Multi-part fluid chamber and method of manufacturing
A coupling system is utilized to form a multi-part rocket engine thrust compartment that maintains inner channels within walls of the thrust compartment for regenerative cooling. The coupling system includes an insert joint arranged between joint faces of a first segment and a second segment. The first segment and the second segment include inner edges that, when jointed together, form an inner wall. The joint insert is installed between the first segment and the second segment after the inner wall is formed and coupled to the first segment and the second segment. The joint faces of the first segment and the second segment include extending feature to form a flow passage along with cavities at least partially defined by the joint insert.
