Abstract
A new lightweight bladed rotor for gas turbine or turbojet engines combines an inner support ring with blade straps made of fiber reinforced material. The blade straps wrap halfway around the inner support ring so that their ends extend radially outwardly to form blade pairs. A rim connects the blade straps near their ends to provide rigidity and to define a flowpath.
