A turboprop including a propeller shaft and a gas generator running along this propeller shaft, this gas generator including a high-pressure shaft and a hollow low-pressure shaft both extending along the same longitudinal axis, the low-pressure shaft having a rear end coupled to a rear end of the propeller shaft via a reducer. It includes an accessory box contiguous to the reducer while being located facing a rear end of the low-pressure shaft, and coupled to the rear end of the high-pressure shaft by a shaft passing through the low-pressure shaft.

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.
