Abstract: The article considers the current state and the main promising areas of scientific and practi-cal developments in the field of radio electronics. For the space application of mechatronic systems, the microcircuits are characterized by multi-nomenclature low-volume indicators. To create a high-ly reliable electronic component base, it is necessary to ensure resistance to the fields of ionizing radiation from space, a wide range of temperatures and mechanical stresses. This requires the crea-tion of ECBs for spa… Show more

The paper considers the processes occurring during the absorption of ionizing radiation energy. The task of developing mathematical models for determining the temperature of layers of a multilayer structure due to radiation absorption, the appearance of compression and tensile stresses, as well as tension associated with thermal expansion of the structure is set. It is assumed that the radiation energy is absorbed entirely in the beginning for a short period of time, and then it is redistributed across the layers. Each layer of the structure has its own initial and boundary conditions. Thus, the definition of a complex temperature profile is considered as the sum of some temperature profiles for simple problems solved analytically. The occurrence of stress in the structure is described by calculating the maximum value of the compression stress, the amplitude of the stress wave, as a result of which the expansion of materials can be observed. According to the proposed mathematical models, calculations of thermal and thermomechanical effects in a multilayer structure were carried out, the results of which are illustrated in the article by graphs of temperature distribution after exposure to ionization radiation, and stresses for different proportions of the thickness of the structure to its length.

The article analyzes theoretical and practical aspects of affecting nuclear explosions conducted in outer space. The study begins with a review of historical experiments and continues with assessing the technological, physical, and environmental consequences of such explosions. The paper pays particular attention to the effects of electromagnetic pulses, changes in the Earth’s ionosphere and magnetosphere, and the potential impact on satellite systems and spacecraft. The limitations associated with using nuclear weapons in space and potential scenarios for employing such technologies in the future for national defence and protection are considered.
