Abstract:
Along with the continuous improvement of liquid rocket engine properties, new features such as complexity, thin wall, multi-function, integration and light weight have emerged for engine key parts, which brings challenges for engine development and manufacturing, and demands the research of new processes and technologies. Laser rapid prototyping technology is a new one booming in recent years. With the technology, the metal parts of complex shape, high dimension precision, high structure density and stable performance could be directly produced by melting metal powder layer by layer with laser as heat source. Thus laser rapid prototyping technology shows a unique advantage in the manufacturing of liquid propulsion products. In this paper, the principle and classification of laser rapid prototyping technology are introduced, its research status and development trends at home and abroad are summarized, and its advantages and prospects applying in liquid rocket engines are elaborated.
