Material used shall be compatible with the operating life requirement, and the reliability and maintainability requirements. the construction of the gas turbine engine, except those
33、metals which are in constant contact with lubricating oil, shall be of a corrosion-resistant type or shall be treated to resist corrosion. In order to prevent deterioration due to corrosion, all bolts, nuts, studs, pins, springs, screws, fastenings, fittings, and fuel system component parts (interna
34、l and external) shall be of a corrosion- resisting material, or of a material treated in a manner that will prevent deterioration and render it resistant to corrosion. operating and shock stresses shall have an elongation of not less than 3 percent. Materials used in turbine and compressor rotating

The reliability prediction for the genera- tor set shall be based on the failure rate of parts and the
44、information specified in 3.3.3.1 . The design and application of these parts shall be such that the inherent mean-time-between-failure (MTBF) is not less than 3000 hours for class A and 1,000 hours for class B generator sets. the design prediction procedure of MIL-STD-756 and using the failure rate
