Abstract

846,623. Mounting compressor stator blades. WARNKEN, E. P. June 30, 1958, No. 20845/58. Class 110 (3). A stator casing and blade assembly for an axial flow compressor comprises a plurality of stator blades each having an aerofoil portion and a wedge-shaped root portion the casing or arcuate member secured therein having a plurality of wedge-shaped slots for engagement by the root portions and means for securing the root portion of each blade, to the casing or arcuate member. In Fig. 2 the inner wall of the stator casing 10 which may be of metal or resin-impregnated fibre glass is provided with a plurality of spaced annular grooves 14. Each groove 14 receives arcuate segments 17 provided with a plurality of blades 18. The wedge-shaped root end portion 21 of each blade is inserted in a wedge-shaped aperture 22 in the segment 17, and retained in position by the base of the groove 14 in which the segments are held by means of bolts 26. In another embodiment (not shown), the casing itself has a plurality of wedgeshaped slots which receives the root ends of the blades, the roots being held in position by a two-part strap member which encircles the casing and root end portions of the blades. The strap is correctly aligned by lugs on the outside of the casing.
