The invention discloses a single-tube combustion chamber outlet transition section design method and a transition section, relates to the technical field of combustion chamber design, and aims to solve the problems of difficulty in early-stage modeling and difficulty in later-stage modification due to transition forming by utilizing multiple sections in the conventional transition section design. According to the technical scheme, the outlet transition section comprises an inlet, a transition section body and an outlet, and the intersection line of the transition section body and the plane forming 90 degrees with the plane passing through the center axis of the inlet and the center axis of the outlet is defined as a left side molded surface line and a right side molded surface line; an intersection line of a plane forming a 0-degree angle with a plane passing through the central axes of the inlet and the outlet and the transition section body is defined as an upper side molded surface line and a lower side mo
