ABSTRACT:
The invention relates to a high peripheral speed centrifugal compressor of the kind comprising curved hollow sector shaped scoops juxtaposed circumferentially about an axis to form a disc, and a drive shaft for rotating said disc about said axis.
According to the invention, the scoops are made from material loaded with high mechanical strength fibers and are connected together circumferentially and radially by filaments wound and stretched in radial clearances between the scoops, the filaments being of material generally similar to the fibers of the scoops and being coated with a bonding agent compatible with the material of the scoops and the filaments, the bonding agent being cured so as to bond the scoops and filaments solidly together in the form of a stable unitary member.
The resulting wheel has light weight and high mechanical breakage strength, enabling high peripheral speed.
