【摘要】 针对导弹性能评估的需要,文中建立了导弹六自由度模型,提出了基于六自由度模型的导弹气动力参数辨识方法,并采用该方法进行了某型导弹21个气动力参数的辨识,辨识数据与理论计算数据拟合较好、且在准确度允许的范围内,并利用辨识结果初步对导弹质量进行了评估。文中提出的方法对各种飞行器的定型试验具有一定的参考价值。更多还原

【Abstract】 For the demand of evaluating missile’s capability,this paper built missile′s six-freedom-degree model,and proposed the method of parameter identification based on the six-freedom-degree model,which was used to identify 21 aerodynamic parameters of a missile.The data identified was closed to the theoretical data,and in the range of certain error,and was used to evaluate the missile quality at the last.The method of introduced by this paper may be useful for finalizing the design of aircrafts.更多还原
