钛精密铸造能缩短开发时间，降低生产成本．V－22OspreyTiltrotor型飞机传动接头中的多个锻造铝部件可用整体钛铸件代替．铸造加工带来了结构的灵活性，进而可取得优化的设计效果，更重要的是铸造可降低生产成本和部件数目．用整体钛铸件来作为直升机在疲劳工况下的主要结构，
Titanium precision casting can shorten the development time, reduce production costs. Multiple forged aluminum parts in V-22OspreyTiltrotor aircraft transmission joints can be replaced with integral titanium castings. Casting gives structural flexibility to optimize design results, and more importantly, casting to reduce manufacturing costs and parts count. With the overall titanium castings as a helicopter under fatigue conditions the main structure,
