Dynamic Sonar Mount
Designed a dynamic mounting solution for a research sonar that enables seamless transition between operational and storage positions on a submersible truss system.
Overview
The Problem
Design and implementation of a mounting solution for a research sonar that attaches to the vessel's submersible sensor truss while avoiding beam interference during operation.
The Solution
Developed a compartmental, two-position mounting system with hydrodynamic design that allows secure transition between operational and storage positions.
Key Outcomes
- •Successfully implemented dynamic positioning system
- •Achieved interference-free sonar operation
- •Created durable design for marine environment
- •Simplified assembly and maintenance process

Design Challenges & Solutions
Sonar Beam Interference
Given the structure of the truss and surrounding components, there was no static solution where the sonar could rest safely within the boundary of the truss and operate without interference.
2-Position Track System
This led to the idea of a dynamic, two-position system. I created a system requiring only hand-tightening to transition between positions, eliminating the need for tools in offshore environments where items can easily fall overboard.
Environmental Durability
The mount needed to withstand extended submersion in both fresh and saltwater, as well as long-term storage. This inspired durable material selection including aluminum, corrosion-resistant stainless steel, and specialized Z-ULTRAT filament.
Compartmental Design
Implemented an easy-to-assemble design using bolted 3D-printed components with heat-inserts, enabling simple assembly, breakdown, and replication of parts as needed.
Additional Design Approaches
Hydrodynamic Considerations
Incorporated hydrodynamic design elements and strategic cutouts to minimize forces on the hardware during operation, ensuring durability and reliable data collection.
Impact & Results
Impact
The mounting solution enabled reliable sonar operation while solving key challenges of beam interference and marine durability, providing a practical solution for both operational and storage requirements.
Efficiency
Reduced installation time by 300% compared to previous solutions requiring removal and reinstallation
Usability
No tools needed during operation, improving offshore workflow
Durability
Withstood multiple deployment cycles with no performance degradation
