ABSTRACT:
The system for mounting and attaching turbine and compressor prismatic rooted blades includes a mounting sector formed by the elimination of two circumferential flanges provided on the edges of the rim. The length of the sector is about three widths of the blade platform with a stop-blade having two diametrically opposite cut corners and a four-tooth stop-comb. The corresponding mounting procedure consists of turning the stop-blade between the vanes placed in the bottom of the sector and passing its platform above those of the two adjacent blades. The comb is introduced between the platforms of the three blades and the bottom of the sector.
