“…In our country there is a fairly large practical experience in the design, production and testing of large-size space structures, allowing to take into account the features of the thermal regime in the implementation of the project of the transformable space debris catcher [9][10][11][12][13][14].…”

“…Also, the products quality can be improved through increase of the temperature fields' uniformity in workpieces. It is expected that this technology will be more effective at manufacturing of the master parts of the composite structures (for instance, force rods of the flexible space reflectors, trusses and solar panels [14][15][16][17][18][19][20]).…”

The simulation results of the thermal state of a cylindrical workpiece made of composite material and exposed to the action of microwave radiation are presented. The mathematical model of a workpiece allows the analysis of the interconnected thermal and electromagnetic processes in the equipment operating area, and also takes into account the exothermic effect associated with the curing of the polymer matrix.

“…Promising avenues for the development of communication systems and systems for remote sensing of the Earth include the creation of spacecrafts with transformable antenna reflectors. [1][2][3][4]. Antennas with large reflectors «AstroMesh» (rim structure) are used in space communication satellites «Thuraya», «MBCO», «Inmarsat», «GlobalStar».…”

Currently, the task of designing large structures of space antennas is becoming increasingly important due to active research and development in the area of creating remote sensing and communication satellites. Designing such structures is a complicated task due to geometric features, a large number of joints, compactness requirements, as well as operating conditions of the outer space. These factors require special methods for assessing the workability of these structures. This paper presents the results of simulation and experimental studies aimed at creating transformable antenna reflectors. The results of choosing general structural layouts are considered. It is noted that the main reason for the reflector shape distortion is non-uniform heating by the solar radiation and radiation fluxes coming from the Earth. The paper presents the results of numerical modeling of temperature and stress-strain state of transformable antenna reflectors from metallic mesh sheet meeting the requirements for operating on the geostationary orbit.
