iRobot Seaglider

Terry Knight — Thu, 03 Sep 2009 14:00:00 GMT

The iRobot Seaglider is a deep-diving UUV designed for missions lasting many months and covering thousands of miles. Seaglider measures temperature, salinity and other quantities in the ocean, sending back data using global satellite telemetry. More than 70 Seaglider UUVs have been delivered worldwide, collecting ocean physical properties and performing various other missions for oceanographers, including the U.S. Navy, government agencies and research organizations.

GhostSwimmer AUV - Part 1

CurtisEllzey — Tue, 01 Sep 2009 14:02:00 GMT
GhostSwimmer is a tactical, efficient, biomimetic autonomous artificial fish UUV that employs the actual mechanics and dynamics of biological fish to create the ultimate in efficient swimming while remaining responsive to the needs of current covert, riverine, and littoral missions. It endeavors to attack problems facing current UUVs. A product of the combined experience of David Barrett (Olin College), inventor/developer of MIT's groundbreaking Robo-Tuna, and Mike Rufo (Boston Engineering), inventor/developer of marsupial underwater UUV/Crawler technologies, it mimics the actual motion of a tuna (one of nature's fastest and most maneuverable fish). Also watch this episode: GhostSwimmer AUV - Part 2. For more information, visit Boston Engineering.

Power Wave AC/DC 1000

CurtisEllzey — Tue, 19 May 2009 14:00:00 GMT
The Power Wave AC/DC 1000 inverter power source from The Lincoln Electric Company enabled T Bailey (a Washington-based construction and fabrication company) to significantly increase productivity and reach the higher deposition rates on its wind turbine towers. The machine’s patented Waveform Control Technology and variable AC/DC frequency allows for higher deposition rates at lower amperages compared to other available machines. It also provides a more stable arc for a consistent penetration pattern along the length of the weld, which is necessary in order for the welds to pass ultrasonic testing. Also watch this episode: Wind Tower Fabrication. For more information, go to: Lincoln Electric.

Wind Tower Fabrication

CurtisEllzey — Mon, 18 May 2009 14:00:00 GMT
Essential to wind power generation is fabrication of wind towers capable of enduring the extreme conditions in which they are placed. Environmental exposure and high quality material requirements are two of the many challenges presented in wind tower fabrication. Patrick Wahlen details how Lincoln Electric is tackling the challenge of tower construction using submerged arc welding to fabricate and connect the sections, or steel "cans", to provide for quick and efficient assembly in the field. All these steps require quality welds able to meet exacting test standards. Also watch this episode: Power Wave AC/DC 1000. For more information, go to: Lincoln Electric.

Paragon Dive System

CurtisEllzey — Tue, 28 Apr 2009 14:06:00 GMT
The Paragon Dive System isolates a diver in a “space-suit like environment”, incorporating a Return Surface Exhaust design and upgraded materials, completely protecting divers from contaminants and hazardous materials present in their surrounding environment. The US Navy funded Paragon to redesign their existing surface supplied diving system because of the health risks posed to divers operating in contaminated water environments such as the USS Cole incident and Hurricane Katrina. Also watch this episode: Constellation Space Suit. For more information, go to: Paragon Space Development Corporation.

Fire Scout UAV: Part 2

CurtisEllzey — Thu, 14 Aug 2008 06:11:00 GMT
Northrop Grumman's Fire Scout UAV is based on a commercial off-the-shelf Schweizer 333 manned helicopter manufactured in Horseheads, NY. The baseline design has proven a highly reliable and effective platform with extensive operating history. The Army plans to use Fire Scout for its Class IV Unmanned Air Vehicle within its Future Combat Systems program. The Fire Scout system allows for over-the-horizon targeting, communications relay, threat detection, intelligence gathering, precision strike support and real-time battle damage assessment. The Navy plans to use Fire Scout on board the Littoral Combat Ship, where sailors will operate both manned and unmanned helicopters to support operational requirements. These include real-time video imagery, intelligence gathering, communications-relay capability, precision targeting and battle damage assessment.

Microalgae Bioreactors

CurtisEllzey — Thu, 24 Apr 2008 14:23:00 GMT
Current research in the area of biofuels includes a major R&D program with Solix Biofuels and the Engines and Energy Conversion Lab to develop photobioreactors for the mass production of algae as a biodiesel feedstock. Designing and building a Photobioreactor (PBR) that produces oil at a competitive price requires precise delivery of sunlight and the photobiological formula to each algae cell in the system.
