Design and Structures of Aircraft Engines

Abstract

Structural integrity and optimal weight configuration of aerospace structures continue to be a challenging task. In the case of aircraft engines, the task poses further complexities relating to rotating components, thermal environment and fatigue considerations. This chapter outlines the engine operating environment, structural design practices, failure modes and some aspects of reliability as applicable to military aircraft engines. A few important structural design methodologies are discussed in detail including the testing and validation aspects. The current design trends and technical challenges involved are also addressed.
