and Control Systems in Bremen, both individual components and complete systems of space applications are subjected to a thermal vacuum test. The aim is to accompany design processes for space components and thermal control systems.

The space simulation facility conducts thermal vacuum testing of both individual components and overall systems for space applications.

Environmental conditions that will be encountered later in the space mission, such as high vacuum, the cold temperature in space, the temperatures around other celestial bodies and solar radiation, can all be recreated during these simulations. Using a special test setup the facility can be used to study the venting behaviour of structures during launch.

The aim of the thermal vacuum test is to support the process of designing space components and thermal control systems, their qualification and the verification of numerical thermal models.

The solar simulation chamber is accredited as a testing laboratory in accordance with DIN EN ISO/IEC 17025:2005 and fulfils the clean room requirements of ISO-8 in accordance with Standard ISO 14644-1.

Service range

  • Thermal balance test: is a thermal vacuum test in which the thermal balance and the corresponding temperature distribution are of interest
  • In-thermal cycling tests – the functionality of the test object is examined using a predetermined number of cycles under certain temperatures (environmental conditions).
  • Quick air venting
  • Support during developmental tests
