IMPROVED DEVICE FOR ATTACHING BLADES IN A CONTRA-ROTATING TURBINE

The invention relates to a contra-rotating turbine (C) of a turbine engine (10) extending about an axis (X) and comprising an inner rotor configured to rotate about the axis of rotation (X), and comprising an inner drum to which an inner moving blading (22) is attached, an outer rotor configured to rotate about the axis of rotation (X) in a direction opposite to the inner rotor, and comprising an outer drum (50) to which an outer moving blading (20) is attached, the outer moving blading (20) comprising at least one attachment rod (212) extending through an opening (51) of the outer drum (50), the outer moving blading (20) being attached to the outer drum (50) via a clamping means (100) attached to the attachment rod (212) from an outer face of the outer drum (50), a set ring (80) being disposed around the attachment rod (212) in the opening (51) of the outer drum (50). 本发明涉及一种涡轮发动机(10)的反向旋转涡轮(C)，其围绕轴线(X)延伸并且包括：内转子，其被配置为围绕旋转轴线(X)旋转，并且包括内转鼓，在所述内转鼓上固定有内活动叶片装置(22)；外转子，其被配置为围绕旋转轴线(X)以与所述内转子相反的方向旋转，并且包括外转鼓(50)，在所述外
