摘要

摘要: 针对航天器未来空间飞行任务对大功率电源的迫切需求，开展了基于电弧加热的高温气体磁流体（MHD）发电地面试验研究。利用长分段电弧加热器加热氩气试验工质，模拟MHD发电所需的温度和压力条件，通过注入铯种子的方式提高试验工质的电导率，成功进行了直通式和盘式MHD发电地面试验：在磁场强度1 T试验条件下，直通式发电机最大输出发电功率达到196 W；在磁场强度7 T试验条件下，盘式发电机最大输出发电功率达到10.5 kW。本研究工作验证了磁流体发电技术的前景，为更高功率的磁流体发电机研究及空间应用奠定了基础。

Abstract: The high power electric propulsion and energy system is in urgent demand for the next generation space exploration. This paper presents ground-based tests on the high-temperature magnetohydrodynamic(MHD) power generation system by utilizing arc heater. The required temperature and pressure conditions for power generation are provided by the arcjet and the conductivity of the testing gas is improved by injecting the seeding cesium. Linear and disk MHD power generation is successfully carried out respectively:the maximum output power of the linear MHD power generator reaches 196 W under the test condition of 1 T magnetic-field intensity, and the maximum output power of the disc generator reaches 10.5 kW under the test condition of 7 T magnetic-field intensity. It demonstrates the prospect of the MHD power generation technology and lays foundations for the research of the higher power MHD generator and space application.
