火箭助推器翼伞回收动力学仿真分析

Dynamical Simulation Analysis for Booster Recovery with Parafoil System

以基于可控翼伞回收技术的火箭助推器-控制平台-翼伞多体飞行系统为研究对象,采用拉格朗日乘子法建立了两体8自由度和三体10自由度多体动力学仿真模型,考虑了翼伞的表观质量特性和火箭助推器的气动力影响。研究了不同吊挂方式和有效载荷外形气动力对系统滑翔和转弯性能的影响。研究成果可以为翼伞系统的工程设计与应用提供参考。

Objected to a multibody dynamic system of booster-controller-parafoil based on parafiol recovery technology,a two-body simulation model of 8-degree-of-freedom and a similar three-body one of 10-degreeof-freedom were established with Lagrange multiplier method,apparent mass of parafoil and aerodynamic of booster considered. The effects on the performance of gliding and turning of suspension and aerodynamic of booster were studied and the results could be referred to parafoil system engineering.
