GAS TURBINE ENGINE BLADE Abstract of the Disclosure A gas turbine engine blade is disclosed which includes a dovetail having retention lobes and fillets. Compression means are provided in the dovetail for introducing compressive prestresses at the fillets for reducing tensile stresses at the fillets due to loads in the blade such as centrifugal tension loads. In an exemplary embodiment, the compression means comprises a cavity in the dovetail and an insert disposed therein in an interference fit for generating compressive stresses at the cavity and at the fillets.
