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. Nomenclature Without special notice, all units are international standard units. (.) f an = quantity related to the fan (.) Fr ee Str eam = quantity related to free stream (.) hybrid = quantity related to the hybrid architecture (.) I nlet = quantity related to the inlet (.) jet = quantity related to the jet (.) 0 = quantity related to reference turbofan without hybridation δ 0 = theoretical boundary layer thickness around a cylindrical fuselage of length L δ 1 = assessed boundary layer thickness around the e-fan hub δ = boundary layer thickness η eF = "propeller like" e-fan efficiency η C = wire conductivity efficiency *
