摘要

摘要: 卫星等航天器在轨运行期间，通过喷气实现姿态控制、轨道调整等特定需求.喷气射流与电离层相互作用，能够引起电离层环境改变，对星载设备产生重要影响.通过研究航天器在轨发动机喷气射流在电离层中的动力学及化学反应过程，建立射流的电离层效应物理模型，模拟了不同射流量及高度条件下喷气射流的运动过程、密度分布及电离层扰动效应.仿真结果表明，相同高度下，随着射流量增加，电离层扰动效应逐渐增强；相同射流量条件下，随着高度增加，电离层扰动效应逐渐减弱，扰动区域逐渐扩大.

Abstract: Satellite and other spacecraft need to be operated in a specific space environment, and the change of space environment has important influence on the orbit and life span of spacecraft. During the running of satellite and spacecraft in orbit, specific requirements, such as attitude control and orbit adjustment are implemented by jet. The interactions between the jet and the ionosphere can cause the ionosphere environment change, which may affect the normal work of the spacecraft. In this paper, the kinetics and chemical reactions process of the spacecraft jet are studied, and an ionospheric disturbance physical model of spacecraft jet is set up. The dynamic process, density distribution and ionospheric perturbation effect of different jet weight, jet time and jet altitude are simulated. The simulation results show that, at the same jet height, with the increase of jet weight, the perturbation effect of the ionosphere increases; at the same jet weight, with the increase of jet height, the perturbation effect of the ionosphere gradually weakens and the perturbation area gradually increases. The results are of great significance for the design of spacecraft with maneuverability and the study of physical mechanism and control factors of ionospheric disturbance.
