DEFAINE travels to Orlando for dissemination: AIAA SciTech 2024

Updated: Jan 31

From 8th till 12th of January, in Orlando, Florida, the AIAA SciTech conference took place, which is the largest event for aerospace research, development, and technology in the world. TU Delft presented a paper on a model-based approach for architectural design space exploration and optimization based on so called dynamic MDAO workflows, one of the technologies developed within DEFAINE. The full paper is: Model-Based Approach for the Simultaneous Design of Airframe Components and their Production Process Using Dynamic MDAO Workflows

The paper proposes a new methodology to address design for manufacturing as an architectural design optimization problem. The proposed methodology consists of three main steps. First, the architectural design space model of the component to be manufactured is extended to include decisions related to material, manufacturing and assembly options. In the second step, all product and production requirements are modelled and a verification method is assigned to them. Finally, in the third step, a dynamic MDAO workflow is formulated. A dynamic workflow is a workflow in which the design variables, analysis tools and constraints change during the optimization process. This allows for the trade-off between different manufacturing methods within one optimization workflow, which is demonstrated to be more efficient and effective than the formulation and execution of multiple static optimization workflows, each one specific to one architecture design option.

The methodology has been demonstrated through an application to the design and manufacturing of a wing rib. Results showed that the dynamic workflow was able to find the same Pareto front as its equivalent static workflows combined, while 16% faster! This is a promising result as one can expect this benefit to grow further for an increasing number of considered manufacturing and assembly methods.

The presentation at SciTech was well attended and received, leading to interesting discussions during and after the Q&A session. A copy of the conference paper can be found in the TU Delft repository or in this webpage. The slides for the presentation are available here.
