摘要：
A rotor having a bladed disc and for use in a fluid flow machine has plates extending between and supported by the blades to protect the disc rim from erosion and foreign object damage and also, when the rotor is a gas turbine, to protect the disc rim from the heating effects of high temperature gasses. The plates are held between ridges on the blade faces.
