2 Proprietary information statement The technology material presented in this talk is available for licensing or joint product development. None of the slides contain any confidential or proprietary information which would prevent patenting the technology.

3 AEROSPACE ENGINEERING DEMANDS: The creation of perspective space technique has required the long-term and very expensive on- ground investigations and tests. The materials, constructions, devices and vehicles as whole needs routine on-ground tests under simulated condition of outer space environmental factors. As a rule, expenditure for this tests exceed a half of space project cost. For solution of this problems it is necessary to have the array of simulation testing and research equipment, as well as a set of research and measurement methodologies.

4 OUR POSSIBILITIES: Thermo-vacuum testing of space vehicles and its parts (up to 2 m cross section) Investigations of properties of space usage materials under conditions that simulate an action of space environment factors Design and manufacture of simulation testing and research equipment Development and verification of methods for accelerated testing of space technique and materials

Simultaneous irradiations with protons, electrons and ultraviolet beams: electrons energy range: 400 keV to 2 MeV, protons energy range: 40 keV to 350 keV (2,2 MeV option). Ultraviolet radiation ranging from 0,5 to 7 sun obtained from Xenon filtered sources (with infrared and visible rejection). Contamination of sample surfaces with V.C.M. products in controled conditions (in-situ measurements with Quarz Crystal Microbalances). Pressure below 1 10-4 Pa 10-6 torr (Cryogenic pumping units). Temperature range: 50 to 80 C (option: liquid nitrogen temperature). Irradiation zone: 120 mm square surface (25 samples 20 by 20 mm). EQUIPMENT FOR INVESTIGATIONS OF SPACE USAGE MATERIALS
