Application Practice of Launch Vehicle System Design Based on SysML

In order to meet the needs of launch vehicle development characterized by high quality and efficiency, the method of launch vehicle system design based on SysML (Systems Modeling Language) using MBSE (Model Based Systems Engineering) is proposed. Different from traditional MBSE methods, this method for modeling launch vehicle system has only a few processes and steps, which is simpler, clearer and easier for launch vehicle designers to understand and operate. Taking a launch vehicle as an example, this paper uses the method to design and validate system, which fully embodies the advantages of the method and verifies that it can well meet the design requirement of launch vehicle.
