Collins Aerospace, an RTX business, has launched the PHEDRE consortium in Figeac, France, to develop advanced design methods and tools for next-generation turboprop propellers. The initiative targets reductions in noise, weight, and aerodynamic impact to boost aircraft efficiency and passenger comfort.
PHEDRE (Projet de modules Hélices Economiques, DuRables pour l’Environnement) unites Collins Aerospace teams with external partners. It addresses key barriers in propeller technology amid rising demand for sustainable turboprops.
The program pursues three objectives: innovative design tools optimizing noise, aerodynamics, weight, complexity, and manufacturing; enhanced simulations of propeller physics for precise sizing; and upgraded services for operators.
Selected by the French Civil Aviation Authority in December 2025 for a France 2030 grant, Collins will lead over three years. This aligns with RTX efforts in related programs like PHARES and DEMETRA, where Collins advances propellers for hybrid-electric regional aircraft.
Ratier-Figeac’s leadership reinforces Europe’s R&D edge in propellers, critical for lowering operating costs and noise in evolving turboprop platforms.
