Ultra-efficient bladeless turbomachinery

A reversible turbomachine configured to operate in turbine mode transforming energy of a fluid into mechanical energy or configured to operate in compressor mode for transforming mechanical energy into energy of the fluid, said reversible turbomachine comprising:

• a rotor housing containing one or more members of a rotor, the rotor comprising a plurality of mutually spaced disks rotating about a rotation axis and coaxially arranged about a rotation shaft;
• a primary stage for a flow of the fluid having high energy, communicating with the rotor housing via a statoric channel;
• a secondary stage for the flow of the fluid in low energy state;
• and
• a rotating distribution chamber for distributing said fluid to or from the rotor, said rotating distribution chamber being arranged in an internal space of the rotor housing and interposed between the statoric channel and at least part of said disks, said rotating distribution chamber being provided with at least one rotor opening for the flow of the fluid between the primary stage and the rotor.
