Abstract
The invention relates to a blade-free type turbine, and belongs to the technical field of thermal power installations. The blade-free type turbine comprises an internal sleeve, an external sleeve, a rotor spindle, a sealing ring and an air inlet nozzle. The turbine can be used as an acting part of minitype and ultra-minitype combustion gas turbines. A boundary layer principle is used to enable an airflow entering the turbine to drive the internal sleeve and the rotor spindle to rotate, and act outward, and thus the limitation of a blade in the traditional turbine is got rid of. The defects that the requirements of a Tesla turbine on material strength of a disc blade are overhigh and the disc blade is poor in deformation stability in a running process are overcome, meanwhile, the problems that the blade structure of the traditional combustion gas turbine is complex, the manufacturing request is high and the maintenance is difficult are solved, and the novel blade-free type turbine adopting the boundary layer principle is provided.
