摘要:

为提高运载火箭上升段逃逸救生策略的覆盖性和有效性,采用基于模型的系统工程(model-based system engineering, MBSE)方法开展设计。首先, 进行运载火箭逃逸救生任务分析, 识别相关系统及其任务需求, 建立任务需求模型。然后, 根据运载火箭飞行程序, 建立不同时刻的主要故障模型, 研究提出不同故障的可能应对策略, 形成功能需求模型。最后, 在逻辑仿真中调用弹道仿真程序, 验证了逃逸救生策略的可行性, 实现了需求的闭环验证。通过采用该方法, 完成了运载火箭上升段逃逸救生任务需求模型化, 奠定了全任务周期数字化设计的基础, 可为工程实践提供参考。

Abstract:

In order to improve the coverage and effectiveness of the escape and rescue strategy of launch vehicle ascending section, the model-based system engineering(MBSE) method is used in the scheme design. Firstly, the mission analysis of escape and rescue for the new launch vehicle is carried out to identify the related systems and their mission requirements, and then the requirement model is established. Then, according to the launch vehicle flight procedures, the main fault models at different time are established, and the possible coping strategies for different faults are studied and proposed to form the functional requirements model.Finally, the trajectory simulation program is called in the logic simulation to verify the feasibility of escape and rescue strategies, and then the closed-loop verification of the requirements is realized. By adopting this method, the requirement modeling of the escape and rescue mission of launch vehicles ascending section is completed, and the foundation of digital design of full mission cycle is laid, which can provide reference for engineering practice.

Key words: launch vehicle, manned spacecraft, escape and rescue, model-based system engineering (MBSE) method
