CENTRIPETAL TURBINE Russian patent published in 2019 - IPC F01D1/08 F01D5/14 F01D5/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to power, transport and aircraft engine building and can be used in technical facilities, where as energy source it is expedient to use high-temperature high-speed centripetal turbine with low volume flow of working medium, including turbo-compressors for pressurization of internal combustion engines and micro-power engineering. Centripetal turbine comprises a guiding device, a bod case y and a radial-axial impeller with a blading apparatus. At that ledge is made on outlet part of every blade of blades, while annular ledge is made on inner surface of the case opposite ledges at outlet parts of working blades. Value of gap between periphery of vane apparatus and case is constant.

EFFECT: improving turbine efficiency by 2–3 %.
