The French aerospace company has launched its Aneto 1-k helicopter engine at the Helitech international in London. The Aneto engine brand, which takes its name from the highest mountain in the Pyrenees, features 3D printed parts and will be used by Leonardo to power its AgustaWestland AW189K helicopter.
The news follows the European Aerospace Safety Agency’s (EASA) approval ofSafran的3D印刷金属涡轮喷嘴earlier this year, which was used in Leonardo’sprevious AW189 helicopter。
3D printing essential components
作为其技术3000创新计划的一部分，Safran开发了许多内部3D打印组件。其中包括一个“旋转”燃烧室，该燃烧室具有由耐热材料制成的3D打印喷油器，新的入口导管系统以及带有3D打印内部组件的扩散叶片。
随着添加剂制造的引入发动机制造工艺，Safran指出，与具有相似量的发动机相比，Aneto将有25％的功率与权重率提高，并且运营成本下降了15％。这部分是因为引擎将需要更少的计划维护任务和更长的维护间隔。
Gian Piero Cutillo, managing director at Leonardo Helicopters stated, “we are pleased that theAW189K将是第一架直升机配备Aneto引擎。这款新的TurboShaft发动机将为我们的客户提供高度的性能，并进一步扩展我们超级中型平台的功能和多功能性，尤其是在炎热和高条件下。”莱昂纳多（Leonardo）预计直升机AW189K将于明年年底获得飞行认证。
每分钟3D打印革命
Safran以前曾与法国3D打印机公司Prodways建立了投资合作伙伴关系，print aircraft and defence components。
The manufacturer has also entered apartnership with Australia’s Monash university调查3D打印组件。竞争对手涡轮机械公司的男子柴油和涡轮增压工程3D打印导板earlier this year。
