1: 40 scale dynamic-diving model of the German Federal Navy’s 212-class submarine When we decided it was time to produce a new model submarine, our development team selected the new, ultra-modern 212- class of the German Federal Navy as their prototype. The full-size boat: These subs were developed at the Howaldtswerke-Deutsche Werft Gmb H (HDW) dockyard in Kiel. It is the world’s first submarine type to be equipped with a hybrid fuel cell power system. Basically the boat is propelled by an electric motor. For surface running the motor is powered by a diesel generator, but when the boat is submerged, electrical current is supplied by a hydrogen fuel cell system. U 31 was the first 212 A class to be built, & the vessel was launched in March 2002; this is the basis for our model. The model: Our model of the U 31 has been developed & built using proven methods of construction & pre-fabrication, i.e. the same methods used on the U 2540. However, the diameter of the pressure vessel has been increased by 3.5cm in order to give the large hull the stiffness required. The pressure vessel is fitted with an internal multi-part CNC-machined installation frame, which houses all the essential RC & electrical system components. Just like the full-size sub, our model of the U31 features an ultra-modern power system: in this case a slow-rewing, high-torque brushless electric motor provides enormous thrust. With the kind approval & support of the Howaldtswerke-Deutsche Werft Gmb H (HDW) of Kiel. Specification: Length: 1430 mm
