Inner ring flame tube cooling assembly suitable for oil flinger combustion chamber

The invention discloses an inner ring flame tube cooling assembly suitable for an oil flinger combustion chamber, and relates to the technical field of oil flinger combustion chambers, the inner ring flame tube cooling assembly comprises a combustion chamber, a diffuser and a sealing ring, an annular cavity is formed between the combustion chamber and the diffuser, and an air flow channel is formed between the combustion chamber and the sealing ring; an outlet of the combustion chamber is provided with a plurality of hollow supporting plates, and airflow flows into the hollow supporting plates through the annular cavity and is led into the airflow runner to flow to an inlet of the combustion chamber. The hollow supporting plates are arranged at the outlet of the combustion chamber, so that the rigidity of the combustion chamber is improved, the connection mode of the front cylinder of the combustion chamber is simplified, and an airflow is introduced into the airflow runner through the annular cavity to flow
