NSWCDD Biomedical Engineer Teams Up with High School STEM Champion to Mentor Students - 'Fun Twist on Math'
May 24, 2018
IMAGE: KING GEORGE, Va. - A local student explores the fact that all living organisms have DNA by extracting it from strawberries. He was among 14 students (and 12 parents) from Potomac Elementary School, King George Elementary School, and home schools participating in a Naval Surface Warfare Center Dahlgren Division (NSWCDD) sponsored science, technology, engineering and mathematics (STEM) event at the Dahlgren Heritage Museum, May 12. NSWCDD biomedical engineer Chelsey Lawson and Nathan Sullins, a high school junior STEM champion, mentored the second to sixth grade students who learned that strawberries have eight genome copies in every cell, making it easier to see the mass when it's extracted using dish detergent and isopropyl alcohol. "We take a fun twist on math by learning about statistics using starbursts," said Jon Dachos, HSI Surface Combat System Lead and STEM mentor who coordinated the event. "The students categorized and graphed the contents of their candy samples and we discussed other ways that statistics are useful. Finally, the students practiced principles of physics and civil engineering by building the tallest tower they could out of dry spaghetti and mini marshmallows. In order to engage students in different STEM careers, a poster is displayed that shows potential career paths based on their STEM interests."

The Economic and Intellectual Impact of Naval Surface Warfare Center Dahlgren Division
May 16, 2018
IMAGE: DAHLGREN, Va. (May 16, 2018) – The Naval Surface Warfare Center Dahlgren Division (NSWCDD) Economic and Intellectual Impact for fiscal year 2017 is outlined in the 'NSWCDD Impact' infographic released today by the NSWCDD Economic Impact Working Group. This year's study examined the organization’s influences on the local economy, state and county revenues, as well as academic and intellectual life and progress. Moreover, it analyzed how the command’s role as a Working Capital Fund Activity influences its operations, products, and services, and by extension – its customers, sponsors and the wider community.

Congressman Jody Hice Visits NSWC Dahlgren Division
April 27, 2018
IMAGE: DAHLGREN, Va. (April 24, 2018) - U.S. Rep. Jody Hice, (R-Ga.), shakes hand with Dale Sisson, Naval Surface Warfare Center Dahlgren Division (NSWCDD) deputy technical director, moments after Sisson presented Hice with the NSWCDD Centennial Coin in commemoration of the command's 100 years of research and development accomplishments. Throughout his tour of NSWCDD facilities, Hice saw the command's capability to develop and integrate complex warfare systems, including the ability to incorporate electric weapons technology into existing and future fighting forces and platforms. The official opening of business for Dahlgren began with the firing of the 7" Tractor Gun on October 16, 1918. Since June 1918, when President Woodrow Wilson signed a proclamation to acquire nearly one thousand acres to create the original ordnance proving ground during World War I, through today, Dahlgren has served as the center for the scientific research and development that led to hundreds of patents, innovations, and scientific breakthroughs for the U.S. Navy. Each week, NSWCDD posts new content for the public to learn more about the many people, places, and amazing projects that the command and this base has produced over the last century: http://www.navsea.navy.mil/Home/Warfare-Centers/NSWC-Dahlgren/Dahlgren_Centennial/.

Navy Engineer on Cutting Edge of Vibration Technology Wins Navy Technical Excellence Award
March 20, 2018
IMAGE: DAHLGREN, Va. - Naval Surface Warfare Center Dahlgren Division (NSWCDD) engineer Shawn Schneider mounts an adapter plate to an Unholtz-Dickie T-2000 electro-dynamic vibration system capable of providing over 24,000 pounds of force in vibration at frequencies up to and exceeding 3,000 hertz (cycles per second). These systems are used to replicate shock and vibration environments experienced by test items during their lifecycle to ensure that performance and safety are not compromised prior to use by the warfighter. NSWCDD announced on March 20 that Schneider won the 2018 Department of the Navy Award for Technical Excellence at a Test and Evaluation Facility or Range. The engineer was honored for extraordinary scientific and engineering contributions to the test and evaluation community in the area of multi-input-multi-output vibration test profiles.
Japan Maritime Self-Defense Force Tours NSWC Dahlgren

IMAGE: DAHLGREN, Va. (Feb. 16, 2018) - Japanese Vice Adm. Hideki Yuasa and Capt. Takuro Koroki are pictured with their delegation and Naval Surface Warfare Center Dahlgren Division (NSWCDD) leadership in front of the electromagnetic railgun prototype launcher. Yuasa is president of the Japan Maritime Self-Defense Force (JMSDF) Maritime Command and Staff College in Tokyo and Koroki is the naval attaché for the Embassy of Japan and the JMSDF delegation. Yuasa led the Japanese delegation to see new and emerging technologies developed at NSWCDD. Navy scientists and engineers briefed the Japanese delegation on human systems integration, electromagnetic launchers, hypervelocity projectiles, and directed energy weapons, in addition to the command's capabilities in complex warfare systems development and integration to incorporate electric weapons technology into existing and future fighting forces and platforms.

University of Virginia and NSWC Dahlgren Partnership Impacts 3D Printing Research
March 12, 2018
IMAGE: CHARLOTTESVILLE, Va. - University of Virginia students investigate material properties with a microscope. The students and their professors teamed up with Naval Surface Warfare Center Dahlgren Division (NSWCDD) engineers and scientists through the Naval Engineering Education Consortium (NEEC) to develop a better understanding of the capabilities and limitations of additive manufacturing (3D printing). "The research that the University of Virginia is conducting is an important examination of the microstructure and mechanical properties of alloys relevant to the Navy produced by state of the art additive manufacturing techniques," said Ricky Moore, an NSWCDD engineer and mentor to the students. "Understanding these properties is paramount as the Navy begins to design, develop, produce, and field components and systems produced with additive manufacturing to improve performance and availability of systems in the Fleet. Without it, much of the promise of additive manufacturing will be out of reach."
Local Students and NSWC Dahlgren Mentor Make STEM Connection - Demonstrate Effects of Liquid Nitrogen
March 2, 2018
IMAGE: FREDERICKSBURG, Va. - Navy engineer Josh Taylor conducts a liquid nitrogen demonstration with students at the science, technology, engineering and mathematics (STEM) Summit hosted by the Fredericksburg Academy, Feb. 24. Taylor - a Naval Surface Warfare Center Dahlgren Division (NSWCDD) STEM mentor - and the students discussed the Ideal Gas Law, and how it relates different attributes of a fluid. In the picture, they are exposing the inflated balloons to liquid nitrogen and observing that the volume of air inside the balloons decreased as the temperature decreased. Taylor and the students then discussed and demonstrated how changes in temperature could be used to produce kinetic energy, and how temperature changes could affect the behavior of materials. For example, they made flowers shatter like glass, tennis balls that would not bounce, and rubber bands that cracked. "I really enjoyed talking to students and answering their questions, not just about basic principles, but introducing concepts that one doesn't normally explore until college," said Taylor. "I think Dahlgren mentors play a crucial part at venues like this because we help students make a connection between ideas they learn in school and real work they could do one day. Personally, I've met many students who were inspired by events like this to engage the sciences and applied sciences not just as homework - but as a vocation."
