Thrust misalignment is one of the factors of effecting closeness of rocket
the six component test set can measure thrust misalignment. The basic principle of six component test set and the general step of modeling with time series analysis method is presented and data processing and modeling is carried out to understand the set’s dynamic character in this paper. Result of modeling is ARMA(2
1)
it accord with the result of theoretical analysis. Frequency and damping ratio can be gotten by analyzing model
it will provide some help to improve the configuration of the six component test set.
