Speed/Depth Recorder Project
2008
Duelley, Richard | Marks, Cynthia | Sander, Oliver
The team was given the task of designing an economical and effective sub-surface vehicle for measuring speed and depth. This device will be part of a towed array deployed behind a surface ship. The vehicle must deliver accurate measurements at depths of up to 1,000 feet, while remaining neutrally buoyant with a static trim of 0? or slightly nose down. The device had to be simple and easy to use and require little or no daily maintenance. The team developed a concept vehicle that met all the minimum requirements and exceeded some of the objective requirements. The vehicle contains an integrated stand-alone data logger and uses a combination of foam and free-flooded compartments to remain neutrally buoyant. The estimated fabrication cost is $8,200 per unit. Although the team demonstrated the feasibility of the concept, additional analysis is required to minimize risk and address aspects of the design beyond the scope of the team's mandate.
