Abstract

The invention discloses a mixed thruster performance optimization method. Starting from parameters representing different thruster performances, a relatively large value is selected in a selectable range of the parameters to start value assignment, so that not only the performance of a single thruster but also the performance of a mixed thruster can achieve the best, an optimal power ratio of themixed thruster and the corresponding total thrust force, total specific impulse and total efficiency can be quickly obtained, and the power, thrust force, specific impulse and efficiency of an annularion thruster and a Hall thruster are obtained. According to the performance optimization method, the performance advantages of all the thrusters can be utilized; the performance of the mixed thrusteris optimized; and the optimal power ratio of the mixed thruster and the ranges of the corresponding total thrust force, total specific impulse and total efficiency can be quickly obtained.

Description

technical field [0001] The invention relates to the field of plasma, in particular to a method for optimizing the performance of a hybrid thruster. Background technique [0002] The performance index is an important basis for judging whether the spacecraft uses a thruster or whether the thruster can be successfully applied and meets the needs of the spacecraft. It is also an important assessment basis for judging whether the design of the thruster is successful. Existing thrusters need to go through a large number of performance parameter tests on the ground before their in-orbit application, so that their optimal working parameters can be finally determined and solidified as the rated working point. There are many parameters that affect the performance of the thruster, and the mechanism is complex, and the continuous iteration through experimental verification is not only time-consuming, labor-intensive, but also expensive. [0003] The electric thruster products that have...
