Extrapolating ground test data of Hall effect thrusters to in-space operation
Abstract
The objective of this research is to resolve discrepancies between the ground tests and operating the Hall thruster in space. Such discrepancies are most often attributed to facility effects that pose significant challenges in assessing and predicting thruster lifetime. In addition, predictive modeling capabilities are necessary to extrapolate the lifetime estimation of the ground tests with shorter test time, as the goal of USSF needs to achieve 15,000-hour lifetime, 65% thruster efficiency over 1600-3500 s specific impulse with the goal of achieving 30,000-hour (3.4-year) lifetime by 2025.
