OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao.univ-toulouse.fr/ Eprints ID : 18240 The aim of the project is to develop efficient capabilities (methods, tools and a software platform) to enable industrial deployment of MDO methods in industry. At IRT Saint Exupéry, industrial and academic partners collaborate in a single place to the development of MDO methodologies; the advantage provided by this mixed organization is to directly benefit from both advanced methods at the cutting edge of research and deep knowledge of industrial needs and constraints. This paper presents the three main goals of the project: the elaboration of innovative MDO methodologies and formulations (also referred to as architectures in the literature 1 ) adapted to the resolution of industrial aircraft optimization design problems, the development of a MDO platform featuring scalable MDO capabilities for transfer to industry and the achievement of a simulation-based optimization of an aircraft engine pylon with industrial Computational Fluid Dynamics (CFD) and Computational Structural Mechanics (CSM) tools.

The aim of this paper is to present a new model library developped as a new test case to benchmark optimization algorithms and Multidisciplinary Design Optimization (MDO) formulations. It introduces the MARILib software (Multidisciplinary Airplane Research Integrated Library). MARILib's first objective is to provide models for research on a wide range of aircraft concepts, from business jets to super jumbos, and also some unconventional configurations, through an Overall Aircraft Design (OAD) approach. The second objective is to share a new benchmark test case for MDO strategies, which does not raise intellectual property issues. The third objective is to describe a case study for educational and training purposes. MARILib will be available as Open Source.

In this work, we integrate a mission analysis algorithm into the Multidisciplinary Airplane Research Integrated Library (MARILib), which is a multidisciplinary optimization tool for aircraft sizing. The main purpose of such an integration is to include aircraft operational data from the initial design process, to develop a more realistic aircraft design framework. With this approach, the design and mission requirements that reflect how aircraft actually operate are considered in the design process. Mission analysis tools are developed to model realistic aircraft operations. Data analytics, including clustering algorithms, is performed to extract information from flight data, which then becomes input to MARILib. The aim of the framework is to reduce operational costs of aircraft starting from the initial design itself, by incorporating air transportation data into the conceptual design stages.
