Stress calculations are necessary to determine the feasibility and profitability of a heat storage tank’s construction. The article presented normative methods of stress calculations for a heat storage tank. Results were verified by finite element analysis. These stress calculations enabled us to determine wall and weld thickness. The calculations were made on the example of a tank with a nominal pressure of 10 bar. The work undertook an extensive analysis of the stresses occurring in a pressure tank, described the finite element method and showed examples of ways in which it could be used. During stress analysis, three types of materials were compared: carbon steel St0 (S185), stainless steel (304) and boiler steel (P 265 GH). A brief overview of types of thermal energy storages was also provided.
The aspects relating to unmanned aircraft and their target acquisition systems are continuously being developed. The subject of the study is a target acquisition system with a thermal camera. A control system is presented consisting of three subsystems. Open- and closed-loop control systems are used. Experimental results unambiguously show that this is a promising line of research and form the basis for further efforts on the topic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
