The invention contemplates a protective measure for internal parts of a gas turbine, whereby foreign objects in the flow of inlet gas to the turbine are subjected to strong centrifugal action at a locally frangible region of the inlet duct, i.e., prior to turbine exposure. The material and structure of the frangible region are selected such that foreign objects of greater than predetermined mass will rupture the same and thus avoid ingestion of such objects in the gas turbine. The invention is described for the case of a turbocharger which is operated by exhaust gas from an internal-combustion engine, and which supplies compressed inlet air to the engine; upon rupture of the frangible region, a rotor-bypassing flow is established to the gas-turbine exhaust for safe handling of engine exhaust and for use in prompt development of a suitable warning.
