Objective To study and track the reliability growth of manned spaceflight cabin borne equipment in the course of its development. Method A new technique of reliability growth estimation and prediction, which is composed of the Crow model and test data conversion (TDC) method was used. Result The estimation and prediction value of the reliability growth conformed to its expectations. Conclusion The method could dynamically estimate and predict the reliability of the equipment by making full use of various test information in the course of its development. It offered not only a possibility of tracking the equipment reliability growth, but also the reference for quality control in manned spaceflight cabin borne equipment design and development process.
