Research Abstract & Technology Focus

FEEP thrusters stand out due to their accurate, adjustable thrust capabilities that range from sub-μN to mN, their ability to be turned on or off instantly, their high specific impulse, and their compact, safe, and straightforward design. They use a liquid metal propellant, such as indium, eliminating the need for pressurized tanks, external pumps, or hazardous materials, facilitating quick and seamless integration. This blend of characteristics makes them well-suited for small satellites and scientific missions that demand precise maneuvering, such as drag-free control. A performance assessment of FE microthrusters is conducted. An indium FEEP microthruster is detailed. The neutralization process of an ion thruster using a CNT FE cathode is examined. The concepts of NanoFEEP and MEMS ion thrusters are discussed. Feedback control mechanisms for FE thrusters are outlined.
