摘要
射流元件是某些飞行器姿态控制系统的关键部件,其切换性能是影响姿态控制精度的重要因素。在对射流元件切换过程进行分析的基础上,建立了射流元件非线性微分方程组形式的动态数学模型。通过对射流元件切换过程中活塞运动情况进行仿真、分析,找出影响切换特性的因素。对射流元件切换过程进行实验研究,实验数据与仿真结果吻合,表明所采用分析方法和所建立模型的正确性,为全面分析射流元件的性能和改进射流元件的结构提供依据。
Jet elements are the key element of the attitude control system of some aircrafts. The switch characteristics of jet element is critical factor to control precision. The analysis of the characteristics of the switch process of the jet elements is presented, and the math model of jet elements was constituted in the form of nonlinear differential equations. The characteristics of the jet elements are obtained through the simulation of the displacement of piston. The factors which affect the characteristics are studied. The experimental study of jet elements is presented finally. Both simulation and experimental result illustrate the correctness of the method and model. Those help to understand the performance of the jet elements and design the better jet elements structure.
