Hermetics mechanics is a unique discipline, introduced only in the Sumy State University.

Seals play a decisive role in ensuring reliability, efficiency and environmental safety of technical equipment in all industries from pumping sewage to ending nuclear power and space technology. Seals destruction is often major cause of man-made disasters.

Hermetics mechanics as academic discipline only one in the higher education system in the world. It has been achieved through a multi labor department, which formed the basis of discipline not only as a new scientific direction, but the modern academic discipline that synthesizes the latest achievements of many fundamental and applied sciences.

Problems of sealing sre very relevant and interesting for researchers. For example, in rotor machines (pumps, compressors, turbines etc.) in places of the end of rotor is inevitable gaps through which flows a working environment that is inside the machine under pressure to 50 MPa. This leakage leads to unacceptable loss of fluid and pollution. Therefore, seals are the most important units of machines, because preventing unproductive and harmful loss of raw materials and finished products.

Aircraft and rocket will not fly, the car will not go, the ship will not sail without reliable sealing devices.
