The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the U.S. Navy in Memphis since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air- or water-borne transportation systems. (Photo: U.S. Navy)

The chamber can be drained and opened to gain access to the test object, which can be changed to test difference shapes and configurations. “We can create different control surfaces through 3D printing,” said Brown.Right now the LCC is being used to characterize the performance of the propulsor for the Columbia-class ballistic missile submarine, the replacement for the Ohio-class submarines. “We built a scale model of the entire submarine and propulsor to measure everything from

(shown in Figure 3, on page 44), the initial design was determined to well exceed the threshold depth rating, which was then increased to 300 meters for the standard vehicle while maintaining an adequate factor of safety.Riptide utilized the latest methods of rapid manufacturing heavily relying on 3D printing or additive manufacturing in its early production deliveries. Riptide has recently procured injection resin molds for all 3D printed parts for the micro-UUV under a manufacturing grant from Massachusetts, but maintain the ability to 3D print any component for design flexibility.

well as support for the MOOS-IvP robot control engine. Future releases are planned to include support for ROS (the Robot Operating System) and streamlined user interfaces.   In addition to embracing current software development trends the micro-UUV has been developed using a large quantity of 3D printing. This has enabled affordable and quick evaluation of numerous design considerations. This rapid manufacturing capability has also enabled Riptide to quickly field production vehicles. This approach is not just for engineering models. It is delivering product capable of withstanding the pressures

Our hulls are a composite of Glass and Kevlar Fibers giving us excellent impact and structural strength; almost literally bullet proof! We have used SLS (Selective Laser Sintering) 3D printing to create intricate parts quickly and to extremely high tolerance which have been used in the production vessels to great effect. Putting electronics in saline environments has proved tricky, and we have had to design sub-sea housings to encase electronic components and assemblies to &lsquo

When It Comes to Inspiring Innovation, 'X' Marks the Spot

.   As technology gets faster, cheaper and smaller, a single individual can have access to things today that only the biggest governments had access to in the past. We are seeing exponential advances in sensor technologies, artificial intelligence, robotics, synthetic biology, virtual reality, 3D printing to name a few. Collectively, we are poised to be able to address some of the greatest challenges we face through these advances in technology. In keeping with innovations in other fields, marine technology has also been evolving rapidly and will continue to do so as more of these exponential technologi
