Collins Aerospace, an RTX business, has been chosen to lead the PHEDRE consortium (Projet de modules Hélices Economiques, DuRables pour l’Environnement). An initiative focused on the development of advanced design methods and tools for next-generation turboprop propellers. With a focus on reducing noise, weight and aerodynamic impact, the consortium brings together teams of leaders across Collins Aerospace and outside entities to address critical aircraft efficiency technological barriers while enhancing passenger comfort and reducing the impact of propeller noise.
Jean-Francois Chanut, vice-president and general manager of propeller systems at Collins Aerospace, said: “Through PHEDRE, we will push the boundaries of innovation, aiming to deliver next-generation propeller technologies that enhance performance and efficiency for our customers. The PHEDRE programme is a strong example of synergy and innovation, supported by the French government, to drive progress in the aerospace industry, reinforcing the importance of local and international collaboration in advancing aerospace technologies.”
The initiative will focus on three key objectives. The first is developing design methods and tools that will optimise propeller configurations based on criteria such as noise reduction, aerodynamic efficiency, weight, complexity and manufacturing cycle time. Also, enhancing simulation capabilities by improving the understanding and simulation of physical phenomena associated with propeller operation, and thereby enable precise design and sizing. The third aspect will be implementing value-driven initiatives to enhance service capabilities and meet the high expectations of propeller operators.
Mr Chanut added: “With propeller systems playing a key role in the evolution of turboprop platforms, PHEDRE underscores Collins Aerospace Ratier-Figeac’s leadership in research and development within Europe. The initiative builds on the business’s legacy of innovation and its commitment to delivering technologies that drive performance improvements. In December 2025, Collins Aerospace was selected by the French Civil Aviation Authority (DGAC) for a France 2030 grant to lead the consortium over the next three years.”
Ratier-Figeac, affiliated with Collins Aerospace, is a ‘world leader’ in the design and manufacture of aircraft propellers. The company equips the Airbus A400M Atlas of European forces, the Atlantic 2, the C130H Hercules of American and international forces, the Airbus C295 and the ATR worldwide.
