Engine Validation and Reliability

An integral part of the engine design process is that of ensuring that the product has sufficient reliability and durability. As used in this book durability refers to the useful life of the engine. For the engine system this is the average life-to-overhaul. For most of the major engine components it includes an expectation of reuse when the engine is overhauled. Reliability includes also infant mortality and the unforeseen problems that require attention over the engine’s operational life. Engine design and development must include validation processes to ensure that the durability and reliability expectations are met. The success of this endeavor is crucial to the success of any engine design.
