This invention can be used in various fields.
RENEWABLE ENERGY.. Used in conjuction with a wind driven fan upstream, the air is accelerated through the various volume reduction stages and is used to increase rotational speed of the shaft connected to the generator.
AUTOMOTIVE - air intake compressor and/or turbo charger for fossil fuel engines. Air driven generator to charge batteries on EVs while on the move.
AVIATION - Use as the compressor stage in a Gas Turbine Engine (JET), Use as an engine itself, just adding a combustion chamber
to drive a turbine.
Industrial compressors.
A True game changer.
This invention relates to a multi-stage rotor (10). More specifically, the invention relates to a multistage rotor (10) for the compressor stage of a machine that, through a concentric configuration of its innermost (12), outermost (24) and intermediary (16) blade sets co-operative with a reverse flow convoluting ducting arrangement, provides an axially compact, lighter and more easily maintainable compressor rotor for such machine. The multi-stage rotor (10) includes innermost (30), outermost (34) and intermediary (32) duct ports comprising a radial duct spans, as measured between respective diametrically inner and outer duct walls of the duct port, being greater than respective innermost (48), outermost (54) and intermediary (50, 52) radial blade spans of the respective blade sets rotatable at least partially within such duct port. In this manner, a gap is defined between: (i) the at least one diametrical ends of the radial rotating blades ending radially short of the respective radial duct span to form free ends of the blades; and (ii) a stationary part of the respective duct the free ends of the blades sweep neared to; for generating a friction wash between such free ends of the blades and the stationary part of the respective duct.
