This paper presents GeoMACH: Geometry-centric MDAO of Aircraft Configurations with High fidelity. GeoMACH is an open-source aircraft design tool suite under development that is planned to support MDAO with a large number of design variables. First, the overall GeoMACH architecture is described, including a proposed method for streamlined data transfer between disciplines. GeoMACH’s efficient and lightweight B-spline engine is then introduced as it forms the basis for the geometry-centric approach to MDAO. Next, GeoMACH’s OML and structural modelers are presented, which provide parametric aircraft modeling tools that span a configuration-level design space.
