I recently came across an article in a German model publication about what I am calling a vector thrust submarine.
They call the model the Ironfish. Kind of a steam punk design.
The cool thing I liked was the way they apply the power to the water.
It is like a two axis outdrive or vectored thrust.
I find this system totally intriguing and have to design my own version.
Here are some photos I pulled from the PDF using the iPad snapshot function.
The one model they call the Rocket.
I like rockets!
