| description | The invention discloses a high-precision calculation method for complete parachute opening motion characteristics of an object-parachute combination, and belongs to the technical field of aerospace pneumatic deceleration. According to the method, partial simplification hypothesis introduced by a conventional object-umbrella combination dynamic model is reduced, the earth model and the atmospheric environment model are introduced to correct the calculation process of the conventional object-umbrella dynamic model, and meanwhile, models with different degrees of freedom are adopted for solving according to result requirements of different stages; therefore, the trajectory characteristics of the object-parachute combination in the whole stage of free flight, straightening inflation and stable landing are obtained.
一种物-伞组合体完整开伞运动特性的高精度计算方法，属于航空航天气动减速技术领域。本发明减少以往物-伞组合体动力学模型引入的部分简化假设，引入地球模型、大气环境模型对传统的物-伞动力学模型计算过程进行修正，同时根据不同阶段的结果需求采用不同自由度的模型进行求解，从而获得物-伞组合体自由飞行、拉直充气直至稳降着陆全阶段的轨迹特性。 |
