Vývoj teplotně-vakuové komory pro testování palubních a kosmických zařízení v simulovaných extrémních podmínkách

Thermo-vacuum test chamber development for airborne and space equipment testing in simulated extreme conditions

The Institute of Aerospace Engineering, Brno University of Technology developed a unique thermo-vacuum test facility to simulate extreme aerospace environmental conditions. Even though originally developed for space technology Qualification tests, the know-how can be used to test airborne equipment in laboratory to develop and certify new prototypes under civil or military aviation regulations. Moreover, the experimental thermo-vacuum chamber can be used for research and development of space technologies and its testing in different simulated space environments. The innovative tailor-made thermo-vacuum chamber presented here was designed to enable test procedures in simulated Martian atmospheric conditions (vacuum of 50 Pa absolute, temperatures up to −125 °C and pure CO2 environment of 1000 Pa absolute). The vacuum tightness of the chamber, the deep cooling of the tested sample under a vacuum environment, the thermal insulations or the heat transfer paths had to be precisely considered. The verification tests of the facility design then proved excellent performance and viability for future technology modifications. This paper reflects the market needs to test airborne and space equipment in different vacuum-cryogenic and thermally controlled extreme conditions.
