Study of thermal effects of electromagnetic radiation on the environment from space rocket activity

Abstract

The article presents the results of a study of electromagnetic effects from space rocket activity using the example of the Plesetsk cosmodrome and aviation complex using the example of Ostafyevo Airport. The influence of electromagnetic pollution on the environment is considered; the authors analyze the influence of electromagnetic fields on human health taking into account thermal effects. It was demonstrated that the long-term effect of electromagnetic sources with different wavelengths at moderate intensity causes changes in the irritability of visual, olfactory and vestibular analyzers, as well as development of functional disorders in the nervous system without pronounced changes in endocrine-metabolic processes and blood composition, also trophic disturbance might be present. The authors study in detail the main anthropogenic sources of electromagnetic effects from objects of rocket and space, and aviation activities.

Effect of High Velocity Deformation on Strength of ArmoredComposite Materials

“…The volumetric content of fibers was 60%, the diameter of the fibers was 5 μm. Samples of three types were considered: 1) a quasi-homogeneous layered composite with a unidirectional reinforcement scheme, 2) a unidirectional composite with a wavelike layered structure, and 3) a pure matrix [26][27][28][29][30][31][32][33][34][35][36][37].…”

Creation of Polymer Coatings for Improving of Protective Properties of Surfaces

“…From the point of view of strength calculations, thin-walled metal structural elements with polymer coatings can be presented in the form of two-or three-layer plates (depending on whether the coating is applied on one or both sides) with a tougher metal middle layer and much more pliable outer layers-coatings [25][26][27]. Currently, not many experimental and theoretical works are known in which the analysis of the macroscopic mechanical behavior of such structural elements is carried out taking into account the effects of the influence of residual stresses [28][29][30].…”

“…Currently, not many experimental and theoretical works are known in which the analysis of the macroscopic mechanical behavior of such structural elements is carried out taking into account the effects of the influence of residual stresses [28][29][30]. It is possible to note a wide variety of works in the field of research of functional-gradient thinwalled structures with coatings (see, for example, [26][27][28] and references therein). However, in such structures it is usually assumed that the rigidity of the surface layers is higher than that of the inner region.…”

Effect of Shape of Armoring Fibers on Strength of Composite Materials

“…Currently, a large number of studies have been carried out to obtain and study the strength of composite materials [1][2][3][4][5][6][7][8][9]. A large amount of experimental data dedicated to the synthesis and exploration of heterophase composites were obtained [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”
