Abstract

An axial flow turbine diaphragm (10) is constructed without welding or other metal fusion or melting techniques. Static blade units (16) are attached to inner and outer diaphragm rings by radially inner platform portions (162) that engage the radially inner ring (12), and radially outer platform portion s (163) that engage the radially outer ring (14), the inner platform portions being elongate in the circumferential direction of the turbine diaphragm and the outer platform portions being elongate in a direction compatible with the stagger angle of the aerofoils (161). The outer circumference of the radially inner ring (12) has a blade unit retaining feature (124) of complementary shape and orientation to the inner platform portions (162) of the static blade units, and the inner circumference of the radially outer ring (14) is provided with a plurality of blade unit retaining features (147) of complementary shape and orientation to corresponding outer platform portions (163) of the static blade units.
