英文摘要： Stable and efficient on-orbit control is one of the key technologies to promote applications of nanosatellite(<10kg). In order to resolve the problem of low efficiency, large weight and complex structure in plasma propulsion technology, a novel ferroelectric cathode based microplasma thruster is proposed. The mechanism and key technology is investigated in this project. The main research topic include: mechanism of ferroelectric microplasma generation and microplasma beam extraction from the microscale nozzle, as well as propulsion mechanism; optimal design and fabrication of thruster based on MEMS technology; and reliability analysis based on static and dynamic testing. The purposes of this project are expected to develop a new microscale propulsion method for orbit controlling of nanosatellites with high efficiency and light weight, which has important theoretical significance and practical value.
