Turbine Engineering in Ukraine in the 1940s–1970s: Yakiv Isidorovych Shneie

Abstract

The article highlights the scientific, technical, pedagogical, and organizational activities of Yakiv Shneie, an outstanding scientist, Doctor of Technical Sciences, professor, and specialist in the field of turbomachinery. It provides a detailed analysis of his contributions to the development of the Department of Turbomachinery at Kharkiv Polytechnic Institute (KhPI), the organization of the educational process, the advancement of experimental research, the creation of new educational programs, and the training of highly qualified specialists in the field of steam and gas turbines. The separate section examines his work on improving steam turbines, which became crucial for the development of the energy sector in the post-war period. Under his leadership, there was a large-scale transition from 50 MW turbines to 500 MW units, which were used in both thermal and nuclear power plants. Thanks to the department’s collaboration with the Kharkiv Turbine Plant, Ya. Shneie’s scientific developments found practical application in production, contributing to the modernization of equipment and increasing turbine efficiency. The article explores Professor Ya. Shneie’s role in establishing a specialized research laboratory and an industry-focused laboratory dedicated to gas dynamics, heat exchange, and optimization of gas turbine cycles. Under his guidance, modern cooling methods for hot turbine components were developed, the aerodynamics of blade assemblies were improved, and experimental research was conducted under conditions close to real-world applications. The significant achievement was the establishment of a specialized academic council at KhPI, where dissertations on turbomachinery, steam generator engineering, and hydraulic machine engineering were defended. Professor Shneie personally supervised 35 Ph.D. dissertations, and seven of his students later became Doctors of Technical Sciences. His scientific legacy includes more than 100 research publications, including seven monographs, which have become important resources for scientists and specialists in power engineering and mechanical engineering.

His contributions were recognized through participation in the Scientific and Technical Council of the USSR Ministry of Heavy, Energy, and Transport Engineering, as well as in the Gas Turbine Commission of the USSR Academy of Sciences. The scientific school founded by Professor Ya. Shneie made a significant contribution to the global development of turbomachinery, and his work strengthened the position of Ukrainian science in the field of energy engineering. The research conducted in this article is based on archival materials, publications and documents that reveal key aspects of the scientist's work.
