1. Pratt & Whitney Canada leads EU's Clean Aviation PHARES project. 2. The initiative focuses on hybrid-electric propulsion for regional aircraft. 3. Targeting up to 20% improved fuel efficiency through advanced technologies. 4. Collaboration includes industry leaders like Collins Aerospace and Airbus. 5. Supports EU's climate ambitions for decarbonization in aviation.
Leading a high-impact project enhances RTX's reputation and growth potential, similar to Boeing's profitable ventures in aerospace innovation.
Engagement in Clean Aviation marks RTX's innovation leadership, which likely boosts investor confidence.
The project's duration suggests benefits will accrue over time, resembling past successful launches in hybrid tech by GE Aviation.
Selection marks the first time a Canadian company will participate in and lead a Clean Aviation program
LONGUEUIL, Quebec, Sept. 9, 2025 /PRNewswire/ -- Pratt & Whitney Canada, an RTX business, has been selected by the European Union's Clean Aviation Joint Undertaking (Clean Aviation) to lead the Powerplant Hybrid Application REgional Segment (PHARES) project. The selection marks the first time a Canadian company will participate in and lead a Clean Aviation program. As part of the PHARES consortium, Pratt & Whitney Canada will collaborate with RTX business Collins Aerospace, ATR, Airbus and other technology research organizations. PHARES is one of several projects RTX will participate in under Clean Aviation's third call for proposals.
For PHARES, Pratt & Whitney Canada will design and integrate a hybrid-electric propulsion demonstrator targeting up to 20% improved fuel efficiency on regional aircraft missions. The hybrid-electric propulsion system will feature an advanced PW127XT-derivative turboprop engine connected to a Collins 250 kW electric motor drive system through an optimized propeller gearbox and incorporate thermal efficiency improvements. Collins will also develop an advanced propeller system to improve fuel efficiency and reduce noise.
"Hybrid-electric propulsion and electrified aircraft systems are key parts of RTX's technology roadmap for optimizing performance and enhancing fuel efficiency across multiple future aircraft platforms, and PHARES represents a transformative opportunity to demonstrate the potential for regional aviation," said Maria Della Posta, president, Pratt & Whitney Canada. "Through our Pratt & Whitney Canada and Collins businesses, we will leverage our industry-leading experience in propulsion and electric power systems, along with our state-of-the-art research facilities."
PHARES is part of Clean Aviation's Ultra-Efficient Regional Aircraft architecture. By enabling next-generation energy-efficient technologies for regional aircraft, this demonstrator is aligned with the European Union's climate action plan and supports the aviation industry's decarbonization ambitions.
About Clean Aviation
The Clean Aviation Joint Undertaking is the European Union's leading research and innovation programme for transforming aviation towards a sustainable and climate-neutral future. It is a successful European public-private partnership between the European Commission through Horizon Europe, the EU research and innovation programme, and the European aeronautics industry. It has a budget of €4.1 billion divided into €1.7 billion in EU funding and no less than €2.4 billion in private funding. The programme's disruptive clean aviation technologies will help reduce the emission footprint of short-medium range and regional aircraft by no less than 30% compared to 2020 state-of-the-art aircraft. Clean Aviation builds on the knowledge and expertise of the Clean Sky programmes (2008-2024).
