Rowan University Project Will Develop Composite Materials Used to Protect Soldiers

By Kimberly Hoodin

Rowan University will lead a $14.5 million Department of Defense/Army Research Lab project to create new composite materials – and ways to process those materials – that will help modernize the Army and improve the safety of soldiers in the field.

The project, titled “Advancing Structural Materials for Army Modernization Priorities via Direct-Write Approaches,” will be led by researchers from Rowan University teamed with PPG, Drexel University, Northeastern University and the University of Massachusetts Amherst to create new advanced composite and plastic materials and ways to process them. The project is driven by a cooperative agreement with the U.S. Army Combat Capabilities Development Command Army Research Laboratory.

The team will work on developing innovative materials by using “cold-spray” advanced manufacturing technologies. The work will focus on polymers, starting with polystyrene, then move on to more advanced composite materials and systems, as designated by the Army.

“The high particle velocity of cold spray enables rapid cure and adhesion of polymers. This should result in the fast and efficient production of high-performance composite parts or repair of parts,” said John La Scala, associate chief the ARL's Materials and Manufacturing Sciences Division and cooperative agreement manager for the research program. “Additionally, this novel manufacturing methodology is a layer-by-layer production of composites, which should reduce void and flaw content. This should improve strength and durability significantly, thereby opening the potential of using this manufacturing technique to prepare composites for extreme conditions, while replacing the current expensive manufacturing methods with a much more economical methodology.”

Researchers hope to develop materials to be used for making military equipment stronger and lighter, soldiers more agile and vehicles more durable. Longer-term, the team sees the potential for use of the materials in the fields of civil aviation, automotive, health care and space exploration.

“We will work to make materials more quickly, to make them better and easier to repair offsite and, importantly, onsite in the field,” Dr. Joe Stanzione, associate professor of chemical engineering at Rowan University said. “That includes everything from parts for tanks and jeeps, to usable tools, and helmets.”

Army to hold competition to build ventilators for COVID-19 emergency response
By: Jen Judson WASHINGTON — The Army's acquisition chief, Bruce Jette, has directed the Army's Expeditionary Technology Search program to hold a competition for solutions to rapidly build ventilators to support the COVID-19 virus emergency response, according to an April 9 service statement. Addressing the United States' ventilator shortage needed to treat severe cases of COVID-19, the xTechSearch team will tap industry for innovative approaches to building an inexpensive, emergency ventilator “that requires minimal components and is designed for simplified mass production,” the statement reads. The competition will be open to “any American business, regardless of size,” the statement notes. The team will begin accepting virtual pitches from competitors starting April 13. “Novel solutions” will win a prize of $5,000 to present pitches of the concepts virtually to a panel of judges, according to the statement. The Army will then award $100,000 cash prizes to winning solutions to develop concept prototypes, it adds. Some technologies could receive follow-on contracts for further production and deployment. "The technology solution must provide a rapid-response breathing apparatus capable of short-term, rugged field operation in a small footprint that will support field hospitals," Zeke Topolosky, the Army xTechSearch program manager, said in the statement. The statement did not detail how rapidly technologies should move from concept to prototype to production. xTechSearch is a competition sponsored by the Army's acquisition branch “targeting small businesses to uncover novel dual-use science and technology solutions,” according to the program's website. “The competition aims to tackle the Army's most critical modernization challenges supporting the top Army focus areas.” https://www.defensenews.com/land/2020/04/09/army-to-hold-competition-to-build-ventilators-for-covid-19-emergency-response/

The Air Force may have found new imagery it needs at a pitch day
By: Nathan Strout The Air Force awarded Capella Space a $750,000 base contract for high-resolution radar imagery during one of the service's rapid acquisition events earlier this month. Capella Space announced Nov. 20 that the Air Force plans to use the company's sub 0.5 meter synthetic aperture radar imagery for virtual reality software, missile defense and developing predictive intelligence to foresee foreign threats. “The U.S. Air Force is always working to maintain our leadership as a global technology innovator, and this contract is a testament to that commitment,” said Lt. Gen. John Thompson, head of the Air Force's Space and Missile Systems Center. SAR satellites are unique in their ability to collect imagery despite adverse weather or lighting conditions that make optical sensors useless. Unlike optical sensors, SAR sensors can pick up data on material properties, moisture content, elevation and precise changes and movements. In addition, SAR data can be used to make both 3D recreations or 2D images of 3D objects. Capella plans to launch its first SAR satellite in early 2020 as part of a constellation of 36 satellites that it expects to be operational in 2022. “Capella will work alongside the U.S. Air Force to foster collaboration and deliver a product that best suits their mission needs,” Dan Brophy, vice president of government services at Capella Space, said in a statement. “Timely SAR data that presents changes on Earth holds tremendous military value, and we will make adaptations to meet unique military requirements. Together with the Air Force, we will define the applications for this data in its hybrid, military and commercial space architecture.” The contract was awarded during the Air Force's Space Pitch Days Nov. 5-6, where the Air Force invited small and nontraditional companies to make pitches for their products and solutions in an environment like the television show “Shark Tank.” The Air Force awarded Phase II Small Business Innovative Research contracts on the spot to several companies, including to Capella Space. At the conclusion of this base contract, Capella could win a Phase III contract in 2020. https://www.c4isrnet.com/intel-geoint/2019/11/25/the-air-force-may-have-found-new-imagery-it-needs-at-a-pitch-day/

Bell Invictus to Offer Army ‘Lower-Risk Path’ to FARA Capabilities
By Brian Garrett-Glaser ARLINGTON, Texas — Bell's offering for the Army's Future Attack Reconnaissance Aircraft (FARA) contest, the 360 Invictus, is intended to offer the Army an insurance policy by presenting a lower-risk path to the capabilities it hopes to acquire as a “knife fighter” light attack helicopter to replace the retired OH-58 Kiowa Warriors. The Invictus, with its low-drag tandem cockpit design, draws from a lot of the development Bell has put into the 525 Relentless, a super-medium utility aircraft it hopes will be the first fly-by-wire rotorcraft certified for the civil market. Though Bell's FARA program is newer than some of its competitors, such as Sikorsky's S-97 Raider — Bell officials said the program had just three employees at this time last year and now comprises over 200 — the company believes its reliance on systems which it already has at a high technology readiness level due to work on the 525 will provide the Army with a compelling aircraft inside of its cost and timeline objectives. “It's still a very advanced aircraft. But by using technologies that we already had high TRLs in, or high manufacturing readiness levels in, we are ahead on that timeline piece,” Frank Lazzara, director of advanced vertical lift systems, told Avionics International during a press visit to the company's Flight Research Center here. The Invictus design meets or exceeds Army requirements in every area, according to Lazzara, due in part to the clean-sheet engineering that went into the Bell 525, including in the main and tail rotor systems. That aircraft has flown in excess of 200 knots without issue, despite being designed for 160 knots cruise speed. Bell intends the Invictus to cruise efficiently at 180 knots. “We flew [the 525] until we said we're done, but that rotor wasn't done,” said Josh O'Neill, senior manager for technology and evaluation on the Bell 525 program. “So we went not just 201 knots. It was a good bit more than that.” The 525 Relentless was the first aircraft Bell designed “totally in the 3D space,” O'Neill said, and the Invictus is similarly using a digital thread, enabling things like virtual reality maintaining exercises to provide design feedback without a physical product. “You have a digital thread, the same part that's used when you design your aircraft is used in the maintenance training, used throughout the product,” said O'Neill. “You design the aircraft in 3D, lay out all the systems and you're able to go in there with an actual maintainer. So we pulled [a line maintainer] and had him put the gloves on and go maintain the aircraft. And you can see in the 3D space, I need to reach around this piece, I need to turn my hand in a way that the human hand doesn't like to be turned. So we need to move that item.” As a fly-by-wire aircraft designed with a modular open systems architecture (MOSA) approach, Bell believes Invictus will provide the Army with an path to autonomy — or enable a single person in the aircraft to focus on mission functionality — similar to Bell's approach with the V-280 Valor, its offering for the Future Long-Range Assault Aircraft (FLRAA) competition. Bell officials said they are currently introducing autonomous flight software and performing software regression tests for that aircraft and intend to begin autonomous flight tests within the next few months. In March 2020, when the Army narrows the FARA competition from five companies to two, Bell's team will be nine months into design. After that, two of the five designs — selected from Sikorsky, Bell, Karem Aircraft, AVX/L3Harris, and Boeing — will be selected to participate in a fly-off slated for the second half of 2022. The Army hopes to field the first FARA aircraft in 2028. https://www.aviationtoday.com/2019/12/15/bell-invictus-offer-army-lower-risk-path-fara-capabilities/
