Deep Blue Aerospace is a commercial aerospace company focused on reusable launch vehicles and advanced rocket propulsion systems. The company invests in high-performance engine development and rapid manufacturing to reduce launch costs. Farsoon Technologies is a global manufacturer of industrial metal additive manufacturing systems, supporting aerospace sectors with large-format metal powder bed fusion solutions.
Developing a large rocket engine combustion chamber requires resistance to extreme heat and pressure while maintaining structural precision and combustion efficiency. Key challenges included producing complex internal cooling channels, ensuring material density at scale, reducing assembly steps and meeting aerospace quality standards.
A large-format metal powder bed fusion system was deployed to manufacture the combustion chamber as a near-integrated structure. The approach enabled intricate regenerative cooling channels, structural optimisation, fewer weld joints and improved thermal performance.
The chamber was built using an industrial metal additive manufacturing platform with stable thermal control. Design optimisation and simulation were conducted to evaluate thermal stress and flow performance. Process parameter development, post-processing and validation ensured aerospace-grade dimensional accuracy and structural integrity.
The project demonstrated successful large-scale metal additive manufacturing of a rocket combustion chamber. It reduced assembly complexity, enhanced cooling efficiency and shortened development cycles compared to conventional manufacturing.
