  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
