Integrated Design and Verification Method of Aircraft and Propulsion System

Abstract

Aircraft design engineering is multi-disciplinary, which includes the flight control system, the aerodynamics and the propulsion system. Their design and verification need an interdepartmental coordination. Traditionally, the requirement analysis, the system design and simulation are processed independently. It is difficult to establish a standardized communication mechanism for engineers from different departments. Thus, there was a challenge to achieve the co-design of aircraft subsystem based on the standardized system architecture. This paper presents an integrated design and verification method of aircraft and propulsion system. The idea is to convert the system-level model to a standardized system architecture which contains structure and constraint. The system-level model based on Systems Modeling Language (SysML) can be exported to Extensible Markup Language (XML) which can rebuild the system architecture using Meta model. In this way, the system architecture becomes a guide for aircraft model-based design and verification.
