ABSTRACT:
The rotor is supported within the duct by a stationary flow-straightener with vanes connecting the wall of the duct to a central body housing the mechanism for driving the rotor. This mechanism is surrounded by a casing equipped with radial arms bearing removable means for fastening to an internal flange of the body, so as to fasten the flow-straightener and the casing rigidly to one another, and both into the duct.
