The toroidal propeller, due to its unique structure, exhibits enhanced propulsion efficiency and reduced underwater noise. To investigate its operational mechanism, the hydrodynamic performance of the ...

Aura, an AI-powered virtual co-pilot, unveiled by Dassault Systèmes SolidWorks at the 3DExperience World event in Houston, Texas, is set to revolutionize the CAD design experience.

In the post-war glow of the late 1940s, Pan Am shocked the world with news that it had placed an order for a truly insane aircraft - taller than a five-story building and with six propeller ...

By changing the shape of a propeller design, we may have found a way to make drones (and a lot of other things that use propellers) not just quieter, but way more efficient.

This revealed some stalling on the bi-blade and the toroidal design too, which would explain some of the performance loss. Going back between the CAD model and the design in the patent by Sharrow ...

For example, digital models have been utilized to explore noise reduction using toroidal propellers, facilitating faster development and implementation of noise-reducing technologies.

Refining the shape In 2017, researchers at MIT filed a patent for toroidal propellers. Their patent claims the invention is more efficient than traditional propellers and is less noisy. Coincidentally ...

The reason toroidal propellers may be quieter is because of their complex shape – it minimises the strength of the vortex (a spiralling movement of air, water, or another fluid) that naturally ...

What is a 'toroidal propeller' and could it change the future of drones? An expert explains Abdulghani Mohamed, Senior Lecturer in Aerospace Engineering, RMIT University 12 June 2023 at 9:54 pm·4 ...

Comparing a well-designed toroidal propeller to a poorly designed traditional propeller will show a significant improvement, but is not a fair comparison. Well-designed toroidal propellers may have ...
