0304779BoydThis award supports the PI's graduate student from the University of Michigan in a collaboration with Martin Tajmar of the Space Propulsion Laboratory at the Austrian Research Center in Seibersdorf, Austria. The collaboration will develop a first-principles model for Taylor cone droplet formation through a combination of experimental activities and steady state code development at the Austrian lab, which is a world leader in the development of field emission electric propulsion systems. FEEP is a technology suitable for spacecraft missions (such as the laser interferometer space antenna) requiring thrusts in the sub-milliNewton level and needing precise control abilities. The US and Austrian teams will investigate the effects of viscosity, time of formation of Rayleigh instabilities, and convection of vaporizing ions. A model of those effects will lead to optimized current levels in future FEEP thrusters, thereby achieving maximum mass efficiency for a given thrust.The project also fulfills a training objective. The project will allow the graduate student involved to benefit from performing research in another country. They will develop a heightened appreciation of the world around them while also learning important new technical skills.

0304779Boyd 该奖项支持 PI 的密歇根大学研究生与奥地利塞伯斯多夫奥地利研究中心空间推进实验室的 Martin Tajmar 合作。 此次合作将通过奥地利实验室的实验活动和稳态代码开发相结合，开发泰勒锥液滴形成的第一原理模型，该实验室是场发射电力推进系统开发的世界领先者。 FEEP是一项适用于需要亚毫牛顿级推力并需要精确控制能力的航天器任务（例如激光干涉仪空间天线）的技术。 美国和奥地利团队将研究粘度、瑞利不稳定性形成时间以及汽化离子对流的影响。 这些效应的模型将优化未来 FEEP 推进器的电流水平，从而实现给定推力的最大质量效率。该项目还实现了培训目标。 该项目将使参与的研究生能够从在另一个国家进行的研究中受益。 他们将提高对周围世界的欣赏能力，同时学习重要的新技术技能。
