摘要： 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.

摘要翻译： 本发明考虑了对燃气轮机的内部部件的保护措施，由此进入涡轮机的入口气体的异物在入口管道的局部易碎区域即涡轮机暴露之前受到强烈的离心作用。 选择易碎区域的材料和结构使得大于预定质量的异物会破裂，从而避免在燃气轮机中摄取这些物体。 本发明描述了一种涡轮增压器的情况，该涡轮增压器由来自内燃机的排气操作，并向发动机供给压缩的入口空气; 在脆弱区域破裂时，为了安全地处理发动机排气而建立了转向旁路流向燃气轮机排气并用于及时发展合适的警告。
