Abstract

The advent of microelectronics and space technology has enabled the design and testing of many micro-electric propulsion technologies. The University of Surrey has been designing and testing 3 types of thrusters for various space missions, many of which will soon be tested in orbit: The Helicon Double Layer Thruster is an RF thruster that does not use any grids and has been tested on a thrust balance at Surrey, producing thrust of 2–5 mN an Isp of 400s at 500W The Hollow Cathode Thruster is a Cathode used as an electrothermal thruster for microsatellite and has been tested to produce thrust at 2 mN, Isp of 150s at 100W The Pulsed Plasma Thruster is a micro thruster for nanosatellites, to be flown on the STRanD-1 nanosatellite mission in 2011 Micro (EP) solutions open a whole new dimension in small satellite missions, enabling new missions for space exploration, low altitude earth observation and many others. The paper will address the key micro-EP technologies and highlight some new space mission concepts which use EP technologies.
用于小型卫星任务的微电力推进(EP)解决方案
微电子技术和空间技术的出现使许多微型电力推进技术的设计和测试成为可能。萨里大学一直在为各种太空任务设计和测试三种类型的推进器,其中许多将很快在轨道上进行测试:Helicon双层推力器是一种射频推力器,不使用任何栅格,在萨里的推力平衡上进行了测试,在500W时产生2 - 5 mN的推力和400s的Isp。空心阴极推力器是一种阴极,用作微型卫星的电热推力器,已经过测试,在100W时产生2 mN的推力和150s的Isp。脉冲等离子体推力器是纳米卫星的微型推力器。微型(EP)解决方案为小型卫星任务开辟了一个全新的维度,使空间探索、低空地球观测和许多其他任务成为可能。本文将讨论微极电技术的关键,并重点介绍一些利用极电技术的航天任务新概念。
