FIELD: gas-turbine engineering; superlow power gas-turbine engines. SUBSTANCE: use of tunnel nanoturbocompressor in gas-turbine engineering, owing to use of constructional ceramics, makes it possible to solve the problem of creating effective gas-turbine engines of superlow power output. Such gas-turbine engines can be used in space vehicles, power plants with electrochemical fuel elements and in other power-generating systems, for instance, in steam-gas plants, and in road vehicles as engines. To increase efficiency of nanoturbomachines special tunnel channel are proposed for use in flow passage parts. Gas in said tunnel channels flows at high Reynolds numbers and, consequently, at low hydraulic resistance. Cylindrical rotor of turbocompressor is made shaftless, with gas static support and thrust being arranged on periphery of rotor to increase vibration reliability of turbocompressor. EFFECT: enlarged operating capabilities. 3 cl, 1 dwg |
