ABSTRACT:
A method of manufacturing an axial flow compressor stator assembly in which a plurality of aerofoil cross-section stator vanes having divergent inner and outer extents are encapsulated in a low melting point alloy so that their extents protrude from the alloy. The vanes are encapsulated in the same relationship with respect to each other which they would assume in a compressor. A moulding material is then moulded around the radially inner and outer extents to define arcuate bridging member which interconnect adjacent stator vanes. A stiffening member is bonded to the bridging piece interconnecting adjacent radially outer stator vane extents and the whole assembly heated to melt the encapsulation alloy.
