A toroidal propeller is a type of propeller that is ring-shaped. Toroid propellers are significantly quieter (especially at audible frequencies, which lie between 20 Hz and 20 kHz), and are claimed to be more efficient than traditional propellers both in air and water. Toroidal propellers are promising for their potential to reduce noise pollution through quieter aviation and maritime transport, but they have always been difficult to manufacture and therefore very expensive.

The model is made in high-poly style, which means that it has a lot of detail. It includes all the main elements of a toroidal propeller, such as:

The hub The blades The mounting holesAdditional details:

The model is designed to be printed on a 3D printer with a build volume of at least 10 cm x 10 cm x 10 cm. The model is made of a durable plastic material.

Applications:

Toroidal propellers can be used in a variety of applications, including: UAVs Drones Model airplanes Small boats

The outer diameter is 144 mm, and the diameter of the hole is 6.5 mm. A particular model has two toroidal propellers.
