Abstract：Recently the structure becomes more and more complicated, and the performance requirement becomes higher. More researches focus on the prognostic, health management, diagnosis and maintenance support. With the rapid development of computer network technology, the information construction continues to develop. The artificial maintenance and management cannot meet the requirement. So, it is necessary to design and develop the software system of aircraft structure prognostic and health management. In this paper, the aircraft structure prognostic and health management software system are designed and implemented. Firstly, the prognostic module is developed based on the physical model and database, in which the correctness is verified by lots of experiments and simulations. Furthermore, the health management and maintenance decision making are based on operation flow. In addition, several security mechanisms are developed to ensure the integrity and security of information, such as the unified identity authentication mechanism, digital signature technology and Secure Sockets Layer protocol. The system is developed based on B/S mode, and the testing result of the whole system is illustrated. The prognostic and health management program can be provided by this system. The system developed in this paper can support the decision making, save the manpower and resources, cut costs and meet the requirements.
