Neptuno is a technological implementation of a number of biological systems for moving in water. The goal of the project was to make it possible to move in water naturally. Neptuno’s propulsion system and steering are achieved using three pneumatic fins. This configuration facilitates maneuverability and quiet movement under water.
If you watch conventional submarines designed for use in maritime research, then they evidently have weaknesses as regards drive systems and controls. A fin propulsion system provides a very efficient and extremely quiet form of locomotion. Even though several research institutes are developing fin-propulsion systems, little has been done in order to combine these results with a Design of a full-scale submarine.
Every maritime biological being has passed through various stages of adaptation in the course of its evolution. Thus optimization to different living conditions eventually led to various forms and characteristics. Neptuno is the materialization of all these swimming characteristics to make a fin propulsion possible in these submarines.
Based on the understanding of the relantionship between form, movement and behavior of various fishes, the desired concept would have to permit changes in order to always reach optimum capacity relative to the conditions under which it has to operate. The use of Festo Pneumatic Muscles in a tri-dimensional configuration would allow the propulsion system to mimic different behaviors maximizing efficiency when needed.
