Modeling and Control of a Back-to-Back system for turboelectric propulsion

The air transportation industry contributes with 2% of the total greenhouse gas emissions, and there is a demand from global aviation regulators for reducing this percentage. Hybrid-electric propulsion systems (HEPS) for aircraft is an area of increasing interest for achieving these goals. It is a multidisciplinary research that involves internal combustion engines (ICE), electric motors (EM), power electronic converters, energy storage devices, propeller design, monitoring and control systems, management, etc. The Electromechanical Energy Conversion Group (GCEME) in Brazil developed a complete HEPS test bench and Laboratory. The facility will be able to test three different topologies: Series, full-electric and turbo-electric. The present work employs a detailed model for the test bench, and given a mission prole and the energy consumption as optimization function, it applies Dierential Evolution (DE) techniques in the energy management code. The results highlight the nonlinear nature of the HEPS model, and the worth of this methodology in looking for an optimal solution to reduce the computing processing time.

The present work is a survey on aircraft hybrid electric propulsion (HEP) that aims to present state-of-the-art technologies and future tendencies in the following areas: air transport market, hybrid demonstrators, HEP topologies applications, aircraft design, electrical systems for aircraft, energy storage, aircraft internal combustion engines, and management and control strategies. Several changes on aircraft propulsion will occur in the next 30 years, following the aircraft market demand and environmental regulations. Two commercial areas are in evolution, electrical urban air mobility (UAM) and hybrid-electric regional aircraft. The first one is expected to come into service in the next 10 years with small devices. The last one will gradually come into service, starting with small aircraft according to developments in energy storage, fuel cells, aircraft design and hybrid architectures integration. All-electric architecture seems to be more adapted to UAM. Turbo-electric hybrid architecture combined with distributed propulsion and boundary layer ingestion seems to have more success for regional aircraft, attaining environmental goals for 2030 and 2050. Computational models supported by powerful simulation tools will be a key to support research and aircraft HEP design in the coming years. Brazilian research in these challenging areas is in the beginning, and a multidisciplinary collaboration will be critical for success in the next few years.
