In recent decades,the design of complex systems like launch vehicles in the aerospace industry has presented engineers with challenges that go beyond system *** such as time-to-market pressures and intricate industrial processes have underscored the increasing significance of agile design *** design is derived from the simplification of the design process and enhancing cross-domain data transmission and *** methods based on model-based system engineering have improved iteration times in system architecture design,challenges persist in cross-domain data *** to the diversity of complex system models and data,a single-mode integration method is difficult to realize the data link construction of all tools *** address this challenge,this paper proposes a dualmode data integration framework with expansibility,universality,and cost-efficiency which leverages the benefits of Remote Procedure Call and Intermediate Exchange Module,addressing the challenge of constructing cross-domain data links under single-mode *** this study,two critical requirements of the first-and second-stage separation systems,namely,weight and minimum separation gap,are selected for data feedback.A modelica-based multiphysics simulation model is developed in MWorks;visualization and computation of the minimum gap are carried out in *** bridge the gap between domain-specific tools,Matlab and Functional Mock-up Unit modules are introduced as middleware,facilitating data feedback *** entire simulation process is orchestrated using activity diagrams in the MagicDraw *** study delves into the influence of critical design parameters,such as the initial angular velocity of separation and the thrust of the retro rocket,on the minimum separation *** provides an analysis of minimum separation gap variations under uncertain operating conditions and examines design ***,the paper highlights the signifi
