GE Aviation在GenX商业航空公司发动机上获得3D印刷支架的FAA批准

GE添加剂andGE航空have announced that theFederal Aviation Administration(FAA)批准了要安装在Genx-2B commercial airline engines.

根据GE Aviation的说法,GenX是该公司历史上最快,最畅销的喷气发动机,其订单量超过1600。该发动机为这架四引擎波音747-8飞机提供动力,估计提高了15%的燃油效率,与GE的二氧化碳相比降低了15%CF6引擎

GenX-2B发动机上的原始PDOS支架是用坚固的金属和常规铣削块生产的,用于打开和关闭风扇围门。由于FAA的批准“设计变化”的结果,直接金属激光熔化(DMLM)将被实施,以加性制造支架,将材料废物减少90%。

A “groundbreaking success”

PDOS设计也得到了改进,以将支架的重量降低10%,并且将所有四个支架放在单个构建板上 - 在一个版本中生产一架飞机的括号。GE Aviation还决定使用从传统的基于镍的Superaly合金制成的钴粉合金来批量生产零件,以使其更快地构建。

This in-house process is expected to reduce its production costs, improve performance and utilization, and deliver a more fuel-efficient commercial aircraft engine.

“观看来自GE Aviation的团队,美国,墨西哥和德国合作的团队非常出色。在如此短的时间内,他们确实在PDOS括号中表现出色,并取得了真正的开创性成功。

“Seeing the M2 machines produce flight quality hardware, and demonstrating what it is truly capable of, is another great milestone in our own additive journey.”
