“…Spacecraft using plasma thrusters need a thrust vector control (TVC) device to modify the direction of the thrust force during the mission. Deflections of about 8°-10°in all directions are sufficient to compensate center of mass displacements and to cover the requirements of the vast majority of current propulsive missions [1,2]. Present TVC solutions consist of mounting the thrusters on complex and heavy gimbaled platforms [3,4] or robotic arms [5].…”

A 3D, steerable magnetic nozzle is presented that enables contactless thrust vector control of a plasma jet without any moving parts. The concept represents a substantial simplification over current plasma thruster gimbaled platforms, and requires only a small modification in thrusters that already have a magnetic nozzle. The characteristics of the plasma expansion in the 3D magnetic field and the deflection performance of the device are characterized with a fully-magnetized plasma model, suggesting that thrust deflections of 5-10 deg are readily achievable.

“…However, the sputtering process in the plates causes excessive damage (although, in case of low deflection, it is still possible to manage and control the grid erosion) and the formation of plasma sheaths can significantly decrease the vectoring ability by changing the surrounding electrical field. Other techniques, proposed in earlier literature for larger-scale systems, include the use of an electrostatic field applied in the holes of the grids, as well as methods to generate a mechanic translation of the grids [30].…”

performance and potential operational issues. Results of numerical simulations conducted to optimize the design of the heating and expansion slots, as well as a detailed description of the manufacturing steps for the conventional micro-resistojet concept, are presented. Some intended steps for future research activities, including options for thrust intensity and direction control, are briefly introduced.
