Pulsed inductive thrusters or PITs as they are commonly abbreviated are a form of spacecraft propulsion that uses perpendicular electric field and magnetic fields to accelerate a propellant. A nozzle releases a puff of gas (usually argon) which spreads across a flat induction coil of wire about 1 meter across. A bank of capacitors releases a pulse of electric current lasting 10 microseconds into the coil, generating a radial magnetic field. This electromagnetic induction a circular electrical field in the gas, ionizing it and causing the ions to revolve in the opposite direction as the original pulse of current. Because their motion is perpendicular to the magnetic field, they are pushed out into space. Unlike other electromagnetic drives, PIT requires no electrodes (which are susceptible to erosion) and its power can be scaled up simply by increasing the number of pulses per second. A 1-megawatt system would pulse 200 times per second. ==See also== * Spacecraft propulsion ** Ion thruster *** Electrostatic ion thrusters *** Hall effect thrusters *** Field Emission Electric Propulsion *** Pulsed inductive thruster Spacecraft propulsion
"Unlike other electromagnetic drives, PIT requires no electrodes (which are susceptible to erosion)..." At least some ion drives use electrodes which are not "susceptible" to erosion in that that eroding them is just precisely how the reaction mass is supplied, with new mass feeding in. Technically, yes, they are eroding - but the equipment isn't wearing away. Example: a drop of liquid metal at the end of a hollow feeder needle is drawn out into a point by an electrostatic field, then ions emerge from that point. PML.
