Abstract: Sealing systems of turbo-machines determine possibilities of intensification of working processes in it. Facegas-dynamic seal are a standard technology solution for compressors. The aim of a present research is modernization of face gas-dynamic seal structures and research of processes in it. In the present studies ways of seal structure modernization are formulated. Results of experimental research of seal thermal condition are presented. It is found that in the seal a laminar gas flow is realized.
