本文提出了霍尔效应推进器寿命预测的半经验模型。该模型基于推进器运行最初几个小时内已知溅射的推进器绝缘体溅射预测。给出了预测的物理和数学模型及其实现算法。还提供了模型实验验证的示例。该模型在标称功率为 325 和 900 W 的霍尔效应推进器的寿命测试中得到了验证。
The semi-empirical model of Hall-effect thruster lifetime prediction is presented in this paper. The model is based on the thruster insulators sputtering prediction by the known sputtering in the first hours of the thruster operation. The physical and mathematical model of prediction and algorithm of its realization are presented. An example of experimental validation of the model is presented too. The model was validated during the life tests of Hall-effect thrusters with nominal power of 325 and 900 W.
