“…The highest velocity occurs at around 40 s, when it reaches a value of slightly over Mach 3. Thereafter, the pressure difference between the two chambers decreases due to pumping, and thus the Mach number gradually decreases (Figure 6) (15,16,17). Figure 6.…”

As a part of the research in the field of pumping vacuum chambers in the Environmental Electron Microscope, a research on supersonic flow through the Appertures is being carried out at the Department of Electrical and Electronic Technology of the Brno University of Technology in cooperation with the Institute of Scientific Instruments of the Czech Academy of Science. This paper deals with the possibility of investigating shock waves using the Shlieren optical method, which allows to observe pressure gradients as the first derivation of pressure.

“…Many studies have focused on laminated glass, which has a polymer layer sandwiched between glass plates [8][9][10][11]. Several researchers have built and analysed finite element method (FEM) models that include the failure modes of laminated glass and proposed methods to prevent failure [12][13][14][15]. Ge et al [6] investigated fragment projection velocity for architectural glass panels that fail under blast loads to predict fragment flight paths.…”

“…Hidallana-Gamage et al [7,13] built an FEM model of laminated glass panels that fail under blast loading and examined their design criteria. Binar et al [12] built an FEM model for each layer of multi-layered transparent armour glass to reproduce the fracture response due to the high-velocity impact of a bullet. Müller-Braun et al [8] experimentally investigated the differences in strength, and thus the distribution of microdefects, in various areas of a laminated windscreen.…”

“…Sukac et al [2] in their work have dealt with the impact of climatic conditions, temperature and relative air humidity on the occurrence of material corrosion with consequent influence on the military unit economics. Other research projects investigating the influence of temperature on military material were presented in the literature [3,4]. The properties of military clothing significantly affect the properties of the materials from which they are made.…”

This study presents methods for measuring thermal insulation of military clothing assemblies used in various climatic regions of the world, with the exception of polar regions. With the use of FOX 314 and thermal manikin, the thermal insulation of the fabrics (military materials) was ascertained at simulating real climatic conditions of cold, arid, temperate and tropical zones according to European standard EN 60721-2-1: 2014. The aim of this study was to compare the values of thermal insulation of the duty of military clothing ascertained by two methods and to evaluate the reliability of methods and instruments used. The measured results show that the measurement methods used are different in terms of method and measurement conditions, the results of the thermal insulation and the resulting choice of military clothing in the type of climate. The functionality and suitability of the use of military clothing sets were verified in real climatic conditions, provided that the optimal thermal comfort of the wearer was achieved.
