- 摘要:
- 设计高性能喷注器、提高发动机比冲性能是发动机设计者一直追求的目标。对于直流互击式喷注器,鲁泊数和孔径比是影响喷注器性能的两个关键参数,而且两者之间有一定关联。为了初步研究鲁泊数和孔径比参数对直流互击式喷注器性能的影响,合理匹配两者的关系,设计了三种状态的喷注器,进行了混合比分布试验和热试车考核。结果表明,兼顾鲁泊数和孔径比才能使氧化剂和燃料达到最佳混合效果,提高燃烧效率。
- Abstract:
- To design a high performance injector and to improve engine impulse performance are the permanent goals of engine designers. The Rupe number and the ratio of injection orifice diameter are two key parameters affecting unlike impinging injector performance, and they are closely interrelated. To study the effect of Rupe number and ratio of injection orifice diameter on unlike impinging injector performance and to match reasonably the relationship between Rupe number and ratio of injection orifice diameter, three kinds of injectors were designed, and relevant mixture ratio distribution tests and hot fire tests were performed. The results show that mixture characteristics of oxidizer and fuel can be improved only by taking into account both Rupe number and ratio of injection orifice diameter,and thus combustion
