A combustion chamber assembly group includes a burner seal with a bearing section that extends along a longitudinal axis and has a passage hole for positioning a fuel nozzle at a combustion chamber of an engine, and a heat shield which, when mounted according to the intended use at the combustion chamber of the engine, is located inside the combustion space of the combustion chamber and has a passage hole through which the bearing section of the burner seal extends. The burner seal that is manufactured in an additive manner and the heat shield form a constructional unit in which the heat shield is received at least partially between a radially outwardly pointing opening edge of the burner seal and a radially outwardly extending web of the burner seal, so that any separation of the heat shield from the burner seal along the longitudinal axis is excluded.
Combustion chamber assembly group, comprising
Combustion chamber assembly group according to any of the preceding claims, characterized in that the opening edge (40) extends radially outwards up to the height of a radially outermost edge (2b) of the heat shield (2) or beyond this radially outer edge (25ba) of the heat shield (2), so that, when viewed from the combustion space (23) along the longitudinal axis (L), the opening edge (40) completely covers the heat shield (2).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the opening edge (40) extends at an opening angle (a) in the range of approximately 20° to 50° with respect to the longitudinal axis (L).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the heat shield (2) forms an embracing section (2c) that engages around the at least one radially outwardly extending web (42) of the burner seal (4).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the constructional unit of burner seal (4) and heat shield (2) is affixed via the heat shield (2) at a combustion chamber component (5) that borders the combustion space (23).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the opening edge (40) is formed to be symmetrical with respect to the longitudinal axis (L).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the heat shield (2) and/or the burner seal (4) have at least one cooling air hole (14) and/or at least one cooling rib or cooling nub (29).
Combustion chamber assembly group according to any of the preceding claims, characterized in that the combustion chamber assembly group comprises at least two burner seals (4) and the heat shield (2) has at least two passage holes (26) through which respectively one bearing section (41) of one of the at least two burner seals (4) extends.
Method for manufacturing a combustion chamber assembly group comprising a burner seal (4) with a bearing section (41) that extends along a longitudinal axis (L) and that has a passage hole (400) for positioning a fuel nozzle (17) at a combustion chamber (BK) of an engine (T), and a heat shield (2) which, when mounted according to the intended use at the combustion chamber (BK) of the engine (T), is located inside the combustion space (23) of the combustion chamber (BK) and has a passage hole (26) through which the bearing section (41) of the burner seal (4) extends,
