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:

​

  1. Toroidal Propeller Geometry: A closed-loop design significantly reduces vortex shedding and improves acoustic performance.

  2. Advanced Composite Materials: Use of carbon fibre-reinforced polymers, with recyclable and repairable vitrimer resins.

  3. Robotic Manufacturing: Integration of Rapid Tow Shearing (RTS) and other automated manufacturing techniques to enable high-precision and scalable production.

  4. Structural Health Monitoring (SHM): Embedded sensing systems for real-time monitoring, damage detection, and predictive maintenance, enhancing safety and reducing lifecycle costs.

  5. Sustainability & Lifecycle: Every stage, from design to dismantling, is engineered for circularity, aligning with EU Green Deal ambitions.
