The Dpulsar system is a counter-rotating propeller system that can operate on the water line. Barry Davies, a New Zealand inventor, invented this system that bridges the technology gap between propellers and waterjets.
Highlights:
- The Dpulsar system has been trialled on U.S. designed and built Motus Motorbike engine.
- Lancer Marine(Auckland) designed the hull, especially for this project.
- It is claimed to be highly efficient in all its speed ranges.
- There are two contra-rotating helical style propellers within a tube.
- The water is sucked into an under hull grate and pushed out the stern in a solid mass.
- The nozzle does not accelerate the high mass output, as in waterjets.
- It is extremely safe for water-animals and humans as well.
