1. turbogenerator that is used for aircraft (1) with longitudinal axis (L-L) comprising:

  • -suction port (2), it has tubular inner wall;

    With-blower (3), it surrounds by described suction port supply air and by the case (11) of same tubulose,The front end of the rear end of the described inwall of this suction port and the described case of this blower has the flange connector of the periphery protrusion of cooperation respectively, and link together as screw, bolt or analog by first fastening piece (16) that passes described flange, and the axis of described first fastening piece (1-1) is parallel to the described longitudinal axis (L-L) of this turbogenerator at least approxIt is characterized in that;

    The described inwall (23) of-this suction port (2), it comprises the flange connector (24) of described rear end (2R), the parts of being made by the fiber/resin composite material (22) form;

    -at the opposite side of the front end (11A) of described case (11), the channel portion (24) of the projection of described rear end (2R) is connected on the described inwall (23) by the circular contour (25) that is recessed toroidal at least approx;

    -stiffening ring (26) is connected on the described rear end (2R), described stiffening ring is fitted with the described circular contour (25) that is recessed toroidal at least approx, and be connected on the described rear end (2R) by second fastening piece (27), the axis of second fastening piece (x-x) is orthogonal to the longitudinal axis (L-L) of described turbogenerator at least approx;

    And-described stiffening ring (26) passes and is compressed against on the described flange (15,24) of cooperation by described first fastening piece (16).
