Global Model of Aircraft Design: from Performance Requirements towards Architectures Optimization
Résumé
Systems engineering is a transdisciplinary approach that seeks the successful realisation of a system. In order to reach that, it is necessary to satisfy a series of needs and stakeholders, which have to be defined as a group of requirements to be fulfilled. Design approaches such as MDAO, MBSE, and MBSA have been created to help better designing aircraft in different aspects. However, there has never been an aircraft design method which combines all the mentioned design approaches and that, nowadays, has an increasing interest in the industry. Therefore, the paper aim is to produce aircraft design tools and methodology which link all the three design approaches together by using a surveillance UAV as a study case. As a part of the MDAO-MBSE global project, a MDAO model has been developed using a web application (WhatsOpt) and a MDAO platform (OpenMDAO) on Python, while the tool considered to develop the MBSE model is Eclipse Papyrus, a powerful tool that allows to use XML for export their models. Some promising results show the coupling between MDAO and MBSE based on XML file exchange.
