超塑性成形和扩散焊接将用来制造F—15空中优势战斗机上用的七种发动机喷管的减阻装置。空军已在麦克唐纳·道格拉斯主办该项工作,以便确定用此种技术是否能更快更省地制造减阻装置。钛减阻装置将是按照空军材料试验室的约翰·威廉森所提出的超塑性成形法制作的最大部件。九磅的构件(每件大约为23×56时)将是单面波纹的复合外形板,金属板厚度在0.016至0.032时范围
Superplastic forming and diffusion welding will be used to make drag-reducing devices for seven engine nozzles used on the F-15 AirFighter. The Air Force has hosted the job at McDonnell Douglas to determine if drag reduction devices can be manufactured faster and more efficiently using this technology. The titanium drag reducer will be the largest part made according to the superplastic forming method proposed by John Williamson of the Air Materiel Laboratory. A nine-pound element (each approximately 23 x 56) will be a single corrugated composite profile with a sheet metal thickness ranging from 0.016 to 0.032
