Abstract:Considering the status of the reliability and life management for internal aero engine, the fact is indicated that key component life wasting, cycle cost increasing, maintain efficiency declining are induced to a certainty. It is also pointed out that the core of life control and management is to command and supervise aero engine’s application course on the view point of full life cycle, to insure aero engine be used safely and economically with practical and feasible methods, to execute contract with standardization procedure so that contractor related to aero engine and accessories, ground maintain and sustain can cooperate with consumer orderly and effectively in the process of design, develop, technical authority, production and overhaul, and then achieve optimization in the greatest extent or degree among reliability, safe, cost and performance. The basic factors, programs and methods about life control and management for modular construction aero engine were expatiated, by drawing lessons from the experience of the developed countries and the research result of life control and management for some aero engine. Particularly the core problem of life control and management, such as the key component safe life, modular unit overhaul life and minimum issue life, is emphasized and analyzed.
