航天器（SC）的评估趋势之一是寿命和星上功率的增长，这刺激了使用电推进系统（EPS）进行SC的位置保持或主推进。目前正在建造功率超过20千瓦、寿命为10 - 15年的航天器。高功率（数百千瓦，甚至兆瓦）水平的电力推进未来具有挑战性的任务的兴趣重新。本文讨论了阳极层推力器在多模式大功率电推进系统设计中的发展趋势和取得的成果。TAL技术目前处于研究和开发阶段，但它已显示出相当有前途的性能。其主要性能指标为：比冲1000 ~ 8000秒，推力几克~几百克，功率几百瓦~几百千瓦。TAL推进器可以使用各种惰性气体（氦气、氪、氩）、它们的混合物和可冷凝推进剂（铋、铯、镉）作为推进剂。因此，TAL特性允许它们应用于大多数任务，例如：航天器（SC）气动阻力补偿，SC轨道校正和定向，SC轨道插入，行星际和深空任务。此外，还有TAL技术的前瞻性特征将被纳入下一代EPS：多模式能力推进器和几个同时操作的推进器组件应用。
One of the spacecraft (SC) evaluation tendencies is lifetime and onboard power growing and it stimulates using electric propulsion system (EPS) for SC stationkeeping or primary propulsion. Spacecrafts with power level over 20 kW and with 1015 years of life are currently being implemented. Interest in high power (hundreds of kilowatts or even megawatt) level electric propulsion for future challenging missions is renewed. Thrusters with anode layer (TAL) development tendencies and obtained results in regard to multi-mode high power electric propulsion systems design are discussed in the paper. TAL technology is on the research and development stage for now, however it has shown quite promising performance. Demonstrated main characteristics values are: specific impulse from 1000 up to 8000 seconds, thrust from several grams up to hundreds grams and power from hundreds watts up to hundred kilowatts in single thruster unit. TAL thrusters could use as a propellant various inert gases (Xe, Kr, Ar), their mixtures and condensable propellants (Bi, Cs, Cd) as well. Thus TAL characteristics allow their application for a majority of tasks such as: spacecraft (SC) aerodynamic drag compensation, SC orbit correction and orientation, SC orbit insertion, interplanetary and deep space missions. In addition there are TAL technology perspective features to be incorporated in the next generation EPS: multi-mode ability thrusters and several simultaneously operating thrusters assembly application.
