摘要
根据高温升燃烧室的设计要求,计算了燃烧室的总体尺寸,流量分配,通过流量分配以及燃烧室性能要求计算旋流器、掺混孔和冷却孔的尺寸及结构,并验证所设计的燃烧室满足设计要求。设计完成的燃烧室采用回流结构,分级分区的设计思路,研究成果对于新一代涡轴发动机燃烧室的设计具有一定的意义。
According to the design requirements of high temperature rise combustion chamber,the overall size and flow distribution of the combustor were calculated.The size and structure of hydrocyclone,mixing hole and cooling hole were calculated through flow distribution and performance requirements of combustion chamber.The designed combustion chamber was verified to meet the design requirements.The designed combustion chamber adopted the design idea of reflux structure and grading and zoning.The research results had certain significance for the design of the combustion chamber of the new generation turboshaft engine.
