Abstract

Model-Based Systems Engineering (MBSE) is a part of a long-term trend toward model-centric approaches. The Authoritative Source of Truth (AST) is a crucial step of digital transformation and a core component of MBSE. Benefits include help design teams shorten the design cycle, improve design efficiency, and ensure the accuracy of design models and data compared to traditional document-based co-design methods. Data-driven design is a new direction of Unmanned Combat Aerial Vehicles (UCAV) design, and UCAV is the main force of future air warfare. How to build a UCAV conceptual design AST system is a problem that needs to be solved. We design an AST construction methodology, develop an AST system by applying the methodology, and use the UCAV concept design case to test the usability of the AST system. More specifically, the methodology includes construction goals and objects, basic construction methods, AST architecture, collaborative construction methods, dynamic management methods, basic functions and derivative tools required. In addition, the validation process is requirement analysis, functional architecture design, scheme design, and dynamic management validation. The AST system can help the implementation of MBSE in the field of aircraft design. The AST system can also help meet the requirements of the conceptual design stage, which shows the feasibility of the construction methodology’s integrity. If the AST system is used in the aircraft’s detailed design phase, further models and data will be required, and the AST system will need to be upgraded.

Highlights

A IRCRAFT design and spacecraft design are mainly based on system engineering [1], [2]
Model-Based Systems Engineering(MBSE) is the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases [3], [4].NASA has successfully applied the MBSE method in several projects [5]– [7], such as the Europa project
1) Improving the models and data reusability: The X2030 Unmanned Combat Aerial Vehicles (UCAV) co-design model is repeatedly applied during the design process, which reduces the time for a single design

Summary

INTRODUCTION

A IRCRAFT design and spacecraft design are mainly based on system engineering [1], [2]. C) View Editor(VE) enables users to interact with SysML models within a web-based environment It implements the MMS REST(Representational State Transfer) API(Application Programming Interface) to provide a web environment to create, read, and update model elements, including Documents and Views. We designe the AST construction methodology, which focuses on how models and data are collected, managed, and applied. An AST is a core and base to MBSE, which is closely related to the model and data in the conceptual design of UCAV. The novel contributions of the proposed framework are as follows: 1) Design an AST construction methodology, including construction goals and objects, basic methods of construction, the architecture of AST, collaborative construction methods, dynamic management methods, basic functions and derivative tools required.
