ABSTRACT
Compliance with stringent military airworthiness standards is essential for the certification of combustors for use in aero gas turbines and this chapter describes the method of integrating the physical tests and finite element simulation in order to ensure safe operation of the combustor throughout its intended life. The chapter focuses on the evaluation of the fatigue life of an annular combustor used in an afterburning turbofan engine producing 80 kN thrust. Metal spinning is the process of forming three-dimensional symmetrical parts from flat circles of metal. Metal spinning provides an economical alternative to stamping, casting, and many other metal-forming processes. Electron Beam Welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. It is regular practice that a nondestructive technique is followed to carry out inspection of critical aero engine components at various stages of testing.
