3D打印在航空制造中的应用
1、打印涡轮叶片铸造型芯
在铸造金属涡轮叶片时,为了形成高度复杂的内部冷却通道结构,常使用陶瓷铸造型芯。铸造叶片冷却后,将叶片从模具中取出,同时内部的陶瓷型芯需要溶解掉。
目前,陶瓷铸造型芯的结构越来越复杂,通过传统的注射成型方式已经无法实现。奥地利Lithoz公司采用LCM技术制造陶瓷叶片型芯,可以满足航空航天和电力工业的需求。
LithaCore 450是由Lithoz公司自主研发用于3D打印陶瓷叶片型芯的硅基材料,制备精度高,烧结后的叶片型芯产品具有非常低的热膨胀率、较高的孔隙率、优异的表面质量和优良的洗滤性等优点。典型的应用有:单晶镍基合金涡轮叶片铸造型芯、定向凝固铸造型芯、等轴铸造型芯。
2、打印发动机支架
2018年11月1日,GE增材制造宣布,美国联邦航空管理局已批准3D打印支架用于波音747-8 机型的GEnx-2B发动机(双转子轴流式大涵道涡轮风扇发动机),该支架将取代传统制造的电动门打开系统支架,其作用是打开和关闭发动机的风扇罩门,制造设备为GEAdditive Concept Laser M2多激光器选区激光熔融系统。



这款3D打印支架将在GE航空集团阿拉巴马州奥本市的工厂开始批量生产。GE公司表示,与传统方式制造的支架相比,3D打印技术将减少高达90%的材料浪费。在传统支架的制造中,因金属加工而产生的材料浪费约占50%。此外,3D打印支架采用了优化设计方案,重量比传统支架轻10%。


据了解,这款3D打印支架为GE航空创造了两个“第一”。首先,这是GE 第一个获得认证的由ConceptLaser公司的选区激光熔融设备生产的3D打印零件。其次,这是GE航空第一次完成一种3D打印零件从设计到生产于10个月内开发完成。
在进行支架生产时,一次打印可以生产4个支架,在构建室中4个支架以互锁设计的形式实现,打印材料为钴铬合金。
3D打印支架的制造成本低于原有成本,GEnx发动机的订单量为2200台,整体来看节约的成本非常可观,并且3D打印支架比传统支架更轻,将为航空公司节省燃料。
3、打印燃料喷嘴
2010年,空客将GE生产的LEAP-1A发动机作为A320neo飞机的选配,LEAP发动机中就带有3D打印的燃油喷嘴。2015年5月19日,A320neo飞机首飞成功,装有LEAP发动机的A320neo 同时获得欧洲航空安全局和美国联邦航空管理局的认证。
2018年10月8日,GE航空工厂庆祝第30000个3D打印燃料喷嘴的成功出货。该喷嘴自2018年以来一直在该工厂生产,标志着规模化增材制造的重要里程碑,预计2019年这种产品将达到40000支。
