| 摘 要： | 本文对某型航空发动机燃油喷嘴的工作特性和雾化质量进行了试验研究。主要包括：测定喷嘴的流量特性，通过数码照相和计算机图像处理测定喷嘴在不同压力下的喷雾锥角，利用相位多普勒粒子分析仪（PDPA）和激光多普勒测速仪（LDV）测量喷嘴的雾化粒度SMD及尺寸分布。通过对上述试验结果的分析，得出了一些有价值的结论。这些结论对该发动机燃油喷嘴的改进提供了重要依据。

| Abstract: | The operation performance of an aero engine fuel nozzle was tested and investigated.The tests include: the fuel flow characteristic of the injector was investigated,the spray angle was measured by digital camera and computer photo processing,and the spray particle size(SMD) and size distribution were determined by the Phase Doppler Particle Analyzer(PDPA) and Laser Doppler Velocimeter(LDV).By means of analyzing the test results some valuable conclusions have been obtained.These results provide an important foundation to improve the aero engine fuel injector. |
