Evaluation methods of missile flight reliability based on multi-source information fusion

Aiming at the problem that the data of the whole system flight test is limited, the environmental factors and reduced algorithm have been introduced into the evaluations of the missile flight reliability in this paper, and the equivalent conversion method of multi-source reliability test data has been investigated. Primarily, the component test data has been converted into the whole missile data by applying equivalent conversion method; then, the ground test data has been converted into flight test data by applying Weibull distribution environmental factors; finally, the missile flight reliability has been evaluated by applying the converted data. The numerical examples have also been given to verify the validity and feasibility of the method, which effectively expand the number of evaluation samples, and improve the overall quality and efficiency of the test.
