Hydrodynamic Sonar System

8ft forward-facing hydrodynamic sonar mounting system for Navier's hydrofoil electric boats.

As the Engineering Project Manager for Navier, I lead the development of a forward-facing hydrodynamic sonar system for their boats. I advised all designs, optimizing for 3D printing and marine use while allowing my team creative freedom.

Taken from our Final Deliverable:

On top of organizing tasks for my team of 4 engineers, communicating with Navier on project deadlines, and leading design reviews on all subsystems, I lead the manufacturing of the entire sonar system.

I 3D printed 55+ parts amassing 5+ kg of filament, ensuring designs were optimal for 3D printing. This involved teaching my engineers design for additive manufacturing and also revising their designs to be more structurally rigid for 3D printing.

I also designed a quick slot mounting system for the sonar, honing my DFAM skills as I machined every part of the system.

Our engineers performed ANSYS Fluent simulations on fairing designs for the sonar and the mounting system, achieving a drag coefficient <.05 for all designs. Given these drag coefficients, I was able to hand-calculate the forces acting on parts of the sonar system to ensure that our system was rigid and that our mount was strong enough for its application.
