Thanks to H3PS, we have further enhanced our capability in the development of all- electric and hybrid-electric power and propulsion systems for aviation. Our Hungarian colleagues are part of an international team to revolutionise aviation. We are focused on projects such as the development of an all-electric propulsion system for an eVTOL (electrical Vertical Take-Off and Landing) aircraft. Rolls-Royce is committed to achieving sustainable carbon neutral aviation" said Dr. Gergely György Balázs CEO of Rolls-Royce Hungary.
“The first successful maiden test of the H3PS aircraft is an incredible achievement of the Hungarian Rolls-Royce team in the development of a hybrid-electric flight. The programme has demonstrated our ability to design, manufacture, and install a fully integrated system and has provided us with valuable data and experience in hybrid-electric flight. The knowledge we gained will be used in future international projects to create higher performance hybrid-electric propulsion systems capable of powering a 19-seat commuter aircraft” said Zoltán Koltai, Head of Manufacturing of Rolls-Royce Electrical.
The 30 kW electric machine installed on the aircraft works as the starter-motor to start the combustion engine. During take-off and climb it is a thrust booster-motor adding extra torque to the propeller shaft. In the air, when the aircraft is cruising, it operates as a generator and converts the shaft movement into electric energy to re-charge the batteries.
As the electric motor contributes to the aircraft propulsion, the combustion engine can be reduced in size. For the Tecnam P2010, the 180 hp standard engine has been replaced with a smaller engine with only 141 hp. The reduction in engine size reduces fuel consumption and has further benefits. It also means the aircraft can go further on its existing fuel tank, and because the engine is always running at its optimal operating level it is more efficient and experiences less wear and tear, resulting in reduced maintenance costs and ultimately a lower cost of ownership.
The H3PS project was launched in 2018 and has now reached its objective. The success of the collaboration also strengthens the long-term cooperation with Tecnam as the two companies joined forces to deliver an all-electric passenger aircraft for the commuter market. This is another demonstration of Rolls-Royce developing the technology and the capability to be the leading provider of all-electric and hybrid-electric power and propulsion systems for Advanced Air Mobility.
