A Design Based on SysML for High Lift System of Civil Aircraft

Abstract

With evolution of advanced technologies and new design concepts, new functions and complex interactions are introduced into High Lift System (HLS), which cause requirements to be captured difficultly and system architecture unable to be determined through traditional documents/text to capture requirements and present system architecture, especially iterative revise on requirements and scheme will lead to system design confusion. An effective method of MBSE based on SysML has been required and applied in design of engineering field, such as an aircraft of China. This paper provides a design method based on MBSE using SysML to build up system/product architecture of High Lift System installed on aircraft from capturing demands of stakeholders to final system/products, which also considers effects on establishment of system/product taken safety as an example. This step-by-step design method can make system design and design process clear and reliable, and provide favorable support for the future validation and verification of High Lift System installed on aircraft.
