飞机高能束增材制造结构研究

轻质高效、长寿命、多功能、低成本、快速响应制造是现代飞机结构技术的发展方向,但受限于传统制造技术,一些创新的结构存在"设计得出却造不出"的问题。高能束增材制造技术的发展为新概念结构工程的实现提供了契机。基于高能束增材制造技术,针对现代飞机结构特征需求,提出了大型整体化、梯度复合化和功能结构一体化等发展方向,创建了新概念构型,开展了设计与评定方法研究,提出了基于技术成熟度的工程化验证模式。

Aircraft Structures Technology Based on Power Beam Additive Manufacturing

The development direction of modem aircraft structures technology are lightweight,high efficiency,long life,multi-function,low cost,and rapid response manufacturing.Limited by traditional manufacturing technology,some innovative structures couldn't be made out.The additive manufacturing,using laser and electron power beam,offers an opportunity for the engineering application of innovative structures.Based on additive manufacturing technology and in the view of the requirements of modern aircraft structure,we developed large-scale integration,multiple gradients,and functional structure integration,created innovative structures,made a research of the design and evaluation,and presented engineering verification mode based on the technical maturity.
