Additively Manufactured Modular Thrust Chamber

Thrust chambers have historically been difficult to manufacture. They require extensive tooling and labor, and are expensive with long lead times. Thrust chambers were designed for manufacture using conventional machining. As a result, designs required multiple pieces to ensure machine tool access to each surface. The individual pieces would then be joined and assembled into a single thrust chamber. These joining operations typically required process development due to the complexity of the parts and the need for joining to provide a seal between parts. A faster, more reliable and affordable manufacturing method was desired.
