  • Patent number: 10921211
    Abstract: The invention relates to a device for simulating the centrifugal acceleration applied to at least one aeronautical turbomachine rotor blade. This device is notable in that it comprises at least one rotor disc (2) comprising a rim in which there are formed a plurality of pockets (23) delimited by two lateral teeth (24) and at least one simulation test (3) which comprises a screw (32), a spacer (33) and a dummy blade (31), in the dummy blade comprises a bore (347), which is tapped over at least part of its length and in that the dummy blade, the screw and the spacer are configured and arranged in such a way that when the screw is screwed into the tapped bore, the root (35) of the dummy blade is engaged in the pocket in the disc, the screw comes into abutment against the spacer and presses same against the two lateral teeth situated one on each side of the pocket in the rotor disc and that this causes the dummy blade to move towards the outside of the disc.
