摘要

金属增材制造技术是一种基于离散–堆积原理的先进制造技术，为液体火箭发动机的设计制造带来了颠覆性的变化。推力室作为液体火箭发动机的核心部件，采用增材制造技术可实现结构的轻量化、集成化设计制造，以及燃烧室等热端部件内流道结构的整体制造，提高产品的性能和可靠性，缩短制造周期、降低制造成本。本文对金属增材制造技术在液体火箭发动机推力室中的应用情况进行了综述，并对未来的技术发展进行了讨论。

Abstract

Metal additive manufacturing technology is an advanced manufacturing technology based on the discrete–accumulation principle

which has brought a subversive progress to the design and manufacture of liquid rocket engines. As the core component of liquid rocket engine

the thrust chamber can realize the lightweight and integrated design and manufacturing of the structure

as well as the overall manufacturing of the flow channel structure of the hot end components such as the combustion chamber

improve the product performance and reliability

shorten the manufacturing cycle and reduce the manufacturing cost. In this paper

the application of metal additive manufacturing technology in the thrust chamber of liquid rocket engine is reviewed

and the future development of the technology is discussed.
