Clamping device for clamping e.g. nose bullet of propeller of ducted-fan turbine engine of aircraft, has radial deployment unit making groove to extend from retracted position, which allows passage of flange, to deployed tightening position

摘要

The device (50) has an annular shaped tightening groove (56) receiving annular flanges (40, 42) of two parts of a turboshaft engine. The tightening groove is radially opened toward outside, and a radial deployment unit (62) makes the groove to extend from a retracted position, which allows passage of the flanges, to a deployed tightening position. A ring (54) includes two circumferential ends facing and spaced from each other and interconnected by radial extension. The unit includes a tensioning compass including branches whose free ends are mounted on circumferential ends of the ring.
