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
