SystemXF: a novel approach for holistic system modeling in aircraft conceptual design

Abstract

In aircraft conceptual design, systems are typically represented by historical regressions without considering system architecture. For novel technologies, this is no longer possible. Alternative approaches are either hard coded solutions for special system architectures or lack the analysis capabilities necessary for conceptual aircraft design. The novel SystemXF approach intends to close this gap by providing a framework for system modeling that is not technology specific and allows for the integration of different analysis disciplines within a single model. A central XML file is used for system specification which can be edited using a SysML interface. A mass estimation and a safety analysis tool are available. An example system which is inspired by a real pitch control system is used to illustrate the method and to show the applicability. This modeling example shows that the proposed model is capable to represent and analyze realistic systems in conceptual aircraft design. The analysis tools can be used for system studies and to provide inputs for a conceptual aircraft design process.
