近日,全球著名飞机制造商德事航空(Textron Aviation)推出了一款新型的入门级商务客机Cessna Denali。它的亮点很多,比如拥有同类机型中最大的机舱(最多可搭载8人),非常舒适,以及售价仅为480万美元等。不过这其中,最有特色的还是它安装的螺旋桨发动机,因为它是由该公司与通用航空(GE Aviation)采用3D打印技术联合开发的。

德事隆航空采用3D打印飞机引擎:油耗降低20%

据了解,两家公司之所以选择使用3D打印技术来开发这款发动机主要是因为它采用了全新的设计,将原先数以百计的零部件大幅减少了,而新零部件的几何形状都相当复杂,很难通过传统工艺制造。最终,这些新部件是采用钛与不锈钢3D打印而成的,而由此带来的好处就是与原来相比,发动机的油耗降低了20%,但功率却提高了10%,同时大修的时间间隔提高了至少30%。因此,通用航空的董事长兼CEO Jeff Immelt甚至表示,这款新型发动机有望在25年内为他们带来400亿美元的受益。

另外,这款发动机还有两个亮点,第一就是虽然是螺旋桨式的,却采用了喷气发动机的技术。这种设计提高了压气机和涡轮的内部温度与压力,令发动机得到了1650轴马力的高输出功率;第二就是将包括3D打印部件、气冷涡轮叶片,以及发动机和螺旋桨的管理集成到了一个综合推进控制系统中――这可有效降低飞行员的工作负荷。

目前,德事隆公司和GE航空已经在威斯康辛州Oshkosh的EAA AirVentures航空展上正式展出了这款新型客机。不过由于需要进行为期至少1年的测试,所以它的首飞将会延期到2018年。
