Researchers at the U.S. Naval Research Laboratory Electronics Science and Technology Division are working to help the U.S. Marine Corps (USMC) reduce expeditionary energy supply needs and risks and increase the effectiveness of forward deployed forces.

“One of the most significant challenges currently facing the Marine Corps is the need to supply sufficient electricity to individual Marines in forward operating bases,” said Robert Walters, head, NRL Solid State Devices Branch. “Mobile photovoltaics are a technology that can address these needs by leveraging emerging, flexible, high efficiency photovoltaic technology.”

The military’s need to reduce both fuel and battery resupply is a real time requirement for increasing combat effectiveness and decreasing vulnerability.  The overarching objective of the USMC Expeditionary Energy Strategy is to increase operational energy efficiency on the battlefield through the combination of on-installation alternative energy production and energy demand reduction.

This subsequently is projected to reduce fuel consumed, per Marine, per day, by 50 percent and reduce total weight of batteries carried by nearly 200 thousand pounds.

Hydrogen Fuel Cells – Energy Made Easier

Video provided by the Naval Research Laboratory

Sustainable energy seems to be the topic of conversation these days.  The Office of Naval Research and the Naval Research Laboratory are testing zero-emission hydrogen fuel cells. That means vehicles can operate without emitting waste products that pollute the environment or disrupt the climate.

In this video, Dr. Karen Swider-Lyons, a Material Science Engineer at NRL, and other subject matter experts explain how hydrogen fuel cells work and why they are important to the U.S. Navy.  Check out the NRL Chemistry Division, or for more NRL videos, click here.



Stop, Hey, What’s That Sound?

The deafening roar of supersonic aircraft can cause hearing damage to sailors and Marines on flight decks, so the Office of Naval Research (ONR) is funding a new project to help reduce jet noise.

“The noise problem falls into two categories: noise exposure on the flight deck and noise impact on the communities surrounding air bases,” said Dr. Brenda Henderson, deputy manager for the Jet Noise Reduction project, part of ONR’s Noise-Induced Hearing Loss (NIHL) program. “We’re funding the development of tools that we’ll need to help control jet noise in tactical aircraft.”

Hearing loss is not uncommon for service members, so combating this problem could mean more than keeping the jets at a comfortable indoor-voice level.

An Engine Of Ice and Fire

Preps Continue for Launching Engine Icing Research

NASA scientists are making progress in their preparations to mount a detailed research campaign aimed at solving a modern-day aviation mystery involving the unlikely combination of fire and ice inside a running jet engine.

The investigation deals with the seemingly strange notion that ice crystals associated with warm-weather storms can be ingested into the core of a jet engine, melt and then re-freeze, potentially causing the engine to lose power or shut down altogether. Safety officials have documented more than 150 incidents of this phenomenon since 1988. Most of the incidents have occurred in the tropics.

“It doesn’t seem intuitive that ice can form in the core of a warm engine,” said Ron Colantonio, manager of the Atmospheric Environment Safety Technologies Project at NASA’s Glenn Research Center in Cleveland.

So in order to make sense of the mystery, NASA and its research partners are planning to gather information by flying a specially-outfitted business jet in high-altitude, warm-weather conditions suspected of having a large amount of ice crystals.

Technicians in California are currently modifying a Gulfstream G2 airplane to hold a suite of meteorological instruments, with hopes of having everything ready for initial trial runs of the full setup in Florida this August.

The research team then will take the lessons learned from their trial runs, make appropriate changes and prepare for the primary campaign, which is now targeted between January and March, 2013. These flights will take place over Darwin, Australia, an area known for having the type of storms that include high levels of ice crystals.

Keeping Cool: Cryogenics And The Military

Story written by Airman 1st Class Zachary Perras 

U.S. Air Force Staff Sgt. Dustin Volpi, 354th Logistics Readiness Squadron fuels distribution supervisor, issues liquid nitrogen to a liquid nitrogen cart. Liquid nitrogen can temporarily shrink mechanical components during machine assembly to perform press fits - the process of fastening two parts by friction. (Photo by Staff Sgt. Jim Araos)

The word “cryogenic” is derived from the Greek words kruos, for frost, and genos, for origin of creation. In essence, cryogenics is the technology and art behind producing low temperatures. Here at Eielson, that art is imperative to the flying mission.

As the dedicated cryogenics expert at Eielson, Staff Sgt. Dustin Volpi knows how the process should function, how to handle and manage liquid nitrogen and oxygen and how to maintain operational readiness for Eielson’s fliers.

“We keep the mission going,” said Volpi, 354th Logistics Readiness Squadron fuels distribution superviser. “Without us, the planes don’t fly. That’s what we do.”

In cryogenics, there is liquid oxygen, primarily used as aviator breathing oxygen, and liquid nitrogen, used to service the emergency power unit, the emergency source of electrical and hydraulic power in the event the onboard generators or engine fails on the F-16 Fighting Falcon. Cryogenics is a heavily inclusive part of the flying mission because of this, Volpi said.

However, cryogenics here is quite different from any other base. When temperatures drop to 50 below zero, limitations arise, affecting the capabilities and how quickly a task can be finished. On top of this, frostbite can easily occur. Since liquid nitrogen boils at minus 321 degrees Fahrenheit and liquid oxygen boils at minus 297 degrees Fahrenheit, the potential for danger rises.

“You can only stay out there for so long because it’s so cold,” Volpi said. “It’s even colder standing by the equipment because the cryogenics are so cold. If you add the environment from the gases boiling off, it gets cold really quick.”

Beyond Waste

From www.launch.org

The goal of the LAUNCH: Beyond Waste Challenge is to identify ten “game changing” innovations that have the potential to transform the current waste management systems and practices to ones focused on minimizing waste and/or transforming waste into new products.

LAUNCH invites proposals for innovative design for zero waste solutions, waste elimination, waste transformation, and waste mitigation technologies, as well as waste reduction-focused education, business, and financial strategies that have the potential to reduce and/or eliminate waste at a household, community, office building, campus, or industrial level.

The Waste Hierarchy establishes a ranking of management options in context of increasing environmental impact, and is based on the simple premise that it is better to avoid generating waste than to treat or dispose of waste.

The ultimate goal of LAUNCH is a sustainable future for planet Earth and its inhabitants. The LAUNCH: Beyond Waste Challenge seeks to identify entrepreneurial efforts focused on the development of innovative products, services, and programs that can benefit from collaborating and networking with influential government and business leaders to accelerate their deployment and adoption in both the developed and developing worlds.

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.
