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.

“…The aviation sectors have even expensed about one trillion dollars in an attempt to reduce fossil fuel consumption by improving the fuel availability of engines [2,3]. Civil and military aircraft generally equip the aero engine based on the Brayton cycle, such as turbofan, turbojet, and turboprop engines [4,5]. Currently, the improvement of engine efficiency mainly depends on the increase of cycle pressure ratio and turbine inlet temperature.…”

The cooled cooling air technology (CCA technology) shows expected performance in solving the growing thermal challenge for advanced aero engines by reducing the temperature of cooling air. The effect of CCA technology on the overall propelling performance with or without adjusting cycle parameters is controversial. Based on this, both the energy and exergy methods have been adopted to elaborate the specific mechanisms of the above energy utilization discrepancy. As a result, the scheme of CCA technology without optimizing cycle parameters has lower propelling work and efficiency with the total exergy destruction increasing 0.5~2%. Oppositely, as for the scheme of CCA with meliorated cycle parameters, the propelling efficiency improved by around 2~4% with total exergy destruction reduced by 1~3.5%. By analyzing the distribution of exergy destruction, the avoidable and unavoidable exergy destruction caused by the combustion chamber, compressors, and turbines accounts for the largest proportion, which indicates that more attention needs to be paid in the future. During the whole flight mission, the percentage of exergy destruction is much higher in supersonic, subsonic cruise, combat, and escape conditions. In conclusion, the improvement of cycle parameters to reduce the exergy destruction should be considered when introducing CCA technology.

Investigation of Potential Fuels for Hybrid Molten Carbonate Fuel Cell-Based Aircraft Propulsion Systems

Alternative fuels and innovative powering systems are recognized as essential for clean and sustainable aviation practices, performance improvements and emission reductions. This paper proposes a new hybrid turbofan and molten carbonate fuel cell (MCFC) system consisting of a steam reformer, a water gas shift reactor, and a catalytic burner. Five potential fuels are employed, including ethanol, methane, hydrogen, dimethyl ether, and methanol with different mass fractions to constitute five fuel blends. Thermodynamic analyses are conducted to study the proposed hybrid MCFC-turbofan performance, and the results are compared with a kerosene-based turbofan. It is found that a traditional turbofan performance can produce 42 MW with 59% energetic efficiency and 71% exergetic efficiency, whereas the hybrid MCFC turbofan can produce 40 MW by mixing all the five alternative fuels, but with higher performance of 65% and 80% energetic and exergetic efficiencies, respectively. Also, the CO 2 emissions are substantially reduced by 75%. The fuel blends provide better performance and much lower CO 2 emissions.
