Tecnam unveils their hybrid-electric technology demonstrator with Rolls-Royce and Rotax propulsion system
With the call to make flight more sustainable and environmentally friendly, comes the need for propulsion systems that enable reduced fuel consumption and emissions – without compromising aircraft endurance and performance.
Together with the Italian aircraft manufacturer Tecnam and the Austrian engine producer BRP-Rotax, Rolls-Royce has been developing a prototype parallel-hybrid electric powertrain to achieve exactly that. The companies joined forces on the “H3PS” project in 2018, under the framework of a European Horizon 2020 fund. H3PS encompasses three ‘Hs’: ‘high power’, ‘hybrid powertrain’ and ‘high-scalability aircraft’, and involves equipping a 4-seat Tecnam P2010 with a parallel-hybrid electric powertrain – believed to be the first of its kind ever developed for general aviation – to help reduce fuel consumption, while maintaining and even extending aircraft range. The project introduces advanced technology for a smaller power class, while being scalable for larger general aviation aircraft.
The project has successfully tackled the challenges presented by parallel-hybrid electric architectures, with the purpose of de-risking a technology that is novel to aerospace propulsion applications and to further mature it into a commercially viable solution. Rolls-Royce has been responsible for the electrical part of the parallel-hybrid electric propulsion system. A Rolls-Royce Electrical team based in Budapest, Hungary, developed the 30 kW electric machine, electric controls and the complete battery system.
