چکیده
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.

On The Construction of Aircraft Conceptual Geometry for High-Fidelity Analysis and Design
This paper examines the desirability and the challenges of incorporating high-fidelity geometry definition into the Multidisciplinary Design, Analysis and Optimization (MDAO) process earlier than currently practiced. A major objective is the ability to enable geometry definition for low-fidelity as well as high-fidelity analyses, in order to support the entire MDAO process from conceptual to de...
متن کاملAn unstructured quadrilateral mesh generation algorithm for aircraft structures
Because commercial aircraft are built with thin-walled structures, their structural performance is well-modeled using shell-element meshes. However, creating these meshes for the full aircraft configuration can be challenging and presents a bottleneck in the design process, especially in a configuration-level design space. This paper presents an algorithm that automatically creates unstructured...

A rapid geometry engine (RAGE) has been developed to allow for preliminary design analysis without labor-intensive CAD support. The geometry tool builds complex aircraft configurations using a component-based approach. Basic algorithms for creating the primary components are presented and discussed. Examples of many widely varying geometry models are shown. A select geometry model is analyzed w...
متن کاملAdvantages of an Integrated Simulation Environment
Numerical simulation software in the field of aircraft design can be classified as first, second or third generation Multi-Disciplinary Analysis and Optimatzion (MDAO) system. The most challenging task nowadays is to create a third generation MDAO because there are no good-practice rules how to create a useful software system. The prerequisite for a successstory of such a software is a successf...
متن کاملStructrual and Multidisciplinary Optimization A Graph Theoretic Approach to Problem Formulation for Multidisciplinary Design Analysis and Optimization
The formulation of multidisciplinary design, analysis, and optimization (MDAO) problems has become increasingly complex as the number of analysis tools and design variables included in typical studies has grown. This growth in the scale and scope of MDAO problems has been motivated by the need to incorporate additional design disciplines and to expand the parametric design space to enable the e...
