甩油盘是中小型航空发动机常用的燃油喷射装置，为后续甩油盘结构改进和燃烧室性能测试提供了参考和依据，该文开发了甩油盘雾化实验台，由供水系统、旋转系统、通风系统、测试系统、控制系统和数据采集系统组成。对供水压力、供水流量以及旋转系统振动值等关键运行参数进行监测与分析，结果表明：该实验台可以获得可靠的高精度实验数据。基于相位Doppler粒子分析仪（phase Doppler particle analyzer，PDPA）测试了某型甩油盘粒径数统计，以及Sauter平均直径（Sauter mean diameter，SMD）随转速的变化规律。结果表明：该型甩油盘粒径符合正态分布；SMD随着甩油盘转速的增加逐渐减小，在12 000 r/min后基本维持在41 μm。实验结果与已有文献结论相一致，进一步表明了该试验台的可靠性。
Fuel slingers are commonly used fuel injection devices for small and medium-sized aeroengines. This study developed a fuel slinger atomization test bench to provide reference data to improve fuel slinger designs and combustion chamber performance tests. The test bench included a water supply system, rotating system, ventilation system, test system, control system, and data acquisition system. Analyses of the key operating parameters such as the water supply pressure, water supply flow rate and vibrations of the rotating system shows that the test bench gives reliable, accurate experimental data. A phase Doppler particle analyzer (PDPA) was used to measure the particle size statistics and the variation of the Sauter mean diameter (SMD) for various rotational speeds. The experimental results show that the particle size in the fuel slinger has a normal distribution and the SMD decreases with increasing fuel slinger speed with an SMD of 41 μm above 12 000 r/min. The experimental results are consistent with the conclusions of previous papers, further indicating the reliability of the test bench.
