One of the world's most costly fighter jets now can boast a 3D-printed part: a titanium bracket installed last month on an F-22 Raptor during maintenance in Utah. The experiment holds promise for the small F-22 fleet because 3D printing would allow parts production as needed.
Additive manufacturing is slowly making headway in the US military with the Navy's approval of a 3D-printed metal drain strainer for a steam line for aircraft carrier USS Harry S. Truman. But approvals only come after years of study, and the strainer is being installed on a test basis for one year.
Researchers have found a way to eliminate toxic carbon dioxide and create electricity and hydrogen by creating a sodium-carbon dioxide system that melts CO2 in water. As the aqueous solution becomes more acidic, it adds protons to attract electrons.
ASME Learning & Development is holding a MasterClass Series event on Pressure Technology from March 11-15 in Las Vegas. The courses are intended for pressure tech engineers and technical professionals working for owner-users, manufacturers or engineering and design construction firms in the refining, petrochemical and other comparable industries. To see the full list of courses and to register, visit GO.ASME.ORG/LASVEGAS8.
Cancer patients sometimes neglect to take the pills they need to fight their disease, but University of Minnesota researchers have developed a way to remind them and keep track of timing and dosages. Sensors embedded in each pill signal wearable receiver patches that, in turn, relay the information to the patient's smartphone and the physician's medical records.
Florida Polytechnic University used a $46,000 NATO grant to buy a 3D printer that can produce continuous carbon fiber-reinforced polymer shells that can withstand the intense pressure of nuclear radiation detectors. The high-strength material will allow researchers to improve the efficiency and portability of ionization detectors, says grant winner Robert Austin, a physics professor.
The USS North Dakota is winding up a six-month deployment -- its first -- and is due to return to its Groton, Conn., home port at the end of this month. The sub is the second US naval vessel named after the state.
The Navy's littoral combat ships were out of action last year, but that will change this year. Vice Adm. Richard Brown, commander of Naval Surface Forces, says the USS Montgomery and USS Gabrielle Giffords will deploy from San Diego to the Western Pacific, and the USS Detroit will deploy to the East Coast from Mayport, Fla.
The Navy says it successfully test-fired near-hypersonic projectiles from existing guns on a destroyer last summer. The tests were carried out as part of the Rim of the Pacific exercises aboard the USS Dewey using its standard Mk 45 5-inch main deck gun.
General Dynamics will be planning and carrying out
maintenance and upgrades on the USS George H.W. Bush under a new $91.4 million contract. Work includes dry-docking and depot-level maintenance and various modifications.
