Historically, designers have often relied on empirical equations to estimate the structural weight during early stages of a design due to the lack of robust and fast structural layout tools. This reliance on estimating equations is obviously problematic for atypical or novel designs that do not align themselves well with historical data. Conversely, the M4 Structures Studio (M4SS) software package is a physics-based structural modeling tool capable of rapidly defining aircraft structural layouts with a parametric relationship to a geometry model. The following effort outlined in this paper demonstrates the ability for M4SS to interface with geometric models developed within the Engineering Sketch Pad (ESP) framework. The interface relies on geometric attribution to drive semi-automation of the structural layup, all while preserving parametric connectivity between the structural and geometric models. This parametric connectivity allows a designer to morph the structural model by simply making changes to the parameters defining the vehicles outer model line. This interface and integration is demonstrated on both generic transport and fighter models. 收起
