SCUBAPRO Sunday – The Navy SeaBees

Sunday, September 5th, 2021

On September 1, 1942, the first Seabee unit to serve in a combat area, the Sixth Naval Construction Battalion (SeaBees), arrives on Guadalcanal.

I will not tell the story as there is a movie (with John Wayne, one of the seven he dies in), and I am posting a link at the bottom of an excellent article about them. I am going to say that Navy Seabees are some of the hardest working people you will ever find. I would rather have 1 Seabee than ten other people. They have built almost all the camps I have lived in since the first gulf war in Saudi Araba in 91 thru Iraq in the 2000s, and they never stop working on them to making them better. They build, they fight; you can ask them for something, and they will find it, they may be borrowing it, or they will make it. Indeed, some of the unsung heroes of the military.

Happy Birthday!

Turning Thermal Energy into Electricity Could Help Soldiers

Sunday, September 5th, 2021

RESEARCH TRIANGLE PARK, N.C. — With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging. Army-funded research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power for Soldiers on future battlefields.

Hot objects radiate light in the form of photons into their surroundings. The emitted photons can be captured by a photovoltaic cell and converted to useful electric energy. This approach to energy conversion is called far-field thermophotovoltaics, or FF-TPVs, and has been under development for many years; however, it suffers from low power density and therefore requires high operating temperatures of the emitter.

The research, conducted at the University of Michigan and published in Nature Communications, demonstrates a new approach, where the separation between the emitter and the photovoltaic cell is reduced to the nanoscale, enabling much greater power output than what is possible with FF-TPVs for the same emitter temperature.

This approach, which enables capture of energy that is otherwise trapped in the near-field of the emitter is called near-field thermophotovoltaics or NF-TPV and uses custom-built photovoltaic cells and emitter designs ideal for near-field operating conditions.

This technique exhibited a power density almost an order of magnitude higher than that for the best-reported near-field-TPV systems, while also operating at six-times higher efficiency, paving the way for future near-field-TPV applications, according to Dr. Edgar Meyhofer, professor of mechanical engineering, University of Michigan.

“The Army uses large amounts of power during deployments and battlefield operations and must be carried by the Soldier or a weight constrained system,” said Dr. Mike Waits, U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. “If successful, in the future near-field-TPVs could serve as more compact and higher efficiency power sources for Soldiers as these devices can function at lower operating temperatures than conventional TPVs.”

The efficiency of a TPV device is characterized by how much of the total energy transfer between the emitter and the photovoltaic cell is used to excite the electron-hole pairs in the photovoltaic cell. While increasing the temperature of the emitter increases the number of photons above the band-gap of the cell, the number of sub band-gap photons that can heat up the photovoltaic cell need to be minimized.

“This was achieved by fabricating thin-film TPV cells with ultra-flat surfaces, and with a metal back reflector,” said Dr. Stephen Forrest, professor of electrical and computer engineering, University of Michigan. “The photons above the band-gap of the cell are efficiently absorbed in the micron-thick semiconductor, while those below the band-gap are reflected back to the silicon emitter and recycled.”

The team grew thin-film indium gallium arsenide photovoltaic cells on thick semiconductor substrates, and then peeled off the very thin semiconductor active region of the cell and transferred it to a silicon substrate.

All these innovations in device design and experimental approach resulted in a novel near-field TPV system.

“The team has achieved a record ~5 kW/m2 power output, which is an order of magnitude larger than systems previously reported in the literature,” said Dr. Pramod Reddy, professor of mechanical engineering, University of Michigan.

Researchers also performed state-of-the-art theoretical calculations to estimate the performance of the photovoltaic cell at each temperature and gap size and showed good agreement between the experiments and computational predictions.

“This current demonstration meets theoretical predictions of radiative heat transfer at the nanoscale, and directly shows the potential for developing future near-field TPV devices for Army applications in power and energy, communication and sensors,” said Dr. Pani Varanasi, program manager, DEVCOM ARL that funded this work.

Marines 3D Print a Rocket Headcap for Mine-Clearing Missions

Saturday, September 4th, 2021

QUANTICO, VA —

The Marine Corps continues to leverage additive manufacturing to benefit the warfighter.

This summer, the Program Manager for Ammunition at Marine Corps Systems Command 3D printed a headcap for a rocket motor used to detonate a M58 Mine Clearing Line Charge. The MICLIC is a rocket-projected explosive line charge that provides a demining capability for Marines.

“The process of 3D printing allows Marines to create a physical object from a digital design,” said CWO2 Justin Trejo, a project officer with PM Ammo at MCSC. “We essentially created a 3D-printed product and incorporated it into a highly explosive system.”

Marines use the MICLIC to clear paths through minefields and other obstacles on the battlefield. However, traditional manufacturing methods for creating the headcap can be both timely and costly, said Trejo. MCSC wanted to identify a more efficient method for producing the part.

PM Ammo found the answer to this dilemma in additive manufacturing.

In 2019, PM Ammo began exploring alternative solutions for manufacturing the headcap. After many hours of research as well as developing and testing a prototype headcap, the team collaborated with Naval Surface Warfare Center Corona Division to produce a 3D-printed version.

Earlier this year, NSWC Corona produced the 3D-printed, stainless steel solution. The next month, PM Ammo representatives assessed the 3D product during a test event at Yuma Proving Ground in Yuma, Arizona. The evaluation involved launching the rocket motor to detonate the mine-clearing line charge.

Trejo said the event went flawlessly.

“The rocket motor fired off just as intended and the line charge detonated as it is supposed to, which was a significant moment for us.”

-CWO2 Justin Trejo, Project officer with PM Ammo at MCSC

“In the future, we’d like to attempt to 3D print the headcap with its nozzles attached,” said Trejo.

He stressed the significance of the successful test event because it further confirmed the effectiveness of 3D printing, which has been growing in popularity within the Department of Defense.

Additive manufacturing provides Marines with a streamlined solution to meet their needs. In 2019, MCSC established its Advanced Manufacturing Operations Cell to serve as a 24/7 help desk for Marines who need assistance with 3D printing, and other sustainment and manufacturing solutions.

AMOC is available to answer questions, field requests for prints and fully vet any part that requires fabrication by a Marine organization. The team of skilled Marines and civilians has employed additive manufacturing to develop everything from innovative maintenance tools to a reinforced concrete bridge.

Caleb Hughes, an engineer with MCSC’s PM Ammo who supported the Yuma testing event, said 3D printing saves the Marine Corps time and money.

“The previous process of traditional manufacturing is outdated, while 3D printing is a more modern manufacturing technique,” said Hughes. “I truly believe 3D printing is the next generation of the Marine Corps.”

Trejo believes additive manufacturing aligns with Commandant of the Marine Corps Gen. David Berger’s vision in that 3D printing helps increase Marines’ battlefield efficiency. Trejo said the manufacturing method enables the warfighter to be “lighter and faster,” critical attributes when supporting various missions.

“We’re able to create equipment parts and other assets for whatever particular mission we’re engaged in,” said Trejo. “This 3D-printed headcap represents the Marine Corps going above and beyond to support our Marines.”
