ABSTRACT:
A turbine engine rotor includes two bolted, coaxial sections. One of the sections carries blades engaged by their roots in through broachings. The axial force exerted on the blades by the centrifugal operating component due to the inclination of the broaching is not transmitted to the bolts joining the two sections as a result of a mounting where the flanges are joined at their rear faces. The blades abut against the flange of the other of the sections. The invention is more particularly applicable to highly curved, so-called large chord blades of a turbine engine fan and the other of the sections is then a low pressure compressor drum.
