摘要
文章用半经验充气时间法对用于某回收器降落伞系统的收口十字形降落伞的充气过程进行了动力学建模与仿真计算,通过参照第一次某回收器飞行试验遥测数据,调整经验参数的值,对动力学模型进行修正。用修正后的动力学模型对第二次回收器飞行试验进行了仿真计算,将仿真计算结果与第二次飞行试验遥测数据的开伞动载以及运动参数进行比较,比较结果具有较好的一致性,证明了动力学模型和仿真计算程序的正确性。
The dynamics models are built and simulated of a reefed cruciform parachute for certain new Unmanned Aerial Vehicles （UAV） parachute system with semi- empirical inflation time method. The dynamic models have been modified by changing the values of experimental parameters through being compared with the first flight telemetery data of UVA.By using the adjusted dynamics models,simulation calculation is made according to the second test working condition of UVA inflation process. The simulation results are well in comparison with the second flight telemetery data of UVA, so the dynamics model and simulation are validated.
