This work deals with the application of new approaches to welding production of modern light, strong, and heat-resistant metal composite materials in aeronautical and space technology. The objective of this article is to substantiate introduction of modern technology for welding composites in production, namely the development of argon-arc welding technology and the choice of equipment when using composites of the Al-B system for manufacturing the flame tube of the combustion chamber of an aircraft engine. Based on the study of technical literature and scientific publications, a short analysis of the existing technological processes for welding heat-resistant glass-ceramic composites was carried out. The problems arising in the process of welding aluminum composites reinforced with boron and steel fibers are considered. A modern gas tungsten arc welding based on new technological processes is offered with an example of welding in manufacturing a combustion chamber of a modern gas turbine modified engine.
It is shown that failures at normal operation of pipeline transport occur largely due to the cyclical nature of degradation processes that are inherent in the system with various soil and swamp covers and are accompanied by sharp negative temperature gradients. A model of methane liberation processes was generated. The method of molecular beam epitaxy was analyzed, which permitted to capture the volume and cyclicity of methane liberation, to measure all noises and signals in different frequency ranges.
The development of environmentally friendly technology for the construction of non-rigid roads and systems for laying pipelines on block elements from composite pontoon modules in swampy and waterlogged areas for the Far North and Siberia is presented.
Abstract. When operating underground storage (UGS) of gas hydrates liquidation formed untimely could lead to serious consequences -a complete shut-in and elimination of its process. With a small fund operating wells with high daily output storage operation would entail a violation of technological regime, the failure of gas sales plans, increased hours of downtime operational fund. Therefore, ensuring the smooth and reliable operation of underground gas storage wells fund is an urgent task. The authors of the article developed a methodology for calculating the operational flow of methanol to prevent the formation of gas hydrates in UGS operation. On the basis of the developed technique using industrial operating data Punginskoye UGS made the study of technological modes of its work and recommendations to prevent hydrate formation in the underground gas storage wells.
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.
