Description
Technical Field
The invention belongs to the field of electric thrusters, and particularly relates to a cusp field thruster for microwave-enhanced auxiliary ionization.
Background
The electric propulsion system has the advantages of higher thrust, high efficiency and long service life, receives more and more attention in space missions and gradually replaces the traditional chemical propulsion. In recent years, the rise of micro-nano satellites and a new-generation space science task have further demands on low thrust, low noise and high vector precision thrust. However, since the radio frequency ion thruster, the field emission thruster, the colloid thruster and the cold air thruster, which are the mainstream in the world, have the key problems of high complexity, narrow adjustable range, short service life and the like, it is necessary to develop a novel micro thruster.
The cusp field thruster is a novel electric propulsion concept appearing internationally, and has the advantages of low complexity, wide adjustable range, low noise and long service life due to the special magnetic field position type. The operating principle is that a cusped magnetic field is arranged in a ceramic channel of the cusped field thruster, most of the magnetic field is parallel to the wall surface except a magnetic tip, electrons mainly do spiral drifting motion along magnetic lines of force, and the electrons are difficult to cross the magnetic field and reach the wall surface. The particles rebound under the action of the magnetic mirror force until the particles collide with neutral particles to be ionized, and the generated ions are ejected out of the channel under the action of the axial electric field and are neutralized with electrons to generate thrust. However, the research on the miniaturized cusp field thruster finds that the thruster still has two defects: firstly, the thruster is undersized, so that the ionization space is insufficient, and the working medium utilization rate is low; secondly, the thrust can only be adjusted by flow and voltage, the adjusting means is less, and the adjusting precision is not high.
