Toroidal Propellers for Efficient and Sustainable Aviation

The Vision:
​TorPropel is a transformative research and innovation action funded under the EIC Pathfinder Open programme. At its core is a radically new propulsion concept: toroidal propellers. Unlike conventional blade designs, toroidal geometries offer a leap in aerodynamic performance, enabling quieter, cleaner, and more efficient air travel —particularly in the growing landscape of electric, urban, and vertical aviation.


What We Aim to Do:
Over 36 months, the TorPropel consortium will research, develop, and prototype a new generation of propellers that combine:
​
-
Superior thrust performance
-
Advanced carbon fibre composites
-
Sustainable, recyclable materials (Vitrimers)
-
Robotic manufacturing and process automation
-
Real-time condition monitoring systems embedded in the structure
This initiative is not only a technical challenge—it’s a bold move toward the decarbonisation and digitalisation of short-range aviation.

Innovation & Technology

Key Technological Pillars:
​
-
Toroidal Propeller Geometry: A closed-loop design significantly reduces vortex shedding and improves acoustic performance.
-
Advanced Composite Materials: Use of carbon fibre-reinforced polymers, with recyclable and repairable vitrimer resins.
-
Robotic Manufacturing: Integration of Rapid Tow Shearing (RTS) and other automated manufacturing techniques to enable high-precision and scalable production.
-
Structural Health Monitoring (SHM): Embedded sensing systems for real-time monitoring, damage detection, and predictive maintenance, enhancing safety and reducing lifecycle costs.
-
Sustainability & Lifecycle: Every stage, from design to dismantling, is engineered for circularity, aligning with EU Green Deal ambitions.
