Toroidal propeller for drones and planes 3D print model

A toroidal propeller is an innovative propeller design that features a ring shape resembling a torus. Unlike traditional propeller propellers that rotate around an axis, toroidal propellers rotate in a plane perpendicular to the axis. This toroidal propeller model is built based on mathematical models. Both geometric twist and aerodynamic twist (three cross-sectional profiles) were used for best performance. There are two options, clockwise and counterclockwise.

Advantages:

Higher efficiency: Toroidal propellers are more efficient than traditional propeller propellers at converting torque into thrust. Quieter operation: Toroidal propellers are quieter than traditional propeller propellers because they do not generate vortex noise. Safer: Toroidal propellers are safer than traditional propeller propellers because they are enclosed in a ring. More compact: Toroidal propellers are more compact than traditional propeller propellers, making them suitable for confined spaces.

Disadvantages:

More complex constuction: Toroidal propellers are more complex to manufacture than traditional propeller propellers. Higher cost: Toroidal propellers are more expensive than traditional propeller propellers. Limited thrust: Toroidal propellers cannot generate as much thrust as traditional propeller propellers.

Where it can be applied:

Toroidal propellers are suitable for various applications, including:

Drones: Toroidal propellers are quieter and safer than traditional propeller propellers, making them suitable for drones used near people. Fans: Toroidal propellers are more efficient than traditional propeller propellers, making them suitable for fans used for heating and cooling. Airbags: Toroidal propellers are safer than traditional propeller propellers, making them suitable for airbags used to protect people and objects.

Future:

Toroidal propellers are a new technology with the potential to replace traditional propeller propellers in many applications. With the development of technology and manufacturing, toroidal propellers are becoming more affordable and efficient.
