Starting method of combustion chamber of turbofan engine

The invention relates to a starting method of a combustion chamber of a turbofan engine, and belongs to the field of turbofan engines. A starting structure of the combustion chamber of the turbofan engine, which is provided by the invention, can be used for guaranteeing reliable starting in severe environments of a low temperature, low pressure and the like through the structural design of the starting structure; the engine does not need to be subjected to sealability detection after being stored for a long time and is further reliable to start; the starting process of the combustion chamber has nothing to do with the property of fuel oil; the participation of the fuel oil is not needed in the starting process, and further, the repeated starting can be achieved. 本发明涉及种涡扇发动机燃烧室启动方法，属于涡扇发动机领域。本发明提供的涡扇发动机燃烧室启动结构通过其结构设计可以保证在低温、低压等恶劣环境下可靠启动；发动机在长时间贮存后无需进行密封性检测且启动可靠；燃烧室启动过程与燃油性质无关，启动过程中无需燃油参与；且可以重复启动。
