Our previous alluminium design which was using curved flat plate was optimised for speed of 1m/s.
Due to much higher speeds obtainable with our DPV we redesigned this solution, using under-cambered airfoil, to allow for complete elimination of torque effect, in all speed ranges (created counterforce is proportional to water flow speed).
Special construction technology based on fiberglass reinforced polymers allowed also to decrease the total weight of this element by 300g, and make it almost neutral in water, for easiness of underwater scooter dismantling protocols. It also increased thrust by 2% compared to previous solution, at the same propeller RPM. This makes also Seacraft Future models weight only 15,9kg, ready to dive.
New post-swirl-stator is fully compatibile with older Seacraft units, and every scooter leaving the factory is now equiped with it.
Alluminium construction is still available on special order, when extreme mechanical resistance is required.
