Abstract:
An assembly includes a one-piece bladed disk, at least one low-pressure compressor rotor, and a low-pressure compressor shaft. The bladed disk and the low-pressure compressor rotor are both adapted to be shrunk onto the low-pressure compressor shaft and mechanically attached to it by sets of splines. At least one clamping member blocks axially the different collars with respect to the shaft.
