The European Union research project Novel Energy and propUlsion systeMs for Air dominance (NEUMANN), funded by the European Defence Fund (EDF) and led atUNISA by prof. Marco Sorrentino - DIIn, aims to address propulsion and energy systems technologies required for a highly efficient powerplant, able to deliver at the same time increased electrical power generation and increased thrust-to-weight ratio, which are necessary to cope with the mission requirements and operational needs of the next generation of fighter aircraft. The research consortium includes several leading European universities (e.g., Politecnico di Milano, Lund University, Czech Technical University, Univ. of Padua,UNISA), research centers (e.g., CIRA, CNR, Von Karman Institute), and aviation companies (e.g., Leonardo, GE AVIO).UNISA main contributions are the design and the energy management of fuel cell systems. The role of the members joining DIEM (prof. Addesso and prof. Postiglione) is related to the reliability assessment of the solutions proposed within the project, and statistical data analysis.
