Abstract

The invention discloses an engine, a combustion assembly of the engine and an integrated designing and manufacturing method for the combustion assembly. The combustion assembly comprises a flame tubeand nozzles; the flame tube comprises a main body; a combustion chamber is formed in the main body; through holes are formed in the main body and enable the combustion chamber to communicate with theoutside of the flame tube; the combustion chamber comprises a head part and a tail part which back onto each other; gas enters the flame tube from the head part and the through holes and flows out ofthe flame tube from the tail part; the nozzles are arranged on the head part; and the nozzles and the flame tube are integrally manufactured through an additive manufacturing technology. According tothe engine, the combustion assembly of the engine and the integrated designing and manufacturing method for the combustion assembly, the combustion assembly of the engine is integrally designed and manufactured by utilizing the additive manufacturing technology, the flame tube and the nozzles are fused into a whole, the structure of the combustion assembly can be simplified, supporting and connecting structures among components of the combustion assembly can be reduced, machining can be facilitated, weight reduction can be facilitated, the reliability can be improved, and the machining and maintenance cost can be lowered.
