FAN DISK OF TURBOJET ENGINE AND TURBOJET ENGINE Russian patent published in 2021 - IPC F01D5/14 F04D29/32 

FIELD: turbojet engines.

SUBSTANCE: invention relates to a fan disk of a turbojet engine, through which a gas stream flows in one flow direction. The disk has a radial section in the form of a pin, containing the first branch made with the possibility of attachment on a drive shaft of the turbojet engine and containing an inner shell, and the second branch located opposite to the first branch and made with the possibility of installation of a set of fan blades on it, and a curve connecting wall located between the first branch and the second branch. The radial section of the connecting wall is essentially straight between the inner shell and an intermediate zone of the connecting part, adjacent to the second branch, and then it becomes a curve in the zone adjacent to the second branch, while concavity of the curve zone faces an output in the direction of gas flow.

EFFECT: invention is aimed at an increase in the reliability of turbojet engines.
