The invention is directed to a turbo-engine, particularly internal combustion engine, comprising a housing and therein a bladeless turbine section (30; 42; 67) of the stacked disc- or Tesla-type construction, wherein the turbine section (30; 42; 67) has a plurality of closely spaced discs (32; 49; 61) arranged for common rotation about a rotation axis in the housing, said turbine section (30; 42; 67) is adapted for passing with tangential flow components a working fluid stream from a radially inner region to a radially outer region of said turbine section (30; 42; 67) while adopting energy from said working fluid stream for rotating the discs (30; 49; 61). Preferably, the turbo-engine further comprises a compressor section (40; 66) of the stacked disc- or Tesla-type construction having a plurality of closely spaced discs (45; 61) arranged for common rotation about said rotation axis and a combustion zone (41; 64), wherein said compressor section (40; 66) being arranged coaxially with—and radially inwardly of the turbine section (30; 42; 67) with the combustion zone (41; 64) provided radially between the compressor section and the turbine section.

A gas compressor comprising a drum affixed to a rotating shaft, the drum including a plurality of compression channels between a common pressure zone and an interior surface of the drum distal to an axis of rotation. A static vane return assembly adjacent the compression channels includes vanes extending from an inlet at an outer circumference to the common pressure zone and directing gas into the common pressure zone, either through the vanes or via separate channels or ducts. Fluid inside the rotating dmm forms an annular lake that is drawn through the vanes and into the common pressure zone. Fluid is then forced into the compression channels where gas in the fluid is compressed as it travels from the common pressure zone toward the interior surface. The pressurized gas is separated from the liquid prior to leaving the compression channel assembly while the liquid is returned to the lake.

A boundary layer turbomachine can include a housing defining an interior space and having an inlet opening and an outlet opening to facilitate movement of a fluid through the housing. The boundary layer turbomachine can also include a rotor assembly disposed in the rotor chamber and configured to rotate about an axis of rotation. The rotor assembly can have a plurality of disks spaced apart along the axis of rotation and defining an interior opening along the axis of rotation. The fluid can pass through gaps between the disks and the interior opening as the fluid moves through the housing.

A fan impeller includes a hub, a plurality of annular blades, and a plurality of spacers. The annular blades are stacked along an axial direction of the hub and disposed around the outer periphery of the hub. The extension directions of the annular blades are perpendicular to the axial direction of the hub. Each of the spacers is disposed between the two adjacent annular blades. Each of the annular blades has an inner periphery. A gap is provided between the inner periphery and the hub. Each of the annular blades further includes a plurality of spokes and an inner ring, the inner ring is disposed on and connected to the outer periphery of the hub, and two ends of the spoke are connected to the inner periphery and the inner ring of the annular blade. The spacers are separately disposed on the inner rings of the annular blades, respectively.

A tray-type fan impeller structure includes a plate body annularly disposed around a hub. The plate body has a connection side connected with the hub and a free side extending in a direction away from the hub. Multiple boss bodies are arranged on a top face or the top face and a bottom face of the plate body at intervals. By means of the boss bodies, the periodical noise problem caused by the conventional blades is improved.

The present invention relates to a disc turbine for converting the energy associated with a fluid into mechanical energy. The turbine (1) comprises a housing and a rotor (4) inside said housing (3) which can rotate with respect to it about a rotation axis (100). The rotor (4) comprises a plurality of disc elements (11A, 11B) coaxial with said axis. The turbine is characterized in that it comprises a distributor (5) with a distribution wall (5A) which at least partially surrounds the discs. Such a wall (5A) is arranged inside said housing (3) so as to define a diffusion chamber (7) with the housing itself, which chamber at least partially surrounds the distribution wall (5A). The latter comprises a plurality of nozzles (6A, 6B, 6C, 66A, 66B, 66C), each of which is provided with an inlet section (61) communicating with said chamber (7), an outlet section (62) adjacent to the discs (11A, 11B), and a converging portion (615) which accelerates said fluid towards said outlet section (62).
