FIELD: mechanical engineering.
SUBSTANCE: invention relates to heat and power engineering and mechanical engineering and can be used in the capacity of pumps, compressors, power plants with outer and inner heat supply for stationary and mobile objects. Turbine contains two axial cylinders, between which it is installed rotor faceplate and relative to each it is implemented, at least, by one co-axial cylinder, blades. Cylinders, which are in the same diametral plane, are concatenated to each other by means of passageways, communicating to cylinders' cavity in area of intervane capacities decreasing from maximal up to minimal in one and simultaneous increasing from minimal up to maximal in other forming, at least, one spiral air-gas channel of compression or expansion. Passageways of air-gas channels are circumferentially separated from each other by areas, including its communicating to each other of length not less than blade spacing. Induction and exhaust ports are implemented in the first and in the last cavities of air-gas channel.
EFFECT: turbine provides at its application in different heat engines of external and internal combustion to provide transformation of all potential energy of operating heat directly into mechanical and correspondingly provide indexes of high efficiency, affordability, ecological purity, and also overall-weight behaviour and minimal specific weight.
