The quality management of aerospace product is related to multilevel suppliers and runs through its whole lifecycle. Considering the complexity of aerospace product, the quality management mode of aerospace product developing process is proposed. Three models including Product Quality Information Tree (PQIT), Product Quality Information Model of Lifecycle (PQIML) and Feature Model of Quality Problem (FMQP) are proposed to describe the all-sided quality information of the product in each period of the developing process. On the basis of these models, the systematic quality control method including the method of product quality prediction, process quality management, quality problem tracing and quality analysis and decision-making is presented to manage and control the aerospace product. At last, the application of this method is discussed in real quality management of rate gyroscope to demonstrate the efficiency of this method. The result showed the quality information of rate gyroscope in the whole lifecycle can be restored and utilized effectively using the method proposed.
