Study on reliability simulation for flight control system under the influence of wind

Reliability is an important design index. Variable wind speed is one of the important factors causing trajectory scatter. For the large and complex system, it is too difficult to analyze the reliability using the analytic methods, but the computer simulation is an effective way. Reliability simulation for flight control system is studied in detail by considering variable wind speed. The model of wind is established and randomized. Influence principle of wind for flight control system is studied, and motion equations of missile are modified. Algorithm of reliability simulation is discussed in detail, and formulae of computing reliability are given. Finally, the method is verified by X-missile's flight control system.
