Application of experiment design method in performance simulation validation for flight vehicle

Through data sampling and statistical analysis of results,design of experiment(DOE) method provides an effective way for flight performance analysis of flight vehicle under a variety of errors and disturbances.This paper gives an introduction of the DOE methods,and presents the approach of integrating DOE methods and simulation methods.The approach makes an easy way to implement the application of DOE in flight simulation.The sample result shows that these methods could not only reduce the cost of their calculation,and but also achieve flight envelope,and implement the assessment of flight performance.
