A Multidisciplinary Airplane Research Integrated Library With Applications To Partial Turboelectric Propulsion

Abstract : 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. 1.
