ABSTRACT:
A rotor for jet engines includes a drum formed by disks and carrying blad Between the blades of two adjacent stages, braces are interspaced, the braces being projections which engage in sockets provided for this purpose on the disks. Each disk has two series of sockets, one receiving the roots of the blades, and the other, interspaced between the preceding, the projections of the braces. The blades are immobilized in translation at the upstream end by one ring and downstream by another ring, against which the roots of the blades of the terminal stages abut. The invention is particularly applicable to the building of axial type compressor rotors having several stages.
