China3D printingNet, October 29, the US Navy Department recently announced a strategic plan for the period 2021 to 2025, which prioritizes the development of hypersonic weapons, with a view to making Dahlgren a leader in the integration of hypersonic weapon systems in the surface navy. . The ultimate goal of this “hypersonic technology thrust” is to develop a continuous defense team dedicated to hypersonic technology.
As part of this program, Dahlgren has established a number of partnerships with other Department of Defense (DoD) agencies, industry partners, and academic experts through the Naval Surface Technology and Innovation Alliance and the Naval Engineering Education Alliance. This includes the Extreme Materials Institute at Johns Hopkins University and the 3D Printing Center at the University of Miami.
Adam Jones, head of the Advanced Hypersonic and Guided Munitions Department of NSWCDD, said: “We are at work every day looking for ways to put new capabilities into the hands of our combatants.” “Offensive and defensive hypersonic weapons will provide our navy with the necessary In order to maintain the naval superiority over our opponents.”

Supersonic: blink, you might miss it
Hypersonic flight is defined as a speed of at least Mach 5, which is five times the speed of sound or approximately 6,800 miles per hour. With today’s aviation technology, it takes about 5 hours to fly from Los Angeles to New York, but at Mach 5, it only takes 40 minutes. When used in the field of national defense, the technology can be used for hypersonic missiles, a high-speed warhead carrier that is more difficult to intercept by air defense systems.
Are you right nowHypersonicdeep impression? The same is true for the Ministry of Defense. In 2020, the United States will list hypersonic weapons and anti-hypersonic systems as its top technological modernization priorities, which means that once they are ready, they will become very useful tools.
Dahlgren is at the forefront
NSWCDD is ideally suited to lead the advancement of hypersonic technology in the United States because it has an extensive history of supporting similar projects. After World War II, Dahlgren oversaw a feasibility study on the defense of supersonic aircraft and missiles with hypervelocity guns, which was futuristic at the time. In the decades since, NSWCDD has also developed software for launching naval submarine-based high-speed ballistic missiles and designed a ramjet capable of flying at Mach 4.
“NSWCDD has more than 60 years of expertise in developing, testing, and evaluating advanced materials for systems operating in extreme heat and ablative environments, just like in the case of hypersonic and reentry aircraft-this is our DNA, “Dr. Pearl Rayms added-Keller, Chief Scientist of the NSWCDD Strategy and Computing Systems Department.
Recently, the department received more than $4 million in internal investment to fund 22 Naval Innovation Science Engineering (NISE) hypersonic projects, including the development of new hypersonic materials and advanced hypersonic simulations. In cooperation with the University of Miami’s 3D Printing Center, the department’s research team can now use additive manufacturing systems, which means they will be able to take advantage of improved cycle time, design flexibility, and tool-free production to accelerate hypersonic development work.
NSWCDD also participated in the testing of hypersonic railgun weapons. The photo is from the U.S. Navy.
This is certainly not the first time that the Department of Defense has applied additive manufacturing to hypersonic research, because the Pentagon recently awarded 18 university-led hypersonic projects with a total of $25.5 million. One of the projects led by the University of Virginia aims to 3D print high-temperature parts made from previously unused niobium alloys. It is hoped that these proposed 3D printing functions will eventually be applied to hypersonic supersonic ramjet engines.
ASTRO America, an applied science and technology research organization, has also previously completed a study commissioned by the US DARPA to accelerate the production of hypersonic missiles using 3D printing. The study details the design plan for the Hypersonic Production Accelerator Facility (HPAF), which integrates every level of government customers and leading manufacturers under one roof.
