二、开发性工艺技术所谓“开发性工艺技术”,是指由于航空产品性能提高的需要而发展起来的工艺技术。其中包括通常所说的新材料工艺、新结构工艺和新技术工艺。为了实现航空工业产品现代化,我们应该大力开展开发性工艺技术的研究。现代高性能的飞机要求选用的材料、结构强度大,重量轻,疲劳寿命、断裂韧性好。从而发展了钛合金、复合材料、整体结构、蜂窝结构。如F15飞机钛合金用量占百分之二十六点二,复合材料用量占百分之二。复合材料的应用还处于初始阶段,今后随着技术上的成熟和成本的下降,在飞机上的用量会有大幅度的增长。这就必须在工艺技术上解决一系列问题,做大量的工艺研究工作。如钛合金整体结构的加工,钛合金板材的超塑成形、蠕变成形,电子束焊接,扩散连接等。复合材料结构则另有一
Second, the development of process technology The so-called “development process technology” refers to the development of aerospace products due to the performance needs of the technology developed. These include what is commonly referred to as new material technology, new structural technology and new technology processes. In order to modernize the aviation industry’s products, we should vigorously carry out research on developmental process technology. Modern high-performance aircraft require the use of selected materials, structural strength, light weight, fatigue life, good fracture toughness. To develop a titanium alloy, composite materials, the overall structure, honeycomb structure. Such as the F15 aircraft titanium alloy accounted for 26.2 percent, composite materials accounted for two percent. The application of composite materials is still in the initial stage, the future as the technology matures and the cost of decline in the amount of the aircraft there will be a substantial increase. This must be in the process of technology to solve a series of problems, do a lot of research work. Such as the overall structure of titanium processing, superplastic forming of titanium alloy sheet, creep forming, electron beam welding, diffusion bonding. The composite structure is another one
