这家法国航空航天公司已在伦敦的Helitech International推出了Aneto 1-K直升机发动机。Aneto Engine品牌以比利牛斯山脉的最高山的名字命名，具有3D印刷零件，并将被莱昂纳多（Leonardo）用来为其Agustawestland AW189K直升机提供动力。
该消息是在欧洲航空安全局（EASA）的批准之后的赛峰’s 3D printed metal turbine nozzle今年早些时候，列昂纳多的使用以前的AW189直升机。
3D打印必需组件
As part of its Tech 3000 innovation program, Safran has developed a number of internal 3D printed components. These include a “gyratory” combustion chamber with 3D-printed injectors made from heat resistant materials, a new inlet guide-vane system, and diffuser vanes with 3D-printed internal components.
With the introduction of additive manufacturing into the engine building process, Safran states that the Aneto will have a 25% power-to-weight ratio improvement over engines with a similar volume, and a 15% fall in operating costs. This is partly because the engine will necessitate fewer scheduled maintenance tasks and longer maintenance intervals.
Leonardo直升机董事总经理Gian Piero Cutillo表示：“我们很高兴AW189Kwill be the first helicopterto feature an Aneto engine。This new turboshaft engine will offer our customers a high level of performance and further extend the capabilities and versatility of our super medium platform, particularly in hot & high conditions.” Leonardo expects the helicopter AW189K to be certified for flight by late next year.

赛峰has previously formed an investment partnership with French 3D printer company Prodways, to打印飞机和防御组件。
制造商还进入了与澳大利亚的莫纳什大学合作to investigate 3D printed components. Rival turbo-machinery company Man Diesel & Turbo began 3D printing guide vanes今年早些时候。
