ACTOR project from RWTH Aachen
Students test aerogels in space
Students from the RWTH University in Aachen took part in an international project organised by the DLR National Aeronautics and Space Research Centre of the Federal Republic of Germany and the European Space Agency (ESA).
The project named ACTOR (Aerogel Cells Tested on REXUS) is part of the student space program REXUS/BEXUS where students from various universities in Europe have the opportunity to develop and conduct scientific and technological experiments on a rocket for space flight.
As part of the ACTOR project, students tested aerogels that they had developed at the RWTH University for their insulation properties and their suitability for use in space.
The project is based on these designed aerogels (stable, open, porous material that exhibits excellent heat insulation) which are manufactured from cellulose. This material allows the innovative production of fibres and fabrics for spacesuits or flexible insulation material on hoses.
The aerogels were fitted in test cells for the flight into space. The temperature between the inside of the test cells and the environment was measured during the flight.

The REXUS 18 rocket was launched on March 18, 2015 from the rocket launch pad of the Swedish Space Agency SNSB. The flight was successful for the team who were able to measure all the required data.

norelem in the project:
To ensure that the test cells could withstand the vibrations and shocks during the rocket's flight, a safety mechanism was designed which requires plates springs for a pretensioning force. The same mechanism is used to attach the camera onboard.
