El Departamento de Defensa de EEUU desea avanzar r\u00e1pidamente en la utilizaci\u00f3n en gran escala, del revolucionario proceso tecnol\u00f3gico denominado \u201cFabricaci\u00f3n aditiva\u201d (AM-3DP), para su aplicaci\u00f3n espec\u00edfica en el dise\u00f1o y fabricaci\u00f3n de Sistemas de Armas Hipers\u00f3nicas (HW). Si bien en el 2023 est\u00e1 previsto disponer del primer Vector Hipers\u00f3nico en estado operacional, los expertos insisten en la necesidad de desarrollar e impulsar m\u00e1s r\u00e1pidamente, la incorporaci\u00f3n de capacidades de producci\u00f3n, que emplean masivamente AM. Ello permitir\u00e1 disponer de una Base Industrial para la Defensa, s\u00f3lida, flexible y en condiciones de satisfacer la demanda de grandes cantidades, de estos sistemas verdaderamente disruptivos. La experiencia de los recientes conflictos, muestra la necesidad de disponer de una r\u00e1pida respuesta del sistema industrial, para hacer frente a eventuales conflictos armados.<\/p>\n
WASHINGTON \u2014 The Pentagon wants to use an advanced technology process known as additive manufacturing to design and build hypersonic weapon and vehicle systems that can operate in extreme conditions.<\/p>\n
As the U.S. Department of Defense looks to field its\u00a0first hypersonic capability in fiscal 2023<\/a>, officials emphasize the need to shore up the industrial base and ensure programs can smoothly transition from development to production. Through an initiative called Growing Additive Manufacturing Maturity for Airbreathing Hypersonics, or GAMMA-H, it\u2019s targeting materials and processes used to build systems that travel and maneuver above Mach 5.<\/p>\n In a request for proposals issued Oct. 28, the department asked companies large and small, as well as academia, to submit prototype proposals for developing hypersonic components using additive manufacturing, which leverages computer-aided design software and often advanced materials to build components.<\/p>\n \u201cWe need to be pushing the envelope with materials produced using the additive manufacturing process,\u201d Kevin DeVries, deputy director of the Office of the Secretary of Defense\u2019s Manufacturing Technology Program, said in a statement. \u201cThe science has proven it\u2019s possible, but the practice is not widespread enough. GAMMA-H will encourage further adoption of groundbreaking technology.\u201d<\/p>\n Because the parts used to build hypersonic systems must operate under extreme conditions, they require advanced specifications and materials that can withstand high temperatures and other mechanical stress. The premise of GAMMA-H is that additive manufacturing techniques could help improve the quality of those parts and reduce the number of components needed to build a vehicle or weapon.<\/p>\n The Navy is leading the effort in partnership with the Manufacturing Technology program office. Proposals are due Dec. 12, and the department aims to move through the selection process quickly, though it gave no timeline.<\/p>\n
