While electrospray devices have been used in a variety of applications for decades, they have recently seen a surge in research within the field of electric propulsion. These research efforts have helped significantly improve the understanding of electrospray thruster operation and optimization, however they have primarily been focused on capillary-based, droplet emitting devices due to the more readily available manufacturing techniques. In contrast, ion emitting, porous-media-based electrospray devices are less developed both theoretically and experimentally. Presented here are fabrication methods and thruster characterization results for an entirely conventionally machined, high performance porous-media electrospray thruster. The goal of this work was to explore the performance capabilities of an ion-mode electrospray thruster which could be fabricated and tested rapidly using techniques readily available to virtually any institution, with the hope of enabling more academic a...

完全传统加工的高性能多孔介质电喷雾推进器的制造和表征

尽管电喷雾装置已经在多种应用中使用了数十年，但最近它们在电推进领域中的研究激增。这些研究成果极大地改善了对电喷雾推进器操作和优化的理解，但是由于更易于获得的制造技术，它们主要集中在基于毛细管的液滴发射装置上。相反，从理论上和实验上都较少开发基于离子发射的，基于多孔介质的电喷雾装置。这里介绍的是整个常规加工的高性能多孔介质电喷雾推进器的制造方法和推进器特性结果。
