基于过载与姿态参数的开伞载荷快速分析方法

Rapid Analysis Method of Parachute Opening Load Base on Acceleration and Attitude Parameters

结合近期国内首次成功实现的助推子级伞降回收任务,基于实测过载和姿态参数,提出了回收过程中稳定伞、减速伞和翼伞开伞载荷快速分析方法,分析结果与设计载荷吻合较好,充分验证了开伞载荷快速分析方法的有效性及设计载荷的正确性,可供后续伞降回收任务载荷分析参考。

Combined with the first successful recovery task of booster in China recently,based on the measured acceleration and attitude parameters, a rapid analysis method for parachute opening load of stabilizing, decelerating and parafoil during recovery is proposed. The analysis results are in good agreement with the design load, which fully verifies the effectiveness of the rapid analysis method and the correctness of the design load. It can be used as a reference for load analysis of subsequent parachute recovery tasks.
