Abstract

The Systems Engineering provides some suitable tool for an effective description of the functional behavior of systems and of their architecture,but a detailed design activity needs for a quantitative investigation,which is typically based on some set of equations,including the main design parameters. The test case here shown concerns the modeling of a de–icing system for a regional turboprop,being a public use case developed within the frame of the CRYSTAL project.The description of the system architecture within the SysML language is done by means of Rhapsody through Use Case Diagrams(UCD), Internal Block Diagrams(IBD) and State Machine Diagrams(STM),after a Requirement Analysis(REQ) performed in DOORS.A suitable integration with the physical model of the de-icing system in the Simulink environment allows a suitable refinement of requirements, an assessment of the system configuration as well as the detection of the most critical issues of the design of such system. A complete description of all the phenomena occurring in operation is given by numerical models thus,in addition to the architecture of the system identified through a SysML functional analysis and a design synthesis,a physical model of the de-icing system developed in Simulink is associated. The functional model is used to define the components to be included into the system and the layout most compatible with the functions required.The physical model is suitable to investigate the system dynamic behavior through a time-dependent numerical simulation. A strong cooperation between the two models is a current goal of the development of this engineering method,to reach a complete interoperability of tools for a simultaneous investigation which could reduce the time to develop the product and enhance the possibility of suitably relating functions,system components,interfaces and performances within a unique and integrated design environment.
