Отдел надежности и динамической прочности

    The department was created in 1957. Since its creation and to 1991, the department's Head was Academician NAS of Ukraine L.A.Shubenko-Shubin, a renown designer and outstanding scientist in power engineering and power steam and gas turbine building, USSR State Prize Winner , and Hero of Socialist Labor. The key departmental research staff was trained in the scientific school headed by Academician L.A.Shubenko-Shubin. The traditional research area, founded by L.A.Shubenko-Shubin and maintained by his progeny, can be generally stated as follows: "The theory and practice of developing and improving power machinery and installations by mathematical modeling methods and tools and full-scale computational experiment". Since 1974, Academician L.A.Shubenko-Shubin initiated the regular holding first of republican and then All-Union conferences, and since 1994, international conferences "Improving turbine installations using mathematical and physical modeling methods". The results of basic and applied research are presented in over 1,200 papers, including 30 monographs. Currently, the Department is staffed with 14 persons, including 1 Doc. Sci. and 6 Candidates of Science.
