FIELD: engines and pumps.
SUBSTANCE: turbojet engine fan rotor has a single shaft (12) and at least two discs (10a, 10b), installed on the shaft to provide similar set of movable blades (2) when rotating about rotation axis of said shaft. At least the first disc (10a) installed on the moveable shaft can be rotated about rotation axis to form angular displacement of the second disc (10b) tangential plane. At least one of the two discs is designed to receive at least one means for connecting each blade (11). The connection between said disc and said means enables rotation of said means. Said connection is a hinged connection tangentially and axially movable.
EFFECT: it is possible to vary the pitch angle of fan blades of the turbofan engine, and the fan is simpler and smaller.
