In the bladed machine, according to the first embodiment, comprises a body with central and peripheral channels of passing of a working medium, which is jointed with an external machine by means of arbor, on which there is fixed one hub of axial working runner, having a circular system of blades, sequentially alternating lengthwise the axis of the arbor with a circular system of guide vanes of controlling apparatus, the vanes are fixed in the body, the working runner is furnished at least one ring-type bush, which is hard by bound with the hub of the working runner and a circular system of the working runner blades and the controlling apparatus of guide vanes, which are accomplished at least in two rows with the central row and the peripheral row with the circular systems of blades and guide blades correspondingly. The blade machine, according to the second embodiment, comprises a body with central and peripheral channels of passing of a working medium, which is jointed with an external machine by means of arbor, on which there is fixed one hub of axial working runner, having a circular system of blades, sequentially alternating lengthwise the axis of the arbor with a circular system of guide vanes of controlling apparatus, the vanes are fixed in the body, is provided with the second working runner with a hub, encompassed by the first working runner and kinematically connected to an additional shaft, connected to a shaft of an outer machine, the circular systems of the working runner blades and of controlling apparatuses of the guide vanes are accomplished in three rows with a peripheral and middle circular rows of the blades and guide vanes correspondingly. In each embodiment the working runner blades and guide apparatus vanes circular systems are made as biplanes - with the periodically alternating blades and vanes of an unequal length. |
