Abstract

This work presents an experimental campaign to optimize the performance of electro-aerodynamic (EAD) thrusters through nonuniform emitter arrangements. The study examines the impact of emitter configurations on thrust and thrust-to-power coefficients

$\boldsymbol {C}_{\boldsymbol {T}}$

and

$\boldsymbol {C}_{\boldsymbol {TP}}$

. Different emitter arrangements, including collinear and staggered arrays, are tested using thrust, electrical, and velocity measurements as diagnostics. The tests are parametrically performed for different sizes (chords) of the collector electrodes. Results reveal that nonuniform emitter configurations outperform standard arrays, in particular, with short chord collectors, widely spaced apart. An optimal configuration for

$\boldsymbol {C}_{\boldsymbol {T}}$

is identified among the staggered ones. In addition, droplet collectors demonstrate competitive performance compared to airfoil collectors.

非均匀发射阵列对EAD推进器性能的增强

本工作提出了一个实验运动，以优化性能的电气动（EAD）推力器通过非均匀的发射器布置。该研究考察了发射器配置对推力和推力功率系数$\boldsymbol {C}_{\boldsymbol {T}}$和$\boldsymbol {C}_{\boldsymbol {TP}}$的影响。使用推力、电学和速度测量作为诊断，测试了不同的发射器布置，包括共线和交错阵列。对不同尺寸（弦）的集电极进行参数化测试。结果表明，非均匀发射极配置优于标准阵列，特别是短弦集热器，间距大。$\boldsymbol {C}_{\boldsymbol {T}}$的最优配置是在交错的配置中确定的。此外，与翼型收集器相比，液滴收集器表现出具有竞争力的性能。
