The undulation motion is entirely dependent on the materials, waveform parameters, and morphology of the fins. Therefore, each parameter was thoroughly analyzed and selected based on efficiency, optimal thrust, dimensional analysis, and success of previous researchers. Our initial calculations and findings have led to the following parameters:


As for the morphology of the fins, the shape will be based on the Dasyatis Americana (a.k.a the Southern Stingray). This species of stingray shares similar parameter values and overall size to those chosen for the Silent Submarine – and therefore, it was chosen as the model species stingray for this project.



To clarify, a rubber latex sleeve will be fitted onto the fin rays. Rubber latex is a smooth, flexible material that will enable the proper undulating motion of the submarine.
You article definitely has all the information and facts I needed about this subject. I didn’t know who to ask, so thank you kindly…
