一种百尖端阵列式多孔电喷雾微推力器 Hundred-Tip Array Multi-Orifice Electrospray Micro-Thruster
- Supported attitude–orbit control trade studies for the array thruster and built a simulation model for unipolar/bipolar mode switching. Simulations verified Faraday shielding against electromagnetic interference, optimized sub-1 s fast-switch logic, and met 0.01° high-precision attitude control requirements.
- Led precision assembly and performance testing of thruster prototypes, including 3D-printed part verification and a pump-free propellant platform. Emission-current analysis confirmed ~90% suppression of tip corrosion by the remote electrode, supporting ~35% system mass reduction and long-life design with quantitative evidence.
This patent proposes a hundred-tip arrayed porous electrospray micro-thruster with pump-free transport to raise thrust and lifetime for micro/nano-satellite micro-thrust missions. It further describes a plume diagnostic system (four grids and programmable scanning for energy and parameter extraction) and a control method that decouples extraction from confinement for beam convergence and active regulation in microsatellite orbit control.
