摘要

Top Down is a very well known design methodology in systems engineering, allowing to manage complex systems by creating a hierarchy of information with an increasing level of detail, the result is a structure able to capture the significant parameters of the system. When it comes to CAD, parametric and associative modeling are topics widely known as well, since a vast offer of commercial products able to support these kind of features is available. The point is to put this two concepts together in order to achieve an effective methodology able to implement Top Down modeling in a real parametric and associative CAD environment. The goal of this paper is to show how a Top Down Design Methodology for a Low Pressure Turbine has been developed at Avio implementing a Control Structure as the backbone of the CAD Design process. Moreover, it will be shown how the Master Model obtained from a Control Structure has been integrated into the analysis loops.
