Space environment simulator

Description

Cryogenic and aerospace equipment is exploited in complicated and unfavorable environmental conditions caused by Solar irradiation, high-power flux of corpuscular irradiation from radiation belts of Earth, vacuum, zero-gravity, low temperatures, significant cyclic gradient thermal loading, notable static, dynamic and reciprocal cyclic loadings, vibration etc. Each of the mentioned factors influences alteration of mechanical, optical, electric, thermo-physical, tribotechnical and other properties of materials used in the equipment, whereas cumulative impact of all these factors is not additive.

Today, therefore, the main tasks of cryogenic and aerospace materials science are: determination of serviceability, reliability and lifetime of existing materials as well as creation of novel materials with enhanced characteristics. Such factors as non-uniformity of in-flight heating of different portions of Space vehicle (SV), time-dependent alteration of adsorption coefficients and degree of darkness for outer surfaces of SV, with account of inner energy dissipation – require special and sometimes very intricate experimental studies. It is expedient that the experiments are run at onground elaboration of spacecraft and involve special facilities simulating Space environment conditions.

In order to solve the abovementioned problems, experts of Special Research and Development Bureau (CRDB) for Cryogenic Technologies of B. Verkin Institute for Low Temperature Physics and Engineering at National Academy of Sciences of Ukraine (SRDB) have elaborated methods, equipment and technologies for creation of special purpose simulators series.

Specialists of the SRDB have a great experience in development of simulation equipment. Earlier they built more than 10 complete sets of Simulators (Fig. 1, Fig. 2) for commercial purposes, as well as for researches in the field of materials science and SV testing in Germany, China, for National Space Agency of Ukraine, "Yuzhnoye" Design Bureau, Ukraine, etc.

Personnel of the SRDB includes, particularly, a team of experts capable of solving a wide range of materials science tasks, specialists in the area of design and technology engineering, a group of young scientists and experts.

Innovative Aspect and Main Advantages

We are seeking collaboration for development of a cooling machine which would be installed in the cooling equipment of Simulators. Such modification of Simulators would allow to use them without cryogenic liquid and to expand, therefore, application in the aerospace industry.

Areas of Application

The complex simulation equipment is intended for simulation of space vacuum, cold Space environment, fluxes of protons and electrons, electromagnetic radiation by the Sun and Earth, and Earth-albedo with the purpose to study the influence of these factors on thermal regime of hardware and instruments of SV, as well as to determine serviceability, reliability and lifetime of cryogenic and other materials used in aerospace.
