Abstract

A rotor for centrifugal compressors and fans, of the type comprising a ring of blades (1) connected to a central hub (6) with an annular flange (7), is formed simply and economically by providing the root of each blade (1) with an integral appendage (2) which lies in a plane perpendicular to the axis of rotation and fixing the appendage (2) of each blade (1) to both the appendage of one of the blades adjacent thereto and to the flange (7) of the hub (6). Each blade (1) and its appendage (2) are conveniently made by pressing from sheet metal and the form of the appendages (2) is such that together they constitute a disc for a rotor of the semi-closed type or one of the discs for a rotor of the closed type.
