Toroidal Propellers for Efficient and Sustainable Aviation

Introduction

The TorPropel aims to advance aircraft propulsion technology by developing and upscaling propellers of toroidal geometry, which are distinguished for their thrust efficiency and noise reduction, utilising advanced carbon composites and state-of-the-art robotic manufacturing processes.

Potential Impact

This technology has the potential to significantly improve the performance of propeller-driven aircraft, a distinct category of aviation platforms that includes:

1. Smaller, piston-driven or electric aircraft
2. Vertical take-off and landing aircraft (VTOLs)
3. Unmanned aerial vehicles (UAVs)
4. Aircraft based on novel design concepts, such as those featuring distributed propulsion systems

Material and Manufacturing Innovations

TorPropel sees the development of advanced, aerospace-grade carbon composites alongside the implementation of innovative robotic manufacturing solutions. This approach ensures:

• Achievement of critical performance objectives
• A lightweight profile
• Prioritisation of the propellers' recyclability and repairability

Condition Monitoring Systems

Moreover, the project incorporates sophisticated condition monitoring systems directly into the propeller structure. This is essential for:

• Real-time assessment of propeller structural health
• Ensuring safety
• Considerably reducing the time and costs associated with maintenance

Conclusion

Overall, the TorPropel technology is expected to offer significant improvements in propeller performance, durability, weight, sustainability, and recyclability. The proposed technology is thus anticipated to make a significant contribution to the scientific field of aircraft propulsion technologies, improving operational effectiveness and environmental sustainability in aviation. Additionally, it paves the way for a new era of short-distance air travel that is both quieter and environmentally friendly.
