Abstract: The flying traj ectory simulation of the store after being separated from the mother plane is an advanced and difficult technique in wind tunnel test.In this paper,the continuous dy-namic traj ectory simulation technique is studied in the Captive Traj ectory System (CTS)used in a transonic wind tunnel.This paper initially introduces the dynamic trajectory predicting principle. Then,the specific steps of the coordinated control method of continuous dynamic trajectory simu-lation are amply described.The algorithm and constraint condition of the coordinated control and the buffering coordinated control are also discussed.Finally,the Taylor mean value theorem is applied to build a Kalman filtering model to resolve the conflict between filtering delay and accu-racy requirements.After choosing appropriate parameter,the Kalman filtering is used to process the balance signal dynamically and in real time,and the comparison between the continuous dy-namic control process and the move-and-stop control process is carried out.The wind tunnel CTS test result shows that the Kalman filtering can reduce the signal fluctuation greatly,meet the re-al-time requirements of CTS,and dynamic separation trajectory of the continuous dynamic con-trol process metches well with the one of the move-and-stop cortrol,while the wind tunnel CTS test efficiency has also been considerably improved.
