Hybrid Electric Regional Aircraft Concept for Low EmissionS

Project description

The future of regional flight

Aviation’s carbon footprint is becoming harder to ignore, especially in Europe, where regional flights make up over 20 % of all departures. This makes short-haul travel the ideal place to start the push towards net-zero emissions by 2050. The EU-funded HERACLES project aims to design a new, ultra-efficient regional aeroplane that moves beyond a single-fix solution. By combining hybrid-electric power and high-performance batteries with engines that run on 100 % sustainable fuel, and pairing them with a total redesign of the aircraft’s body and propellers, the project aims to cut CO2 emissions by at least 30 %. By focusing on technology that can be approved for flight quickly, HERACLES is expected to have these cleaner aircraft in the air by 2035.

Objective

In a world where the consequences of the climate change are already observable, the reduction of the aviation’s ecological footprint is undoubtedly essential. With 22% of total commercial flight departures being operated by regional aircraft, the introduction of more innovative concepts is necessary to achieving the net-zero carbon emissions by 2050 defined by the European Green Deal.
In this context, HERACLES aims to define an ultra-efficient regional aircraft (UERA) concept, embedding innovative technologies, such as a hybrid electric propulsion system with high-performance batteries and optimized thermal engine (using 100% SAF), optimized propeller, advanced airframe and other enabling technologies for more electric aircraft. This concept targets a reduction of no less than 30% in CO2 emissions on typical regional routes (250NM or below), compared to a 2020 state-of-the-art aircraft.
The project will benefit of a portfolio of demonstrations in regional thrust, to integrate technologies at high level of maturation (TRL5/6 at the end of the program), to support entry into service in 2035. The certification aspects will also take a major role in HERACLES. The project will coordinate the EASA involvement in all projects of the consortia (HERACLES, REG-01, REG-02 and REG-03), to contribute to the rulemaking for hybrid aircraft and deliver a route to CRL6. Furthermore, HERACLES will support the flight test demonstrator (FTD) assessment led by the REG-03 project, by providing the architecture and configuration assessment of fully integrated design of the demonstrator and the flight physics studies. It will also support the wind tunnel tests performed in this project by providing the design of the propeller and nacelle concept to be tested. With these activities defined for the UERA concept and the FTD, HERACLES will accelerate the penetration of innovative technologies in the regional aircraft market, to significantly participate to the aviation decarbonization.
