       Naval Group和Centrale Nantes已经使用增材制造印刷了第一个用于军事应用的全尺寸螺旋桨叶片演示器。在2016年启动的海洋技术联合实验室*的框架内,海军集团和Centrale Nantes团队印制了一个重量超过300千克的大型几何复杂螺旋桨叶片。

通过增材制造,可以设计出先前无法使用标准生产技术制造的零件。这种颠覆性技术沉积(添加)材料而不是通过机械加工来减去材料。通过提升传统工艺所施加的限制,这些技术为创新零件设计和装配铺平了道路,从而为螺旋桨的生产铺平了道路,为海上船舶提供了更高的效率:性能(自主性和推进力),隐形和闪电。

海军集团海军研究技术研究中心主任Vincent Geiger强调了这些初步结果的重要性:

 

打印此演示器是通过增材制造制造创新螺旋桨的重要一步。这些初步结果意味着可以设想对使用它们的船舶进行短期螺旋桨的短期调试。

 

Jean-YvesHascoët教授是Gera实验室(UMR CNRS 6183)的Centrale Nantes快速制造平台的负责人,他是增材制造领域的国际专家。他解释说:

 

增材制造是一个提供无限可能性的过程:使用的材料更少,附加功能的集成和几何复杂的零件装配。它允许新设计,减轻重量,降低制造成本。

 

Centrale Nantes拥有工业设备和在叶片生产所需的轨迹生成和增材制造方面的广泛专业知识。

 

*海事技术联合实验室:海事技术联合实验室于2016年成立。它是一个联合工业/研究实验室,其总体目标是汇集南特中心,南特大学和海军集团的学术和工业专业知识。为海军集团在军事造船领域的工业应用创造合格的创新。

Naval Group and Centrale Nantes have printed the first full-scale propeller blade demonstrator for military applications using additive manufacturing. Within the framework of the Joint Laboratory of Marine Technology* launched in 2016, Naval Group and Centrale Nantes teams have printed a large geometrically complex propeller blade weighing over 300 kg.

With additive manufacturing it is possible to design parts that could not be made previously with standard production technologies. This disruptive technology deposits (adds) material as opposed to subtracting it by machining. By lifting the limits imposed by traditional processes, these technologies pave the way for innovative parts design and assembly, and thus for the production of propellers providing greater efficiency for ships at sea: performance (autonomy and propulsion), stealth and lightening.

Vincent Geiger, Director of Naval Group’s Naval Research Technology Research Center, stressed the significance of these initial results:

Printing this demonstrator is a major step towards the manufacture of innovative propellers by additive manufacturing. These initial results mean that it’s possible to envisage the short-term commissioning of differentiated propellers for the ships that will use them.

Professor Jean-Yves Hascoët, who heads up the Rapid Manufacturing Platform at Centrale Nantes, in the GeM laboratory (UMR CNRS 6183), is an international expert in additive manufacturing. He explained that:

additive manufacturing is a process that offers unlimited possibilities: less material used, integration of additional features and geometrically-complex parts assembly. It allows for new designs, weight savings, lower manufacturing costs.

Centrale Nantes has the industrial means and the extensive expertise in trajectory generation and additive manufacturing required for blade production.

*Joint Laboratory of Maritime Technology: The Joint Laboratory of Maritime Technology was created in 2016. It is a joint industry / research laboratory whose general objective is to pool the academic and industrial expertise of Centrale Nantes, the University of Nantes and Naval Group in order to generate qualified innovation for Naval Group’s industrial applications in the field of military shipbuilding.
