Refrigerator Freezer Rack (QM)

Prime Contractor EADS Space Transportation - Germany

For the RFR facility DTM was responsible for the design, calculation, manufacturing and integration of the whole structure (CVE - cold volume enclosure) that will have to be accomodated into the rack. The structure is made mainly in glass fibre composite material and partly in aluminium. The CVE is a monolithique 1500 x 950 x 900 mm structure weighing only 150 Kg which has to carry a total mass of about 480 Kg (drawers, cargo, accessories, electronic…) and withstand the huge launch and landing accelerations (equivalent to a force of roughly 1 ton).
