| 摘 要： | 现有文献中的翼伞建模方法多数是针对不带动力情况下的翼伞建模,不能适应动力翼伞的飞行控制。为了实现动力伞的有效控制,首先要建立合理的动力学模型。假设翼伞承载物和软翼之间具有2个自由度,分别建立软翼和承载物体坐标系下的作用力和力矩的平衡方程,通过体坐标系转换和消除翼伞内部状态量,得到有利于实现翼伞控制的8自由度非线性状态方程。仿真表明模型的飞行曲线与飞行实验的结果相一致,验证了模型的有效性。

| Abstract: | A number of methods for modeling a unpowered paraglider have been proposed so far,which are inapplicable to a powered paraglider.In order to get better control of powered paraglider,a available dynamic model must be built firstly.Under the assumption that the payload has 2-DOF,state equations of forces and moments under canopy and payload coordinate system were built respectively,and a 8-DOF nonlinear state equation of the powered paraglider was gained through transformation of coordinate systems and elimin... |
