中文摘要：

目前对翼伞系统工作在非正常条件下的运动特性缺乏理论探索,研究了翼伞系统双侧差量控制条件下的运动姿态变化规律.建立了翼伞系统6自由度动力学模型;选取相应伞型,借助MATLAB仿真软件,对翼伞系统工作在双侧等量控制条件下的姿态信息进行了分析;进一步对翼伞系统异常工作条件下的转弯速率、转弯半径、姿态角的变化特征进行了研究.结果表明,翼伞系统工作在差量控制条件下的转弯速率、姿态信息等有别于正常工作条件下的变化趋势.研究结论为翼伞系统的顺利应用,提供了更接近与实际工作环境的理论支撑.

英文摘要：

The change rules of the motion attitude of parafoil systems under asymmetric control on both sides were studied. A 6 degrees of freedom（DOF） dynamic model of the parafoil system was established, and the corresponding parafoil was selected. With the help of MATLAB simulation software, the parafoil system’s attitude information under asymmetric control on both sides were analyzed. Furthermore,the variation characteristics of turn rate, turn radius and attitude angle of the parafoil system under the abnormal work condition were studied. The simulation results show that the changing trend of its turn rate and attitude information are different from that under the normal work condition. The research conclusions of which can provide theoretical supports for practical working environment applications of parafoil systems.
