There is a large number of missions that have been or will be launched soon that utilize the electric propulsion (EP), which is considered a key technology for applications in present and future space missions. Accomplishing an accurate measure of the thrust is a key aspect of the laboratory verification of EP systems. In the case of ground conditions and direct measurements, it is complicated to verify the thrusters, especially for some high power (>5 kW) thrusters. For this reason, we have developed an indirect method for measuring thrust. We have carried out an experiment with a Hall effect thruster (operated in the 250 W power range) and compared results against direct thrust measurements. The difficulties in the indirect measurement are analyzed, which provides a basis for the development of indirect thrust measurement.

基于悬臂梁的间接推力架的开发

有许多已经或即将发射的利用电子推进（EP）的任务，这被认为是当前和未来太空任务中应用的关键技术。实现对推力的精确测量是EP系统实验室验证的关键方面。在地面条件和直接测量的情况下，验证推进器非常复杂，尤其是对于某些大功率（> 5 kW）推进器而言。因此，我们开发了一种间接测量推力的方法。我们使用霍尔效应推进器（在250 W功率范围内运行）进行了实验，并将结果与​​直接推力测量结果进行了比较。分析了间接测量的难点，为间接推力测量的发展提供了依据。
