TECHNOLOGY How Will Airbus and Rolls-Royce's New Hybrid System Change Aviation?

Airbus and Rolls-Royce are collaborating on a new hybrid-electric propulsion system to boost fuel efficiency and significantly reduce commercial aviation's environmental impact.

Key Points

1The collaboration focuses on a hybrid-electric propulsion system to enhance fuel efficiency and cut emissions.
2Rolls-Royce is developing a scalable turbogenerator, a core component, with a small gas turbine completing its first fuel burn in 2023.
3The new system is designed to be compatible with Sustainable Aviation Fuels (SAF), supporting the industry's net-zero goals.
4Major challenges include achieving optimal power-to-weight ratios and establishing new regulatory standards for electric flight.

The aerospace giants Airbus and Rolls-Royce are teaming up. They plan to develop a new hybrid-electric propulsion system for future commercial aircraft. This collaboration aims to significantly improve fuel efficiency technology. It will also help in reducing environmental impact from air travel.

Advancing Hybrid-Electric Propulsion Development

This new partnership builds on years of joint research. The companies previously worked together on the E-Fan X demonstrator project. That program successfully tested a serial hybrid-electric propulsion system. It helped define the possibilities and limits of this new technology.

Rolls-Royce has been developing key components independently. This includes a scalable turbogenerator technology. This system is designed to act as an on-board power source. It can power electric motors directly or recharge batteries in flight. The turbogenerator is being scaled to serve power ranges between 500 kW and 1200 kW. A smaller gas turbine for this system completed its first fuel burn in 2023. This technology is vital for future aircraft propulsion system designs.

Key Technology Focus

Turbogenerator Integration: Rolls-Royce will focus on the gas turbine and generator. This creates the necessary electric power.
System Architecture: Airbus will handle the overall system integration. This includes the aircraft’s control architecture.
Scalability: The goal is a system that can power regional aircraft. It may later be scaled up for larger commercial jets.

Impact on Sustainable Aviation

This joint effort is a major step toward net zero emissions in the industry. Hybrid-electric power offers a path to lower carbon output. It is seen as a crucial medium-to-long-term solution.

Airlines stand to benefit from lower operating costs. The new system promises better fuel burn efficiency. This is achieved by using electric power during certain flight phases. Furthermore, the turbogenerator is designed to run on sustainable aviation fuels (SAF). Using SAF can reduce lifecycle CO2 emissions by up to 80%. Airbus and Rolls-Royce already collaborate heavily on SAF adoption. They are pushing for 100% SAF certification for their existing engines.

Challenges and Regulatory Hurdles

Developing this technology faces significant challenges. The power-to-weight ratio of components is critical. Hybrid systems must be lightweight and compact to be competitive.

Regulatory bodies like EASA and the FAA must also adapt. New certification standards are needed for electric and hybrid-electric aircraft. The development process will help create a foundation for electric aircraft certification. This will pave the way for wider adoption of alternative-propulsion commercial aircraft.

This partnership reinforces the industry's commitment. It shows a dedication to aerospace decarbonization efforts. This work will shape the future of air travel for passengers and operators globally.
