The patented “Hexa-Tetrahedron propeller (HTP)” is an innovative alternative for ship propellers, turbines and pumps. The Hexa Tetra technology consists of 24 Equilateral triangles forming 6 tetrahedrons linked together in a Bricard ring forming an object in 3D with some intriguing geometric properties. The Hexa Tetra can twist within itself and it will propagate through its medium if the internal rotation could be achieved by an internal or external driving force.
All conventional propellers and centrifugal pumps work on the basis of rotating the fluid (water, air or any other liquid or gas) about an axis. The propeller blades maintain a certain “attack angle” with the fluid which causes thrust and torque. The torque (or swirl) is the rotational force on the fluid. The swirl does not contribute to the propulsion force and is lost energy. The swirl losses depend on the diameter and rotation speed and are practically 30-70%.
