(2017-01-20消息)近日,国产最新型四代隐身战机重大改进型——鹘鹰2.0首飞成功。其中,沈阳航空航天大学所提供的增材制造钛合金承力构件在鹘鹰2.0首飞中发挥重大作用,这也标志着沈阳市增材制造技术水平比肩国内一流,迈入国内第一梯队水平。本次承担钛合金承力构件的部门是沈航航空制造工艺数字化国防重点学科实验室,是东北首家实现增材制造实现装机应用的单位。该实验室负责人介绍,承力构件是鹘鹰2.0飞机机体骨架的重要零部件,该实验室采用3D打印技术制造这种零部件,较传统的“锻铸+机械加工”制造方式比,可节省大型铸锻设备、减少开坯模具,大大缩短研制周期、减少制造成本,未来
(2017-01-20 Information) Recently, the latest domestic four generations of stealth fighters major improvements - Ying Ying 2.0 first flight success. Among them, the Shenyang University of Aeronautics and Astronautics provided by the addition of titanium alloy bearing components play a significant role in the first eagle Ying 2.0, which also marks the level of additive manufacturing technology in Shenyang, domestic first-class, into the domestic first echelon level . The commitment to bear the titanium alloy bearing components of the Ministry of Defense aviation manufacturing process digital key national defense laboratories, Northeast China is the first to achieve additional production units installed capacity applications. The person in charge of the lab introduced that the load-bearing component is an important part of the skeleton of the Ohawk 2.0 aircraft. The laboratory uses 3D printing technology to make such components. Compared with the traditional manufacturing method of “forging + machining” , Can save large castings and forging equipment, reduce billet die, greatly shorten the development cycle, reduce manufacturing costs, the future
