Even after being frozen overnight at negative 35-degree temperatures in the severe winter conditions of Alaska, the elements of the Army’s second-generation tactical communications network backbone were up and running.

Warfighter Information Network-Tactical, or WIN-T, Increment 2, successfully completed its Cold Weather Natural Environments Testing in January at Fort Greely, Alaska, receiving positive test results in the execution and in its recently released test report from the Army’s Aberdeen Test Center. The data will be used to support a Full-Rate Production, or FRP, decision for WIN-T Increment 2, with a successful FRP decision providing the green light for the network’s fielding in Fiscal Year 2013.

“This was a very successful test and all of the equipment performed as we would have expected in extreme arctic conditions,” said Lt. Col. Robert Collins, product manager for WIN-T Increments 2 and 3. “Whether in the desert or in adverse cold environments, WIN-T Increment 2 will provide the needed on-the-move tactical network communications for maneuver elements on the battlefield all the way down the company level.”

The cold weather test sets the stage for WIN-T Increment 2′s formal operational test, which is the system’s final assessment prior to the full rate production decision.

Gas ‘Plume’ Detection System to Protect Soldiers, First Responders

The Local-Rapid Evaluation of Atmospheric Conditions uses both weather data and 3D terrain and building information to generate it's wind model. The model display how air flows around terrain and buildings so first responders can have a better idea how to approach or manage a site where an airborne hazard is present.

A wind monitoring and modeling system being developed by the Army Research Laboratory’s, or ARL, White Sands Missile Range, or WSMR, division could one day protect soldiers and civilians alike from weapons of mass destruction.

The Local-Rapid Evaluation of Atmospheric Conditions, or L-REAC, system is a computerized weather sensor system under development at ARL intended to help predict the flow of gasses and fumes, or “plumes,” produced by things such as gas leaks and chemical weapons.

Being able to identify how an airborne hazard will behave is a vital ability for first responders to have in order for them to know how to approach or evacuate an affected area.

“If you are a dispatch person and you have to direct first responders to the site, you can look at the wind field and see what the safest approach would be,” said Gail Vaucher, a research meteorologist with ARL at WSMR.

There are other systems available that can predict the plume with some accuracy. Such systems use things like wind speed, air pressure, temperature, and humidity in their calculations. But L-REAC system adds a new layer that previous systems didn’t have. Using terrain data, building plans and dimensions, L-REAC can model and display not only the plume, but the actual airflow around buildings and terrain features.

Researchers Unveil Robot Jellyfish Built on Nanotechnology



Researchers at The University of Texas at Dallas and Virginia Tech have created an undersea vehicle inspired by the common jellyfish that runs on renewable energy and could be used in ocean rescue and surveillance missions.

In a study published this week in Smart Materials and Structures, scientists created a robotic jellyfish, dubbed Robojelly, that feeds off hydrogen and oxygen gases found in water.

“We’ve created an underwater robot that doesn’t need batteries or electricity,” said Dr. Yonas Tadesse, assistant professor of mechanical engineering at UT Dallas and lead author of the study. “The only waste released as it travels is more water.”

Engineers and scientists have increasingly turned to nature for inspiration when creating new technologies. The simple yet powerful movement of the moon jellyfish made it an appealing animal to simulate.

The Robojelly consists of two bell-like structures made of silicone that fold like an umbrella. Connecting the umbrella are muscles that contract to move.

In this study, researchers upgraded the original, battery-powered Robojelly to be self-powered. They did that through a combination of high-tech materials, including artificial muscles that contract when heated.

The National Guard Association of Texas convened for the 53rd time to discuss the present and future state of the Texas National Guard as well as browse innovative new products and services on display at the Austin Contention Center, March 23 to 25.

Government contractors and private sector development firms rolled out their latest offerings in the hopes of sparking the interest of military commanders responsible for implementing policy and doctrine within the Texas Guard.

In light of proposed defense budget cuts, many presenters focused on budget conscious, adaptable, and enduring products that could be fielded by the Texas Military Forces. According to Rob Casias, the director of marketing and meetings for NGAT, “Only one tenth of one percent of the defense budget goes to the Guard.”

Mobility and efficiency were common themes on the convention floor. More than 100 vendors filled the convention center floor showcasing their latest innovation or service. “We try to select vendors with products that our Guard will be interested in,” Casias said.

Houston-based company Laser Shot had their digital marksmanship training and close quarters combat simulator available and invited attendees to their booth for a hands-on demonstration. Drawing inspiration from their roots in coin operated arcade shooters, the founders of Laser Shot developed a weapons training platform that they describe as “ultra portable and designed for training on the go.”

Brint Wood, a Laser Shot representative explained, “No matter what the skill set of the shooter we can challenge them.” Using accurately simulated weapons that a service member will carry in a deployed environment, video projectors and invisible lasers, the company created a budget-friendly system that fits inside a suitcase. Similar to arcade games, all the system needs to function is electricity, a surface to project an image on and minimal amounts of setup or training to run realistic training scenarios in a classroom environment.

“We save commanders time and money,” Wood said with a smile. Last month an M4 rifle simulator was returned to Laser Shot after firing 1.2 million rounds of laser ammunition. Wood said, “Multiply that by the cost of a 5.56 round and the system has already paid for itself.”

The Oshkosh Corporation also had their newest products and prototypes on display. Their new ProPulse Hybrid Electric Drive system, “meets or exceeds current or proposed emissions standards,” they said, utilizing a diesel-electric drive train. Oshkosh claims this setup will reduce emissions and improve fuel economy by 40 percent allowing for greater operational range without the logistical challenges associated with transporting large amounts of fuel allowing for more rations and equipment to be carried.

Secretary of Defense Leon Panetta said in a Department of Defense news release, “Smart use of energy can be a strategic advantage for the U.S. military against our adversaries. I want the department to harness the best energy innovations at all levels, from the individual warfighter to the largest installation, to enhance our operational effectiveness and deliver more bang for the buck.” Oshkosh is taking note of this philosophy and adapting its business for the future.

The U.S. Army will open its new complex, the Ground Systems Power and Energy Laboratory, during a grand opening ceremony at the Detroit Arsenal at 10 a.m., April 11, 2012.

The eight-labs-in-one Ground Systems Power and Energy Laboratory, or GSPEL, facility offers numerous testing capabilities and an unmatched combination of resources in a single lab. The GSPEL is part of the Army’s Tank Automotive Research, Development and Engineering Center’s, or TARDEC’s, laboratory system.

While closed to the public, the grand opening is expected to draw top government and industry leaders — many of whom are or will soon be GSPEL’s collaborative partners. GSPEL offers shared access to industry and academia to facilitate the exchange of information and ideas to develop emerging energy technologies and validate ground vehicle systems — research that could help the nation achieve energy security goals.

“GSPEL gives the Army overarching, full-spectrum testing and evaluation capability,” said TARDEC Interim Director Jennifer Hitchcock. “The GSPEL’s unique facilities will allow the Army to drive innovation for tomorrow’s energy solutions.”

TARDEC research scientists, engineers and technicians are already moving into the 30,000-square-foot facility. The eight individual labs are:

– Power and Energy Vehicle Environmental Lab, the centerpiece lab featuring one of the world’s largest environmental chambers for testing at temperatures from minus 60°F to 160°F, relative humidity levels from 0 to 95 percent, and winds up to 60 mph. The lab’s dynamometer and environmental chamber combination allows for full mission profile testing of every ground vehicle platform in the military inventory in any environmental condition.

– Air Filtration Lab is capable of testing the air flow characteristics of various-sized media at four different flow benches using varying flows up to 12,000 standard cubic feet per minute. Each flow stream is equipped with an automated dust feeder enabling simulations from zero visibility to four times zero visibility for evaluation of air filters, cleaners and other components.

– Calorimeter Lab is the world’s largest and is capable of testing radiators, charge air coolers, oil coolers individually or all three simultaneously.

– Thermal Management Lab tests thermally-managed mechanical and electrical components in varying environments. A variety of chiller and heat systems for use with test bench heat exchanges are used to evaluate components and systems.

– Power Lab evaluates major vehicle electrical systems including: charging systems, air conditioning systems, hydraulic systems and associated components. The lab’s two explosion-proof environmental chambers allow for expanded technical research.

– Fuel Cell lab tests future fuel cell capabilities for tactical vehicles. The lab enables the development and evaluation of fuel cell components and systems, including systems to reform JP-8 fuel, various fuel cell media and power conditioning, helping vehicles become quieter and more efficient.

– Hybrid Electric Components evaluate hybrid electric powertrains with the emphasis on developing hybrid motor technology and increased electrification of vehicles. Equipment used in this lab will potentially regenerate 80 percent power back into the building, making it possible to re-use the electricity.

– Energy Storage Lab makes it possible to safely test and evaluate advanced chemistry battery vehicle modules. Explosion-proof battery test chambers enable safe testing of 10-60 kW advanced chemistry battery packs.

Ground Renewable Expeditionary Energy Network – G.R.E.E.N. Marines



When you first think of military power, weapons strength may come to mind, but to the U.S. Marines they also think of alternative power. Army Staff Sergeant Daniel Symonds has the details.

Navy’s First Alternative Fueling Station Open in Hawaii

By Thomas Obungen, Naval Facilities Engineering Command Hawaii

Naval Facilities Engineering Command (NAVFAC) Hawaii officially opened the first of three Ethanol 85 (E85) fueling stations planned for the Navy’s fleet of flex-fuel vehicles March 22 at Joint Base Pearl Harbor-Hickam (JBPHH).

“The addition of this E85 fueling station to our fueling options directly addresses the energy mandates set forth by the Secretary of the Navy and the President,” said Capt. John Coronado, commanding officer, NAVFAC Hawaii. “We have over one thousand E85-capable vehicles at JBPHH that will be able to take full advantage of this station and the two others to be installed.”

Secretary of the Navy Ray Mabus has directed the Navy to reduce its consumption of petroleum by 50 percent before 2015, while the President’s Executive Order 13514 calls for a 28 percent reduction in green house gases, such as carbon dioxide, by 2020.

Flex-fuel vehicles commonly use E85, an alternative fuel of 85 percent plant-based ethanol blended with 15 percent gasoline that performs as efficient as unleaded gasoline would in regular vehicles. Ethanol is environmentally friendly, produces less carbon dioxide emissions, and helps reduce Hawaii’s dependence on foreign oil.

In September 2010, NAVFAC Engineering Service Center (ESC) awarded a $315,767 contract to the Honolulu office of Innovative Technical Solutions, Inc. (ITSI) to develop and construct a 10,000-gallon above ground fueling station adjacent to the existing government fueling station on Paul Hamilton Avenue, JBPHH. NAVFAC Hawaii assisted ESC in executing the project.

The contractor broke ground in April 2011 and completed all mechanical and electrical work July 15, 2011. Next, Space and Naval War Systems Command (SPAWAR) installed the Defense Logistics Agency (DLA) Fuel Master system, owners of the E85 fuel. After further adjustments, repairs, and final checks, the station became operational in March 2012. This means, all government gas cardholders and their government-owned flex-fueled vehicles are now expected to fill up with E85.

“Our E85 station may not have the amenities of some commercial fueling stations; but it will provide alternative fuel for personnel at JBPHH,” said Coronado. “All passenger carrying vehicles can pull in and fill up.”

The Navy’s E85 fueling station is the second of its kind in Hawaii to come online after one on Marine Corps Base Hawaii, Kaneohe opened in November 2010. Both are for government-use only. The Navy is currently evaluating other potential sites across the island.
