超塑成形是一项正在开发并应用于麦道公司T—45A型海军喷气式教练机机壳件定型的新技术。 T—45A型与其它不少飞机一样,其机身壳体和其他大型组件是采用铆接到一起的铝板件制造的。由于铆接劳动强度大,制造成本高,故超塑成形,作为一种终形状定型工艺,可大大降低制造成本和缩短装配时间。 美国海军部、美国国家金属加工技术专业研究中心(NCEMT)和麦道飞机制造公司携手合作,探寻可降低机头前锥、机头 Superplastic forming is a new technology being developed and applied to finalizing the shape of the McDonnell Douglas T-45A naval jet trainer chassis. Like many other aircraft, the T-45A is manufactured from riveted aluminum panels with its body shell and other large components. As the riveting labor-intensive, high manufacturing costs, so superplastic forming, as a final shape stereotypes process, can greatly reduce manufacturing costs and shorten the assembly time. The U.S. Department of the Navy, the National Metalworking Technology Research Center (NCEMT), and McDonnell Douglas Aircraft Manufacturing Company work together to find ways to reduce nose cone, nose
