燃油喷嘴性能试验器是测试航空发动机燃油喷嘴喷雾锥角、锥角偏心度及燃油分度不均匀度等性能指标的试验设备。针对技术要求,设计了一台喷嘴性能试验器,介绍了试验器的组成及工作原理,重点分析了液压系统,对测试过程作了简述。
Fuel nozzle performance tester is to test the aero-engine fuel nozzle spray cone angle, cone angle eccentricity and fuel indexing performance index test equipment. Aiming at the technical requirements, a nozzle performance tester was designed. The composition and working principle of the tester were introduced. The hydraulic system was analyzed emphatically, and the testing process was briefly described.
