Rocket engine having a transition attachment between a combustion chamber and an injector

摘要

A rocket engine (20) has a combustion chamber (22), an injector (38), and an attachment (48) between the combustion chamber (22) and the injector (38). The attachment (48) includes an annular metallic deposit (50) joined to the chamber wall outer surface (30), and an annular transition ring structure. The transition ring structure has an annular step collar (46), and an annular adaptor ring (54) brazed to the annular step collar (46). The adaptor ring (54) is welded on one end to the injector (38) and on the other end to the metallic deposit (50). <IMAGE>
