摘要
首先建立了初始充气模型 ;将前体、伞绳及伞衣离散为一系列弹性连接的质量节点 ,伞衣内部流场为一维不可压流 ;最后利用模型计算了初始充气阶段伞衣形状变化。
An initial inflation model for parachutes is established. The forebody, suspension lines and canopy are modeled as a series of elastically connected mass nodes. The flow field inside canopy is one-dimensional incompressible flow. Finally, the model is used to calculate the variations of canopy shape, the variations of canopy projection area and the tension of suspension lines during initial inflation phase.
