| Abstract | Since 1990, by the order of the Joint-Stock Company “GAZPROM” the Research-Engineering Center “Ceramic Heat Engines” has been involved in the development of the stationary ceramic gas-turbine engine (CGTE) of 2.5 MW, efficiency 42% which is notably in excess of the characteristics of the serial-production engines of the similar power. Alongside the application of the ceramic materials, a goal to increase the fire and explosion safety of CGTE through use of journal and thrust oil beatings was set up. The refinement of the embodied design of the CGTE gas-static bearings was carried out on specially designed test beds, initially on simplified and then on baseline test beds. On all stages, the rotors were “rigid”, the balancing accuracy ensured the residual imbalance not exceeding 5–7 g*mm, the air cleaning provided the moisture separation of at least 90% with the filtration being not worse than 80μm. The tests were carried out by two stages: initially the journal beatings without the axial load applied and then the thrust bearing component with variation of the axial load within the 0.2 ≤ Presi/Pbase ≤ 1.2 were developed. The maximum speed was 30,000 rpm (noper = 23,000–24,000 rpm). Thus, the performed complex of the computation-experimental operations allowed the development of the gas-static thrust-journal beatings for the 250 N mass CGTE rotor. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
