Samara University Repository
Welcome to the Samara University repository!
This is an open electronic archive created to preserve and disseminate the scientific results of our university. The works of researchers, faculty members, and students are available to everyone for academic and research purposes.
The repository contains dissertations, research articles, educational and methodological materials, monographs, and regulatory documents. The collections cover a wide range of fields: from aerospace technologies, engine engineering, and computer science to history, linguistics, mathematics, and ecology. The archive brings together the scientific heritage of the university, including materials prepared during the period of Samara State Aerospace University and Samara State University.
Looking for publications by author, title, date, or subject? Full-text search will provide relevant results. Want to explore the academic life more closely? Browse materials by the universityâs organizational units.
Descriptions of all publications and articles available in the repository can be found in the libraryâs electronic catalog. Staff and students can log in via the menu "Login -> My Resource Archive" using their personal account credentials (SSAU_id).
Use the archive for study, research, and professional development!

| Abstract: | Theses are devoted the Thermionic Cooling System (TCS) of the turbine blades (TB) and other thermointense elements (ТЕ) of the gas turbine units (GTU) and engines (GTD) made of ceramic materials with metallic conductivity (borides and carbides). The essence of TCS consists in increase in thermoemissive capacity of surface of LT and ТЕ (ensuring electron work function ). So, during electron work function of surface of TB from borides ceramics in 2.7 eV reduction of temperature by 120-150°C and decrease in temperature stresses by 50-60% is possible. Thus, TCS allows to solve the main problems of TB and ТЕ from borides and carbides (low crack resistance) without the need for the difficult internal cooling system. |
